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.

Optional Coating (option C): We offer the CPS-EC series with an optional coating. It is to be used in e.g. dusty, dirty, high humidity area or in awaiting quick temperature changes. Short circuit and corrosion at print board lines and at solder points can be prevented. The coat itself is a transparent acrylic resin.
