2. DESCRIPTION OF THE INSTRUMENT

2.1. Presentation

This comprehensive range of linear power supplies with digital displays is designed to meet the requirements of educational establishments, laboratories and maintenance departments.

It offers:

• a high level of operating safety by guaranteed insulation of the outputs from the mains when used at an extra low safety voltage,
  • comprehensive protection systems,
  • top-grade ergonomics.

The quality of the signal delivered, the precision of the display and the robustness of the housing make them top-level laboratory instruments.

• The AX 501 is a power supply with a single output.

It enables simultaneous display of the output voltage and current, as well as providing a voltage adjustable from 0 to 30 V for a variable current of 0 to 2.5 A (75 W).

- The AX 502 is a version of the AX 501 with dual outputs.

It has the same characteristics as the AX 501 with two 0 to 30 V / 0 to 2.5 A (150 W) outputs which can be wired in series, in parallel or coupled (TRACKING function) ± 30 V.

• The AX 503 and AX 503F are a triple power supplies.

They comprise two 0 to 30 V / 0 to 2.5 A (150 W) power supplies. The coupling of the 2 main units is identical to that on the AX 502.

They also have an adjustable 2.7 to 5.5V / 5A output for supplying logic circuits at 3 or 5V. Reminder : AX 503F (fixe) : 3.3 V and 5 A.

2.2. Controls

2.2.1. On / Off switch

The On/Off switch on the front panel is used to switch the power to the power supply on and off.

2.2.2. Potentiometers

* Voltage adjustment :

• Set the regulated voltage by turning the large potentiometer (coarse adjustment) to the right (increasing values).
• Set the regulated voltage by turning the small potentiometer (fine adjustment) to the right (increasing values). The fine adjustment range represents approximately 10% of the main range.
• The value of the voltage is displayed in real time.

* Current adjustment :

• Adjust the value of the limit current by turning the potentiometer to the right (increasing values).
• The current value displayed is the value of the output current.

2.2.3. "LIMIT" LED

The current value displayed is the value of the output current.

If the value reaches the defined current limit value, the "LIMIT" LED lights up and the power supply automatically switches to "current" regulation mode; the output current is then no longer regulated.

2.2.4. "TRACKING" switch (AX 502, AX 503 and AX 503F)

2.2.4.1. "TRACKING" mode

This control enables two "0 - 30 V" sources to be controlled in series mode.

When the "TRACKING" pushbutton is set to "ON", it sets up a series connection between the "-" terminal of the "MASTER" power supply and the "+" terminal of the "SLAVE" power supply. The external terminals are used to connect the points in the circuit to be powered.

Only the voltage settings of the "MASTER" module, which cause the voltages of the "MASTER" and "SLAVE" modules to vary proportionally, are then used.

2.2.4.2. "TRACKING" LED

When the "TRACKING" LED is on, it means that the "TRACKING function has been activated.

2.2.5. Digital "LED" display

A separate display allows you to view the voltage (in green) and the current (in red) simultaneously for the 30 V units.

The displays are provided by 3-digit LED indicators with a resolution of 0.1 V for the voltage and 10 mA for the current.

2.2.6. "+" and "-" output terminals

The female two-pin "+" and "-" safety terminals ( 4 mm) are used to connect the outputs to the points of the circuit to be powered by means of safety leads only.

2.2.7. "EARTH" terminal

The terminal marked " 12 " is directly linked internally to the earth on the mains plug. It enables earthing of the circuit to be powered, if necessary.

Its male polarity and "green/yellow" colour coding will prevent any confusion in the connections.

Interruption of the protective conductor, whether inside our outside the power supply, is prohibited.

2.3. Power supply

The mains power supply is provided by the mains network at 115 or 230 V ± 10 % ; 50 - 60 Hz CAT II.

3. FUNCTION DESCRIPTION

3.1. Initial operation

• Connect the power lead to the mains once having checked on the label at the rear of the power supply, that the instrument is adapted to operate at the mains network voltage.
• No connection cables should be connected before powering up.
• Start up the power supply by setting the On/Off switch to "I".
• To power down the instrument, unplug the leads and then turn the switch to "0".

3.2. Use

3.2.1. Use of the AX 501 or use of the AX 502, AX503 and AX 503F as independent outputs

• Connect the power lead to the mains.
• Check that the voltage adjustment potentiometers and current adjustment potentiometer are turned to the left as far as they will go (minimum voltage and current).
  • Make sure that the "TRACKING" button is in the "OFF" position, i.e. not pressed, except AX 501.
• If necessary, connect the " 12 " terminal to the earth of the circuit to be powered (to provide protection) and the "+" and "-" terminals to the points of the circuit to be powered, using the connection cables.
  Check the quality and polarity of the contacts.
• Set the On/Off switch to "I". The "LIMIT" LEDs should be off.
• Set the voltage to be regulated by turning the "voltage" potentiometers to the right (increasing values): the voltage set point is displayed.
• Adjust the value of the limit current by turning the potentiometer to the right (increasing values). The current value displayed is the value of the output current. If the output current reaches the limit current value, the power supply automatically switches to "current" regulation mode, the "LIMIT" LED comes on and the voltage is not longer regulated.

Example: A short-circuited output (R = 0) leads to V = R*I = 0 and the current "I" may vary up to 2.5 A (operation with current limitation, "LIMIT" LED on).

Application connected Application

1: Measurement of the current consumed by the circuit

2: Adjustment of current limitation

3.2.2. Use of 2 power supplies in parallel (without "TRACKING") up to 5 A at 30 V max. (AX 502, AX 503 and AX 503F)

• With the "TRACKING" pushbutton released (OFF position, LED off), set the 2 power supplies ("MASTER" and "SLAVE") to the same output voltage value.

• With the "TRACKING" pushbutton released (OFF position, LED off), set the 2 power supplies ("MASTER" and "SLAVE") to the same current limitation value.
• Use a short lead to link the "+" terminal of one power supply to the "-" terminal of the other power supply: use the two "+" and "-" terminals that remain free to make the connection with the circuit to be powered.

3.2.4. Use of 2 power supplies in series with the "TRACKING" function (symmetrical ± 30 V sources) at 2.5 A max. (AX 502, AX 503 and AX 503F)

• Press in the "TRACKING" button ("ON", LED lit).
  The pushbutton is set to "ON" sets up a series connection between the "-" terminal of the "MASTER" power supply and the "+" terminal of the "SLAVE" power supply.

Procedure:

• In sequence (power supply a and then b), adjust the "current" potentiometers to define identical limit currents.
• Connect up to the circuit to be powered (external terminals of the "MASTER" and "SLAVE" power supplies).
• The "MASTER" source is on the left (a); set the required initial voltage.
  • The "SLAVE" source is on the right (b).
• In this function, only the voltage controls of the "MASTER" source (a) will be used from now on.
• The symmetrical "SLAVE" source (b) reacts to the "MASTER" source (a) voltage variations by proportional "tracking" variations in absolute values ("TRACKING" function).

For the use of symmetrical voltages (e.g. ± 15 V), one of the 2 terminals (MASTER "-" or SLAVE "+") will be connected to the circuit to be powered ("0" point).
