Volt Lock Power Supply

A compact, general-purpose power supply offering 2, 4, 6, 8, 10 or 12V ac/dc at up to 5A. Voltage selection is via a key switch. The voltage may be set to any voltage and the key removed to prevent tampering. A common key profile is used for all units so the teacher only requires one key to operate all units. Both ac and dc outputs may be used simultaneously up to the rated current (5A).

Fitted with automatically resetting thermal cut out to protect against overloading or short circuits. Actual d.c. voltage is read on a digital display which demonstrates a voltage drop with increasing load. Combined fuse holder (2A mains fuse), switch and IEC connector. Four units fit into a Gratnells shallow tray for easy storage and transport.
