This unit is equipped overcurrent protection and output current is
limited about 110% of rating and the power supply and the load are
protected at overload.
This unit is equipped overvoltage protection and output voltage is
limited about 110% of rating and the load is protected at abnormal.
This unit is equipped two kinds of eddy current protections,
high speed eddy current protection circuit to limit pulse current
and overcurrent protection circuit to limit stationary current.
The above mentioned overcurrent protection is to limit stationary
current and its response speed is about 1msec. Another circuit
to limit current of high speed response type is added separately
and it restricts pulse current to about 2 times of rating at
rectangular wave or capacitive load.
This unit is a bipolar power supply possible to operate in four-quadrant behavior. It is able to source or sink current in the ranges as shown
on the following figure.
