The SMC20 supplies 12V equipment from a 24V system, stepping the voltage down from 24V to 12V at up to 20A continuous (276W). High efficiency and a compact housing make it well suited to higher-draw auxiliary loads.
The high-efficiency switching technique allows a smaller housing, and the unit is short-circuit protected and current limited throughout. Running at around 90% efficiency, it combines high efficiency with great reliability. UK manufactured.
