CPS-EC1500 SERIES

Product Overview

CAMTEC - CPS-EC1500 SERIES 

1500W 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 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.
