Overview Asterion DC Series
1-20
1.2.15 Protection Function Characteristics
Function Characteristic
Output Overvoltage Protection
(OVP)
Programmable to 110% of full-scale output voltage;
exceeding OVP threshold results in shutdown of output.
Output Current Limit Protection
User-selectable fold back mode CV/CC/CP or CV or CC or CP
models.
In CV/CC/CP mode, output current or power is regulated to
setpoint on reaching limit.
In CV mode, on reaching current or power limits results in
shutdown of output;
In CC mode, on reaching voltage or power limits results in
shutdown of output;
In CP mode, on reaching voltage or current limits results in
shutdown of output;
In CV or CC or CP mode, shutdown delay on reaching the limit is
programmable from 100 ms to 5 s.
AC Input Overcurrent Protection
Internal fuses in each phase for fault isolation; not user
replaceable
AC Input Undervoltage Protection Automatic shutdown for insufficient AC input voltage
AC Input Transient Protection Protection to withstand EN61326-1, Class-A surge levels
Overtemperature Protection (OTP)
Internal temperature monitors cause shutdown of output if
temperature thresholds are exceeded
