Safety
(Fail-Safe Function)
For safety, the switching operation is stopped (output off status)
and the AC power relay is interrupted while a protection function
is operating.
●
Output over-voltage protection (OVP)
When the output voltage exceeds the OVP setting value, the
switching operation (oscillation) is stopped and the output is
turned off.
●
Output over-current protection (OCP)
Increase in the output current to 110% or more of the rated current
is detected by a protection circuit, which stops the switching
operation and interrupts the AC power relay.
●
Over-heat protection (OHP)
When the heat sink temperature reaches about 100
℃
, the
switching operation is stopped and the AC power relay is
interrupted.
●
Input power abnormality protection
In case of input over-voltage, input voltage drop or an over-current
due to internal abnormality, the switching operation is stopped
and the output is turned off.
●
Alarm (power abnormality) signal
When the output over-current, input over-voltage or input over-
current is detected, when the over-heat protection circuit is
activated or when the power is switched off, an alarm signal is
generated to turn the output off and interrupt the AC power relay.
●
Power relay off signal
When trouble occurs on the user side, etc., the power relay is
interrupted by an external signal.
(Rush current protection circuit)
The rush current protection circuit is activated at the moment of
the power is switched on to reduce the input surge current.
GP-IB System Compatibility
In addition to the output voltage and current control capabilities
and status signal outputs, the output on/off, power on/off control
and remote/local switches are provided. The GP-IB control is also
possible optionally (when the optional GP-600 is combined.)
Wide Applications
Control operations include control by an external voltage or
resistance of the output voltage and current.
Low Noise
The temperature-sensitive fan motor reduces the rotation speed
when the load is light or the ambient temperature is low to prevent
noise.
Front Air Intake
The forced air cooling system intakes air through the front panel
and increases the packing density in case the power supply is
mounted in a device or rack. The front grill incorporate an air filter
to improve dust protection.
