CPCL’s New Switch Mode Power Supply (SMPS)

Introduced this summer, CPCL’s Switch Mode Power Supply has been a talking point and is already the subject of multiple orders and approvals. The SMPS converts the available unregulated AC or DC input voltage to a regulated DC output voltage.

Designed and developed specifically for cathodic protection installations, the 144W SMPS can provide stable, accurate outputs of a few millivolts and milliamps up to a maximum of 24V and 6A or 12V and 12A, making it ideal for steel in concrete applications.  It supports simultaneous switching of an unlimited number of units in less than 10 milliseconds, perfect for taking instant off potentials on large systems.  It was also designed to be fully compatible with our Remote Monitoring and Control System (RMCS), allowing it to be controlled over fibre optic, wired and wireless networks on a variety of mobile devices.


With an operating temperature range of -20 to +70 degrees Celsius, the unit can be used in a wide variety of indoor and outdoor locations and is designed and built to meet applicable EMC & Safety Standards and the requirements of BS EN 12696.

The wider benefits of the SMPS include a standardised design that can be adapted to a client’s requirements.  This means that it is a low cost, yet highly efficient, unit with lower running costs.  It is also small in size, allowing for easy configuration of multiple channel systems.
