Code: EPU0113

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.

By connecting an ac power source to one of the coils and reading the voltage from the other coil transformer action (either step up or step down) may be readily demonstrated. The efficiency of the transformer may be studied –does the efficiency change if the laminate top is not firmly fixed? What happens if it is not present? Other more esoteric effects such as Magnetostriction may also be studied.
Pack of 10 24V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
Our additional Pylons pack contains 5 thick card sheets which once cut-out produces 5 pylons to be used in conjunction with our National Grid Kit to give your pupils a clearer explanation on how the experiment works.
