CPS-EC480 SERIES

Product Overview

CAMTEC - CPS-EC480 SERIES 

480W Precision DC Rectifier,  

DIN-Rail Battery Charger, C/V Adjustable Industrial Power.  

Available Outputs:   24V,  36V,  48V,  60V,  72V,  110V,  150V,  220V,  300Vdc  

Description   The CPS-EC power supply series realizes very high power efficiency in a space-saving housing. Latest generation electrical devices relate to the high reliability of all CAMTEC products. The CAMTEC philosophy is, to employ 125°C low ESR ultra long life capacitors where expedient to achieve a superior lifetime of the product. The CPS-EC power supply is made for high reliable and demanding industrial applications, rail way, unbreakable power supply charger (DC-UPS), professional high power lighting (floodlight, production hall) and for telecom & demanding IT applications.

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%.

Output Current Monitoring   The CPS-EC power supply features a 0-5Vdc signal output. It is a realtime linear signal and indicates the current consumption of the load. The measuring point is directly at the output connection of the device.

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.
