AC-DC and DC-DC Converters
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.
Note: The fuse is not customer-accessible.
Efficiency
The efficiency is specified in table 1. Its dependence upon the
input voltage V i is shown in fig. 2a (CPA models) and fig. 2b
(CPD500 models). The efficiency of CPD200/250 models
depends only marginally upon V i .

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

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.

Input Undervoltage Shutdown
CPD200/250 models start at approx. V i = 22 V, when the input
voltage is applied; at decreasing V i , they switch off at approx.
21 V.
Note : The input current I i may exceed I i max , if V i ≤ V i min .
CPD500 models start at V i = 35 V and switch off at V i = 33 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 : CPA200/250 with version ≤ V116 should not be operated
at V i ≤ V i min , as these models have no undervoltage shutdown
and will therefore operate with a high input current at full load.
