Technical Concept
The Camtec HSR03201 series is a high precision switch mode power supply for an upscale demand. The unit
is voltage adjustable. It is engineered and manufactured by CAMTEC in Germany. The designed meets
challenging applications like railway, complex drives, battery charging for DC-UPS, test-stands, machine-
building and infrastructure projects. The power supply provides a low ripple-noise, a precise load-regulation and
high efficiency up to 91%. High-end long-life capacitors guarantee an extended hold-up-time and an
extraordinary lifetime of the power supply. The circuit design starts complex loads easily. The internal control
circuit manages illegal operating conditions to prevent your system from damages. The HSR series features
active high input transients with suppressor diodes, X2-capacitors and varistors. All inputs, outputs and feature
connections are galvanic isolated. The design rules set value on extended interference immunity and safety.
The unit is designed in accordance to the EN60950-1 and the EMC-compatibility to EN55022. Our engineering
design is made in accordance to the CSA/UL60950-1 and the IEEE CB scheme rules.
Overtemperature, Over Voltage Protection & Derating
OT Over Temperature
The maximum ambient temperature is +70°C. There is
temperature protection inside the power supply. When the temperature exceeds
a certain level the HSR03201 will be shut down. The unit provides an automatic
restart
when
the
temperature
returns
to
applicable
conditions.
OVP Over Voltage Protection
Exceeding the OVP results into ticker mode.
Resuming the failure causes automatic restart into normal operation.
DC-OK (Power Good Relay)
The DC ok relay indicates if the output voltage is low. The contact is galvanic insulated to
the AC input and the DC output connections. The isolation covers the overall adjustment
range of the HSR03201 series up to 60Vdc. If the DC voltage is ok the relay is closed. If the
power supply unit is in false operation the relay is open.
C/V Current Voltage Behaviour
The HSR03201 series provides a good current voltage chart. It has no fold back or other abnormalities. The
output voltage can drop down to zero volts when the power supply is overloaded. The unit delivers a stable and
constant current to the outputs. When the output voltage is set to the maximum demanded value and the
current limit reaches its margin, the output voltage drops down and the unit delivers constant current.

Parallel Operation & Decoupling
T
o
increase the overall power of the power supply, two or more devices of the same model with the same
output voltage may be operated in parallel. To avoid any issues, make sure the cable lengths and cable cross-
sections of all power supplies to the star point are identical.
