Open frame power supply TPS-GSH600S

AC/DCsingle-outputwith overload protection

Product overview
The TPS-GSH600S-48V is a single-output open-frame power supply from the TPS-GSH600S series with an aluminium enclosure. It supports wide AC and DC input ranges for global use and offers two cooling-dependent power ratings: 320 W by natural convection and up to 600 W with forced-air cooling (25 CFM). The unit provides a nominal 48 V output (adjustable 44–54 V), Active PFC, LED status indicator and a remote sensing terminal. Isolation voltage is 3750 VAC and operating temperature range is -25 °C to +70 °C.
