The SL Power Electronics GPM225-24 is a 225 Watt Global Performance Switcher designed for commercial and medical applications. This open frame AC/DC converter operates with a wide input voltage range of 85-264 Vac and provides a convection-cooled output power of 175W, which can be boosted to 225W with forced air.
Key electrical specifications include a maximum input current of 5.5A at 120 Vac, a hold-up time of 20ms, and overload protection against short circuits. It offers overvoltage protection at 124% ± 12% typical and an efficiency of 70% at full load. The unit includes internal AC fuse protection and inrush current limiting.
Designed for reliability, the GPM225-24 features thermal shutdown and a temperature coefficient of 0.03%/°C. It operates from 0°C to 50°C at full rated power, with derating above 50°C. The power fail signal is TTL- or CMOS-compatible, indicating voltage drop before AC power loss.
This converter is suitable for medical applications and meets various compliance standards. It is chassis mounted and has dimensions of 228.6mm x 127.0mm x 63.5mm. Features include adjustable output, remote sense, and universal input.
The input voltage range is 85-264 Vac, 47-63 Hz single phase.
The operating temperature range is 0°C to 50°C at full rated output power, with derating above 50°C at 2.5% per °C.
The output power is 175W convection, 225W with 26 cfm forced air, and 250W peak (60s max, 10% duty cycle).
It includes overload and short circuit protection (cycling type, automatic recovery), overvoltage protection (124% typical), and thermal shutdown.
The dimensions are 228.6 mm (9.00") length, 127.0 mm (5.00") width, and 63.5 mm (2.50") height.
It meets EN55011 Class B and FCC Class B for conducted emissions, and EN61000-4-2 static discharge (6 kV contact, 8 kV air).
