Bel Power Solutions W series of convert-select front ends represents a family of DIN-rail mountable DC-DC and AC-DC converters with power factor correction and low harmonic distortion. They have been designed according to the latest industry requirements and standards, available with a single output or two independently regulated, electrically isolated outputs.

The input has a negligibly low in-rush current, high immunity to transients and surges, and low electromagnetic emissions. Internal protection circuits such as input over- and under-voltage lockout, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system. The outputs deliver an electrically isolated Safety Extra Low Voltage (SELV) and low output noise.
