Input Fuse and Reverse Polarity Protection
A metal oxide varistor (voltage dependent resistor VDR)
together with the input filter form an effective protection
against high input voltage transients, which typically occur
in most installations.
An incorporated fuse protects the converter against further
damage in the case of a failure.
Table 3: Fuse specification
To avoid unwanted power losses, the CPD200/250 models
are not protected against reverse polarity at the input by a
serial diode, but only with an antiparallel diode. In the case
of reversed input voltage, the input fuse will blow; however
no further damage will occur.
The CPD500 models are protected against reverse polarity
by a special circuitry, which generates no losses. The
converter will simply not start-up, but no damage will occur.
The CPA Series converters are designed for AC input and
have a rectifier bridge on the input.
Input Current Limitation
All converters incorporate an active inrush current limiter in
the input circuitry, which reduces the peak inrush current
value by a factor of 10
switching devices from damage.
Input Undervoltage Shutdown
CPD200/250 models start at approx. V
input voltage is applied; at decreasing V
approx. 21 V.
CPD500 models start at V
CPA models exhibit an undervoltage trigger controlling
start-up and shutdown. The threshold is between 80 and 90
VAC. See also Power Fail Signal.

Note: The fuse is not customer-accessible.
Note: The inrush current limitation is achieved using an
electronic circuitry. For effective limitation the converter
should not be switched on and off more frequently than every
8 seconds.
