A solid general purpose power supply giving 2, 4, 6, 8, 10 and 12V ac/dc at up to 8A continuous. Apart from our standard automatic short circuit protection, the unit contains a unique electronic locking system. By inserting a screwdriver into a slot on the underside of the case, the maximum available output voltage may be limited. The maximum output is clearly displayed on a bank of leds on the front panel. ac or dc is available through two pairs of terminal posts - ac/dc selection is made via a removable key.
Westminster Power Supply 57.75
This unit will deliver up to 12A ac or dc through colour coded terminal posts. Ideal for electromagnet investigations.
Simultaneous use of ac and dc up to 5A continuous. Short term current up to 7A. Safety features include a keyswitch which inhibits voltages above 6V. Housed in a rugged steel case.
2 models - the 2-12V has a push button reset and the 1-12V has an internal, solid state cut-out.
5A ac/dc 2-12V, 2V steps £91.77
5A ac/dc 1-12V, 1V steps £101.85
6A ac/dc Keylock £108.15
Voltage selection is via a removable key - the key is a common profile type allowing one key to operate all the power supplies. 2, 4, 6, 8, 10, 12V ac and 1, 3, 6, 8, 11 and 13V capacitor smoothed dc. Simultaneous use of ac and dc up to 6A continuous. Sophisticated overload/short circuit trip which isolates the output under fault conditions and gives an audible/visual alarm.
A compact power supply offering 2, 4, 6, 8, 10,and 12 volts at currents of up to 5A. Both dc and ac outputs may be used simultaneously up to the rated output. The output is protected by a push button cut-out. The unit is 2A fused on the back panel and comes complete with a moulded mains lead and plug.
4 units are designed to fit in a shallow Gratnell tray.
Similar to the above unit but voltage selection is made using a keyswitch. The key may be removed in any position. This makes it impossible for a student to alter the voltage. A single profile key is used which means that one key can be used to operate all the units. Comes supplied with two keys.
