Intended Use

The laboratory power unit unit serves as a potential-free DC voltage source to operate low-voltage consumers. It has three adjustable independent outputs. The outputs A and B can be switched with each other and controlled via buttons. This easily allows you to double the voltage or current. When switching the outputs in series, voltages of >75 V/DC may be generated, which are dangerous to contact. This is why insulated lines/measuring cables must be used for safety reasons as of this voltage. The devices are connected via 4 mm safety sockets.

The output data of the laboratory measuring devices is as follows:

Item No.Item nameOutput AOutput BOutput C
512773 VSP22060.1 - 20 V/DC0.1 - 20 V/DC0 - 6 A 0.1 - 6 A max. 1.5A
512774 VSP24030.1 - 40 V/DC0.1 - 40 V/DC0 - 3 A 0 - 3 A max. 1.5A
512775 VSP24050.1 - 40 V/DC0.1 - 40 V/DC0 - 5 A 0 - 5 A max. 1.5A
511919 VSP24100.1 - 40 V/DC0.1 - 40 V/DC0 - 10 A 0 - 10 A max. 1.5A
512776 VSP26530.1 - 65 V/DC0.1 - 65 V/DC0 - 3 A 0 - 3 A max. 1.5A

The voltage and electric current can be adjusted continuously for outputs A and B, as can the voltage of output C. The voltage and current values of output C are displayed via the push of a button on the display of output B.

The settings for current and voltage are made via coarse and fine controls in order to allow fast and precise value settings.

The values are displayed on two separate, concise LC displays.

The output voltage of outputs A and B can be set through an external voltage and kept absolutely stable and load independent using the sense function.

A power limit for constant power operation can be pre-set by pressing a button. You do not require a shorting bar at the output during setting.

The device is overload and short-circuit-proof and contains a safety temperature cut-off.

The laboratory power unit is designed in compliance with protection class 1. It is only approved for connection to shockproof sockets with protective grounding and an alternating current of 230V/AC commonly used in households. The ground potential socket is directly connected with the protective grounding on the mains plug.

Operation under adverse environmental conditions is not permitted. Unfavourable ambient conditions are:

  • Moistness or high humidity
  • Dust and combustible gases, vapours or solvents
  • Thunderstorms or similar conditions such as strong electrostatic fields etc.

Any use other than the one described above damages the product. Moreover, this involves dangers such as e.g. short circuit, fire, electric shock, etc. No part of the product must be modified or rebuilt!

Observe the safety instructions under all circumstances!

Functional Description

The laboratory power unit works with highly developed combinational circuit technology and active PFC (power factor correction). This ensures a stable output voltage and a high degree of effectiveness. The DC outputs are electrically isolated and feature a protective isolation towards the mains voltage. The secondary DC connection is effected via two coloured safety sockets.

The concise dual displays show the voltage and current separately for outputs A and B (V = Volt = unit of electric voltage, A = Ampere = unit of electric current). Output C is displayed via a button on the display of output B. Via light displays the current condition of the power unit is indicated. Various protective mechanisms, e.g. overload protection, current limitation, overheating protection, etc. are built in for secure and reliable operation.

The cooling of the power unit is provided via integrated ventilators. Therefore, ensure sufficient air circulation.

The power unit can set the output voltage and the output current continuously (with output C the voltage only).

Commissioning

VOLTCRAFT VSP 2405 - Commissioning - 1

The laboratory power unit is not a charger. To charge batteries, use suitable chargers with a charging current cut-off.

During a longer period of operation under nominal load, the surface of the housing will heat up. Attention! Risk of burns! Therefore, make sure that there is adequate ventilation of the power unit and never operate it partly or fully covered to avoid damage.

When connecting a consumer ensure that it is not connected when switched on. A switched on consumer can result in sparks when connecting to the output terminals of the power unit, which in turn can damage the sockets or the connected cables and/or their clamps.

If your power unit is not required, disconnect it from the mains.

Connecting the power cable

Connect the supplied grounding mains cable to the low-power device installation socket (27) on the power unit. Ensure a tight fit.

Connect the power cable to a shockproof mains socket with protective grounding.
