Calex – 50 Watt 4:1 Encased DC/DC Converters (SBMQ12 Series)

The world of “brick” DC-DC converters has seen a steady size reduction. The SBM series makes another dramatic size shrink down to a “sixteenth brick” width (1.04 inches) while still retaining a high power output and full 2828 Volt DC isolation.

The converter family accepts 9 to 36 Volts DC inputs and delivers fixed outputs regulated up to within ±0.125%. The SBM converters are ideal for industrial and railway applications, datacom and telecom applications, cell phone towers, data centers, server farms and network repeaters.
