Open frame power supply TPS-GSH750S-24V

AC/DCsingle-outputregulated

Product overview
The TPS-GSH750S-24V is an open-frame single-output power supply from the TPS-GSH750S Series with an aluminum enclosure (127×76.2×40 mm). It accepts wide input ranges (85–305 VAC / 120–420 VDC) and delivers 500 W in natural convection (24 V / 20.84 A) or up to 750 W with forced-air cooling using a 25 CFM fan (24 V / 31.25 A). The unit operates from −25 °C to +70 °C, provides 3750 VAC isolation and reaches up to 95% efficiency under specified conditions. Designed for industrial and professional applications requiring CC+CV output and remote sensing.
