The EX355P is a digitally controlled version of the EX355 with an isolated RS-232 interface. Using mixed-mode regulation technology it provides 0 to 35V at 0 to 5A in a compact and lightweight unit.

The EX355P offers a low-cost solution for a basic programmable PSU, and will be sufficient for many applications where the sophistication and complexity of GPIB is not needed.

A simple command set allows remote control of voltage, current and output-enable together with read-back of metering values and operational status.

Local control is via three rotary encoders providing rapid and accurate setting of voltage and current for bench use.

Excellent line and load regulation are matched by low noise and good transient response. High power efficiency ensures that the unit remains cool without any fan noise.

The EX series has been designed to meet the stringent requirements of the latest relevant IEC standards for safety and EMC, including harmonics emissions. All outputs are intrinsically short circuit proof, and are protected against external voltages and reverse currents.

The wire which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.

The wire which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.

WARNING! THIS INSTRUMENT MUST BE EARTHED.

Any interruption of the mains earth conductor inside or outside the instrument will make the instrument dangerous. Intentional interruption is prohibited.

Connections

Output Terminals

All power connections are made from the front panel.

The load should be connected to the positive (red) and negative (black) terminals marked OUTPUT. Both are fully floating and either can be connected to ground.

The terminal marked 12 is connected to the chassis and safety earth ground.

RS232

9-pin D-connector for PC remote control with the following connections:

Pin Name Description

1	DCD	Linked to pins 4 and 6
2	TXD	Transmitted data from instrument
3	RXD	Received data to instrument
4	DTR	Linked to pins 1 and 6
5	GND	Signal ground
6	DSR	Linked to pins 1 and 4
7	RTS	Linked to pin 8
8	CTS	Linked to pin 7
9	-	No internal connection

Connect to a PC with a cable which has pins 2, 3 and 5 wired plus pins 1, 4 & 6 and pins 7 & 8 linked at the PC end.

Operation

Setting Up the Output

With the POWER switch on (I) and the output off the output voltage and current limit can be accurately preset using the VOLTAGE and CURRENT controls; the left-hand meter shows the set voltage and the right-hand meter shows the set maximum current.

When the □output switch is switched on, the ON lamp lights; the left-hand meter still shows the preset voltage but the right-hand meter now shows the actual load current.

Constant Voltage

The output voltage is adjusted using the coarse and fine VOLTAGE controls; the coarse control changes the voltage in 100mV steps and the fine control in 10mV steps. The CURRENT control sets the maximum current that can be supplied; the control changes the current in 10mA steps.

Constant Current

If the load resistance is low enough such that, at the output voltage set, a current greater than the current limit setting would flow, the power supply will automatically move into constant current operation. The current output is adjusted by the CURRENT control and the VOLTAGE controls set the maximum voltage that can be generated.

The CC lamp lights to show constant current mode.

Instantaneous Current Output

The current limit control can be set to limit the continuous output current to levels down to 10mA. However, in common with all precision bench power supplies, a capacitor is connected across the output to maintain stability and good transient response. This capacitor charges to the output voltage and short-circuiting of the output will produce a current pulse as the capacitor discharges which is independent of the current limit setting.

Protection

The output has intrinsic short-circuit protection and is protected from reverse voltages by a diode; the continuous reverse current must not exceed 3 Amps, although transients can be much higher.

Connection to the Load

The load should be connected to the positive (red) and negative (black) output terminals. Both are fully floating and either can be connected to ground.

Series or Parallel Connection with Other Outputs

The outputs of the power supply are fully floating and may be used in series with other power supply units to generate high DC voltages up to 300V DC.

The maximum permissible voltage between any terminal and earth ground ( 12 ) is 300VDC.

WARNING! Such voltages are exceedingly hazardous and great care should be taken to shield the output terminals for such use. On no account should the output terminals be touched when the unit is switched on under such use. All connections to the terminals must be made with the power switched off on all units.

It should be noted that the unit can only source current and cannot sink it, thus units cannot be series connected in anti-phase.

The unit can be connected in parallel with others to produce higher currents. Where several units are connected in parallel, the output voltage will be equal to that of the unit with the highest output voltage setting until the current drawn exceeds its current limit setting, upon which the output will fall to that of the next highest setting, and so on. In constant current mode, units can be connected in parallel to provide a current equal to the sum of the current limit settings.

Note that the output terminals are rated at 15A maximum; if several outputs are operated in parallel to source higher currents than this the junction should be made at a separate point, not one of the terminals.

Ventilation

The power supply is very efficient but nevertheless can generate significant heat at full power. The supply relies on convection cooling only and it is therefore important that ventilation is never restricted if performance and safety are to be maintained.

