Open frame power supply TPS-GSH450S-12V

AC/DCsingle-outputswitching

TPS-GSH450S-12V Power Supply The TPS-GSH450S-12V is a high-performance Single Output Open Frame Power Supply in the TPS-GSH450S Series, featuring an aluminum enclosure and a compact 5×3 inches design (L×W×H: 127x76.2x28mm). It supports 85-305VAC and 120-420VDC input, adapting to global power grids. As a 250W natural convection power supply, it delivers 250W under natural convection; with 12V 20CFM fan cooling, it functions as a 450W forced convection power supply, providing up to 450W output. Operating in a -25℃ to +70℃ range, it ensures stable performance, featuring 3750VAC isolation voltage for safety, active PFC function to optimize power factor, and LED indicator for status monitoring. As an output voltage adjustable power supply, its range is 11.4~12.8V. With high efficiency up to 95.5% (91%/93.5% at 115VAC/230VAC typically), it includes comprehensive protection: input undervoltage, output overvoltage, overcurrent, output short circuit, and overtemperature protection. Suitable for industrial automation, industrial control systems, communication equipment, LED systems, smart home devices, electronic instruments, and medical equipment, it meets diverse application needs.
