Safety
If the power supply does not switch ON or if the previous load was larger than 10A, it is possible that
the 10A fuse was blown. Please remove the input power source and check the fuse located under
the input power source connector on the rear of the unit. If the fuse is damaged please replace it
using a high quality fuse which meets the specified requirements (250V, 10A).
Front Output Overheating Protection
The maximum output for the front output is 100VA (V x A) for 2 minutes. The output duration is
longer when the VA is smaller. When VA is less than 25VA, the output is continuous.
If the output value exceeds the specified limits, the output will be placed in STANDBY mode and the
LCD will display “OVERHEATED”. A displayed timer indicates the remaining cooling time that must
elapse before the unit can be switched ON again; When the displayed timer counts down to zero
press the OPER button.
Warning:
Switch the unit OFF within 10 minutes of an overheating condition. The unit
should then be left idle for 5 minutes after power is switched ON.
PC Interface for Data Acquisition
