2. INTENDED USE

The laboratory power supply serves as DC voltage source to operate low voltage consumers. The adjustable output on the front side can be loaded up to the full nominal current. The output is protected against overload. Hazardous contact voltages >75 V/DC can be generated with the series connection of outputs of several power supplies. Insulated wires/measurement lines must be used for safety reasons from this voltage. This applies accordingly when using a single power supply unit with order number 1367576, since this provides an output voltage of up to 84 V/DC. The connection is made via 4 mm safety sockets.

Sufficiently dimensioned connection cables must be used. Too smaller conductor cross section can lead to overheating and fire.

The output data of the laboratory power supplies is as follows:

Type Output voltage Output current
CPPS-320-42 0 - 42 V/DC 0 - 20 A
CPPS-320-84 0 - 84 V/DC 0 - 10 A

The voltage and current is set continuously via digital rotary knobs with rough and fine adjustment to enable fast and precise value setting. The values are displayed in the clear display.

The power supply is remote controlled. The output voltage and the output current can be set via an external voltage (0 - 5 V/DC) or an external potentiometer (5 kOhm). The DC output is switched on and off via a switching contact.

Three freely programmed storage spaces can be allocated with different fixed voltages and current limits.

The power supply can be controlled to operate cyclical work flows via a PC with the software and USB connection included in the delivery scope. Up to 20 programmable voltage and current sets with different periods can be programmed for operation. The cyclical work flows can be repeated up to 999 times.

The device is overload and short circuit proof and includes a safety and temperature shutdown. The laboratory power supply is set up in protection class I It should only be connected to the protective contact sockets with protective earthing and a household AC voltage of 100 - 240 V/AC.

7. OPERATION

The laboratory network device is not a charger. Use a suitable charger with corresponding charging shutdown to charge batteries.

The housing surface heats up during longer operation with nominal load. Caution! Possible danger of burning. Therefore please ensure adequate ventilation of the power supply and never operate it partially or wholly covered, to avoid possible damage.

When connecting a consumer please ensure that it is switched off. A switched on consumer can cause sparks when connecting it to the output sockets of the power supply which can damage the sockets or the connected lines and/or terminals of these.

If you do not need your power supply, switch it off and disconnect it from the network. The displays stay on for a few seconds after switch off to discharge the internal condensators and save the parameters last set. Please ensure a sufficient conductor cross section of the DC connection lines since an overload can lead to cable fire.

a) Connecting the power cable

1. Connect the protective contact power cable provided to the cold device connection (12) at the power supply. Please ensure a secure fit.
2. Connect the power cable to a protective contact socket. The total length of the power cable to the socket should not exceed 3 m.

b) Setting up the device

Place the laboratory network device onto a stable, level and insensitive surface. Please ensure that the ventilation slits in the housing are not covered.

c) General information

The laboratory network device is controlled by microprocessors and is operated via two digital setting controllers (incremental encoders without end position) with button function. This enables the fine and rough control via a controller.

A system check takes place after switch on. The test status is displayed on both displays. The display sequence is as follows:

Display the current software status.

Segment test whether the display functions with all individual segments. Switch over to the normal operational display after this step.

The power supply enables operation in three modes. The following modes are possible:

Normal Normal operation: The voltage and current are set at the front.
Preset	Storage space operation: Three fixed voltages can be saved and directly selected via this preset function. The selection is made via the PRESET 1, 2, 3 selection buttons (8) and the settings via the (4, 5) setting controller.
Remote Ctrl	Remote control. The power supply can be remote controlled via an external voltage or an external potentiometer. The voltage and current can be remote controlled. The front setting controllers are inactive however, can be activated or deactivated again via the LOCK/UNLOCK (8) button.

The individual operating modes will be described in detail in the following chapters.

The power supply can be operated via the front setting controller in normal operation. Remove the connected consumer from the output (6).

Switch on the power supply via the POWER (1) on/off switch.

The display (2) lights up and the voltage and current display appears after a short self-test.