Remote Operation

Remote command format and the remote commands themselves are detailed in the Remote Commands chapter.

Baud Rate Selection

The Baud rate is set by pressing the OPTION SELECT/OK button until bAUD appears in the left-hand display; the right-hand display shows the current setting in the form of 960 for 9600 Baud etc. Change the Baud rate by pressing the CHANGE button to step the rate through all the possible options. When the required rate is displayed press OPTION SELECT/OK again to confirm and exit the rate change mode.

Remote/Local Operation

At power on the instrument will be in the local state with the Rem (remote) lamp off. When a command is received the remote state will be entered and the Rem lamp will be turned on. The rotary controls are not locked out by this action and the instrument will be returned to the local state if they are used; however, if the instrument receives another character from the interface, the remote state will again be entered.

Local operation of the rotary controls, output On/Off switch and CHANGE button can be disabled by pressing the OPTION SELECT/OK button until LoCL appears in the left-hand display; the right-hand display shows the current setting, on or OFF. Alternate presses of the CHANGE button selects on or OFF; when the required setting is displayed press OPTION SELECT/OK again to confirm and exit the change mode.

Local operation can be restored at any time by pressing the OPTION SELECT/OK button; if LoCL has been set to OFF the first press of OPTION SELECT/OK returns the instrument to local control and subsequent presses select the other modes as described above.

RS232 Character Set

Any ASCII code can be used. Bit 7 of ASCII codes is ignored, i.e. assumed to be low. No distinction is made between upper and lower case characters in command mnemonics and they may be freely mixed. The ASCII control codes between 00H and 31H are ignored, except for 0AH (Line Feed, LF) which is used as a command terminator.

Remote Commands

RS232 Remote Command Formats

The instrument's input buffer accepts a single command (or query) at a time, under interrupt, in a manner transparent to other instrument operations. Commands and queries must be sent as specified in the command list and must be terminated with the command terminator code 0AH (Line Feed, LF). Note that parameters are separated from the command header by one space (20H).

After a command has been sent the controller must wait at least 10ms from the command terminator before the next command (or query) is started, to allow the instrument to clear the input buffer.

Responses to queries are sent immediately. The controller must wait for the response to a query before the next command or query is sent. The instrument responds to the controller after every query as specified in the commands list. In every case a response is terminated by 0DH (Carriage Return, CR) followed by 0AH (Line Feed, LF).

is defined as character codes 00H to 20H inclusive. is ignored except in command identifiers. e.g. "*I DN?" is not equivalent to "*IDN?".

The high bit of all characters is ignored.

The commands are case insensitive.

Command List

This section lists all commands and queries implemented in this instrument. The commands are listed in alphabetical order within the function groups.

The following nomenclature is used:

<rmt>	<RESPONSE MESSAGE TERMINATOR>, CR followed by LF.
<nr1>	A number with no fractional part, i.e. an integer.
<nr2>	A number in a fixed point format, e.g. 11.52, 3.61, etc.

Miscellaneous Commands

*RST Resets the instrument to the default power-up settings (1.00V, 1.00A, output off).

*IDN? Returns the instrument identification. The exact response is determined by the instrument configuration and is of the form ,, 0, where is the manufacturer's name, defines the type of instrument and is the revision level of the software installed.

Maintenance

The Manufacturers or their agents overseas will provide repair for any unit developing a fault. Where owner wish to undertake their own maintenance work, this should only be done by skilled personnel in conjunction with the service manual which may be purchased directly from the Manufacturers or their agents overseas.

Fuse

The correct fuse type is:

10 Amp 250V HBC time-lag(T), 5 x 20mm.

Note that the main function of the fuse is to make the instrument safe and limit damage in the event of failure of one of the switching devices. If a fuse fails it is therefore very likely that the replacement will also blow, because the supply has developed a fault; in such circumstances the instrument will need to be returned to the manufacturer for service.

Make sure that only fuses of the required rated current and specified type are used for replacement. The use of makeshift fuses and the short-circuiting of fuse-holders is prohibited.

To replace a fuse, first disconnect the instrument from the AC supply. Remove the 6 cover securing screws and lift off the cover. Replace the fuse with one of the correct type and refit the cover.

Cleaning

If the PSU requires cleaning use a cloth that is only lightly dampened with water or a mild detergent. Polish the display window with a soft dry cloth.

WARNING! TO AVOID ELECTRIC SHOCK, OR DAMAGE TO THE PSU, NEVER ALLOW WATER TO GET INSIDE THE CASE. TO AVOID DAMAGE TO THE CASE OR DISPLAY WINDOW NEVER CLEAN WITH SOLVENTS.
