Alarms
The power supply has a protection function. When the protection alarm is set, the protection
mechanism will be triggered and respond accordingly when the set conditions are reached.
OVP
The overvoltage protection (OVP) function prevents
the load from being damaged by high voltage and
triggers the output to be disconnected.
OCP
The overcurrent protection (OCP) function prevents
the load from being damaged by high current and
triggers the output to be disconnected.
OTP
Overtemperature protection function can prevent the
instrument from overheating damage and
automatically disconnect the output.
Alarm output
The alarm output is a separate open collector
photocoupler output. When the protection settings
(OCP, OVP, OTP) are exceeded, the power supply
will automatically shut down and an alarm will be
output via the analog control interface.
Considerations
The following conditions should be considered when using SPS power supplies:
Inrush current
The power supply generates an inrush current when it is turned on. Ensure that the power
supply is sufficient at the moment of starting, especially when multiple power supplies are
turned on at the same time.
