DIN-rail Power Supply from PULS Power Features Integrated LED Display

July 9, 2021

The new CP20.248 extends PULS Power’s product portfolio by adding a 24V, 20A 1-phase DIN-rail power supply with an integrated display. The LED display means a reliable and inexpensive condition monitoring feature can be integrated into almost any system allowing users to benefit immediately from faster fault diagnosis and increased system availability.

The display shows important status information about the power supply for commissioning and maintenance and can display real-time information and recorded data. The real-time data supplied by the CP20.248 includes the input and output voltage, output current, operating hours and temperature inside the device.

The recorded data gives users insight into the number of transients on the input side as well as minimum and maximum voltage and temperature values fand more. This information can help the system engineer optimise an entire application in terms of reliability and to identify the cause of faults or errors more efficiently. The display and data storage have an independent power source ensuring that all the information is still available, even if the power supply fails.

For remote status monitoring two relay contacts for DC-OK and alarm signals are provided. Two additional inputs allow the power supply to be put into an energy-saving standby mode using the remote ON / OFF function and automatic load sharing in parallel operation for greater power output can be realised. Parallel operation ensures an optimised temperature balance between the connected power supplies, prolonging the service life of the devices.

All CP20 versions share the same compact housing with dimensions of 48x124x127mm, which includes the space required for the integrated display. This is made possible by a very high efficiency of 95.6%. As a result of the low power losses, less heat is generated in the housing and the clearance and creepage distances can be reduced.

The PULS CP20 has an operating temperature range from -25 to +70°C, 50% extra output power for up to 5s, has fully international safety agency approvals and a three-year warranty.

Applications for the PULS CP20 include industrial systems and machine building, SMART buildings and factories, Industry 4.0, security and CCTV, instrumentation and measuring systems.