First set the current limit before each voltage setting. Your connecting cables can be damaged by a high current value. The output voltage can be limited by a low current value (<1A).

a) Set current limit

A protective mechanism limits the output current to protect the consumer or the connecting cables. The current limitation can be preset without short circuiting at the output. The power supply then delivers the maximum preset current.

1. Remove the connected consumer from the power supply.
2. Set the current limiter on the CURRENT setting controller (5) according to your needs.

3. Turn the controller and the current limitation value appears.

4. Switch on the power supply POWER on/off switch (1). The display (2) lights up and after a short self test the voltage and current display appears.

The display switches back to the current power display if a setting is not made within 2 seconds.

1. Turn the setting controller to the left or right to set the current limitation. This is represented by a slightly lighter digit. Briefly press the setting controller. The decimal point (1.0 or 0.1) of the setting range changes each time the button is pressed. Turning changes the value.
2. The setting can be made roughly (in the unit range) or precisely (in the one tenth range).
3. The display automatically switches back to normal display after approximately 2 seconds if the desired current value was set.

The power supply switches to current limitation mode and also reduces the voltage value if the preset current strength is reached in normal operation. This operation is signaled with the red C.C. status display (2).

b) Set output voltage

The output voltage can be set at the VOLTAGE (4) setting control. The rough and fine control is carried out in the same way as the setting of the current limitation.

It could be that the voltage setting requires approx. 1-2 seconds to adjust from a high to a low voltage value through the large control range.

The device works in constant voltage mode during normal operation. This means that the power supply delivers a constant preset output voltage. This mode is signaled with the green C.V. status display (2).

c) Connecting a consumer

When connecting a consumer to the power supply please ensure that it is switched off. The maximum power consumption of the connected consumer should not exceed the specifications in the technical data.

Dangerous contact voltages (> 75 V/DC) can be generated with the series connection of outputs of several power supplies, which could be a risk to life when touching. Only insulated accessories (connection cables, measuring lines etc.) may be used from this voltage. This applies accordingly when using a single power supply unit with order number 1367576, since this provides an output voltage of up to 84 V/DC. The use of metallic cables and contacts should be avoided. All these blank points should be covered with suitable, flame resistant insulating material or other measures and protected from direct contact and short circuits.

Please ensure a sufficient conductor cross section for the intended current strength.

1. Remove the connected consumer from the output.
2. Switch on the power supply via On / off switch POWER (1) The display (2) lights up and the voltage and current indicator appears in the display.
3. Set the parameters according to your guidelines as described in the chapter "Start up". Check the correctly set output voltage once more.

18. PROTECTIVE MEASURES

The power unit has several integrated automatic protective measures that protect the power unit from damage. The activated protective measures are displayed with letter codes and the DC output is switched off for safety reasons at the same time.

When a protective measures is active, the consumer must be switched off and disconnected from the power unit immediately.

To reactivate the output, switch off the power unit. Wait until all displays have gone out. Switch on the power unit again. The power unit should work normally again. Where this is not the case, please contact our customer service.

The following displays are possible:

a) Over-voltage protection

• A higher external voltage than provided by the power unit was determined at the DC output. The output is switched off.
• The current levels for switching off are listed in the technical data.

b) Overheating protection

• The integrated temperature sensor determined that the system temperature is too high. To prevent overheating, the output is switched off.
• Turn off the power unit and let it cool down for at least 30 minutes. After switching it on, check if the fan or venitlation apertures are blocked. During the start-up self-test stage, the fan must start up audibly. Where this is not the case, please contact our customer service.

c) Overload protection

• In case of overload at the DC output, the power limitation is usually switched on. If this is not the case, the second protective function becomes active.
• Switch off the power unit at once when this warning message appears and check the connection data of the consumer. Remove the consumer from the power unit's DC output.
• Switch on the power unit again and check its function. If the error message remains on, please contact our customer service.

19. MAINTENANCE AND CLEANING

a) General

• Unplug the product from the power source.
• Apart from an occasional cleaning or exchanging the fuse, this laboratory power unit is maintenance free.
• Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chemical agents or detergents containing solvents.
