The IEC 'Selectavolt' Power Supply is a small unit with a slide switch on the rear panel to select regulated output voltages of 1.5V, 3V, and 6V.DC. at 2A continuous or 3A intermittent. There are no AC outputs. The regulated outputs are smooth DC and it is designed to simulate dry cell batteries. 4mm sockets on the rear panel permit the trickle charging of NiCd cells from 1.5V to 6V. Output is via 4mm spin free IEC terminals.
