Input Transient Protection
A metal oxide VDR (Voltage Dependent Resistor) together with the input fuse form an effective protection against high input
voltage transients, which typically occur in most installations.
Input Fuse
An incorporated miniature slow-blow fuse protects the converter
against further damage in the case of a failure.
Reverse polarity applied to the input of CPD models will cause the
fuse to blow but without other damage.
Model Fuse rating Reference
CPA250 250 VAC, 5 A T Schurter 0001.2511
CPA500 250 VAC, 10 A T Schurter 0034.6925
Note:
The fuse is not customer-accessible.
Inrush Current Limitation
The converters incorporate an active inrush current limiter in the input circuitry, which reduces the peak inrush current value
by a factor of 10 – 15 to protect connectors and switching devices from damage.
Note: The inrush current limitation is achieved using electronic circuitry. For effective limitation the converter should not be
switched on and off more frequently than every 8 seconds.
Efficiency
The efficiency graph in the following figure shows the dependence
on input voltage (CPA models).
