POWER SUPPLY, AC / DC, 0-13V (0301)
The unit provides AC and DC voltages in 1 V steps up to 13\1. The AC is full wave rectified to give the DC equivalent. AC available through a pair of yellow 4mm shielded sockets, whereas DC through a pair of colour coded sockets. Protection against electrical overload or short circuit is provided by a thermal circuit breaker. When the rated current is exceeded, the circuit breaker opens and an audio signal is emitted. On removal of overload condition, the audio signal stops and power is returned within one minute. Rotary voltage selectors on the front panel determine the AC and equivalent DC voltage output. Complete unit housed in a sturdy sheet metal casing. With indicator type ON/OFF switch. Mains Input 220-240V AC, 50Hz, Voltage Output AG - O to 13V (nominal) in 1 V steps; DC - full wave Rectified equivalent of selected AC voltage, Current Output Primary Maximum 5A, Protection Secondary 2A time delay fuse, Protection : Thermal circuit breaker, self re-settable.
