The unit has 1 output display. The display has 2 readings. The left is Current and the right
is Voltage. There is 1 output That is 0-30 Volts with 0-3A.
This unit fan turns on when the temperature reaches 115 DegF or 50 Deg C.
It takes a standard 220VAC input only. And it is fuse protected.
2. Attention:
2.1 The mains power must be switched off before servicing and servicing should be
referred to a qualified person.
2.2 The unit should be stored in a dry and well ventilated place and the power cord should
be removed from its power source for long periods of inactivity.
