A highly reliable, variable DC Bench Power Supply with built in short circuit and thermal protection.
It meets CE certification requirments.
Input Voltage is 220-240VAC and the unit comes with a UK 3-pin power lead.
We supply EU adapters free of charge with continental European orders.
This is a linear unit, not a switch mode supply
The power supply unit is equipped with protection circuits that protect the units from short circuits and over temperature by shutting down for safety.
It features independent serial and parallel mode operation.
This power supply is suitable for the laboratory, electronics, communications equipment maintenance, production line, scientific research and educational institutions.
This bench power supply functions in series or parallel modes for great flexibility.
Ships with a set of 4mm banana plug leads. Bare wires can also be attached by unscrewing the connection ports and affixing wires to the binding posts. .

Guidelines for Operation
To use in Constant Voltage Mode (normal operation)
Set the C.C. adjustment to MAX, so that no current limiting occurs.
Set Voltage as desired.
Output can then be set.
NB: Current will be shown on the display only when a load is connected.
Using the Current limit to Control Output:
Switch ON the power WITH NO LOAD CONNECTED.
Rotate the C.V. dials clockwise to MAX.
Rotate the C.C. dials counterclockwise to MIN.
NOW connect the required load.
Rotate the Current control dials until the output Current reaches the required current value.
The C.V. indicator will be off and the C.C. indicator will illuminate.
To set a current limit for use during normal operation:
Turn power “ON”.
Select a low Voltage (e.g 0.1V).
Turn the C.C. adjustment to MIN.
Then connect the positive and negative output terminals to create a short circuit.
This puts the unit in 'C.C. set mode'.
Rotate the C.C. dials clockwise until the desired output current is shown on the display.
Now disconnect the short. The CC setting is set until the unit is next powered “OFF”.
At next switch on the unit defaults to the current value determined by the last position of the current dials.
