Description

This series of high current, fixed voltage, regulated switching mode power supplies are built with, Over Voltage Protection for safe-guarding voltage sensitive load. High efficiency cuts the running cost and active Power Factor Correction (PFC) maximizes the main's available power.

They are suitable for applications in telecommunications such as radio equipments, RF amplifiers, and other high current applications like car audio, halogen, xenon spot light demonstrations.

The high grade Screw On output terminals are on the back panel of the console while the power on off switch and the bi-colour LED indicator (Power On /Overload) is at the front. The variable speed thermostatic control cooling fan ensures quiet operation of the power supply in medium load condition.

The small size console fits well with the footprints of most modern telecom equipments.
