Description
The Camtec CPS-EC series is a high precision switch mode power supply for an upscale demand. The unit is
C/V 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
professional LED lighting. The power supply provides a low ripple-noise, a precise load-regulation and high
efficiency up to 92%. 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 CPS-EC 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 class B norms.
Our engineering design is made in accordance to the CSA/UL60950-1 and the IEEE CB scheme rules.
Voltage Setting Potentiometer
The output voltage limit can be adjusted with a 15 turn high precision
potentiometer. The listed values are guaranteed by the factory. The
tolerance of the upper margin is -0/+5%. The tolerance of the lower
margin is -5%/+0%. The output voltages cover the typical cell voltage
range of standard lead acid batteries.
Current Setting Potentiometer
The output current limit can be adjusted with a 15 turn high precision
potentiometer. The listed values are guaranteed by the factory. The
tolerance of the upper margin is -0/+5%. The tolerance of the lower
margin is -5%/+0%.
Sensing
The device has a sense operation mode to compensate a voltage drop at
the load line.
Inhibit contact (Interlock)
The inhibit inputs can be connected to a safety contact or a safety relay.
When the contact is open the power supply will remain in a completely
locked shut down mode. The unit powers up as soon as the contact is
closed.
External Shutdown feature
All CPS-EC units are featured with a shutdown (open collector).
DC-ok Power Good Relay
The PG Relay connection indicates over temperature, low DC-voltage at
the output, low AC supply voltage at the input, the inhibit and the shutdown
mode.
Galvanic Isolation
The power supply is galvanic isolated between the input and the output. All
features like Shut Down, Inhibit, Power Good Relay, Sensing and the Current
Monitoring are connected to the DC power outputs.
Thermal shutdown
The CPS-EC series is featured with a thermal overload shut down and auto
recovery behaviour.
