This premium digital power supply features AC overload cut-off with a resettable switch and overload protection. The unit provides three independent DC output voltages, one selectable AC output, an overload protection indicator, and glass fuses at the input level. An instruction and safety manual is included. The DC outputs provide high voltage (0-500V at 10 mA and 0-80V at 10 mA) and low voltage (0-20V DC at 5A). The AC output is selectable from 1-6V AC at 2A via an A/V selector switch, provided on four different sockets. All outputs are independent and can be used simultaneously. The unit operates on 110/120V AC, 60 Hz and 220/240V AC, 50/60 Hz using a voltage selector switch.
