The SL Power Electronics GPM55C is a 55 Watt Global Performance Switcher designed as an AC/DC converter. It features an open frame construction and chassis mount type, making it suitable for various integration needs.
This converter operates with a wide-range AC input from 85-264 Vac and provides up to 55W of continuous output power, with a peak rating of 70W. It includes four outputs and offers features such as adjustable output voltage on outputs 1 & 2 and universal input.
The GPM55C is designed for demanding applications, including medical equipment, with approvals to relevant safety standards. It meets EMI/EMC compliance requirements, including FCC Class B and CISPR 22 Class B.
Key specifications include an efficiency of 70% at full load, a typical operating temperature range of 0-50°C with derating above 50°C, and protection against overload and short circuits. The unit dimensions are 160.0mm x 100.0mm x 42.7mm.
The input voltage range is 85-264 Vac at 47-63 Hz.
Continuous output power is 55 W, with peak capability of 70 W for up to 60 seconds at 10% duty cycle.
It includes overload protection (cycling type on outputs 1&2, foldback on outputs 3&4, factory set to limit at ~75 W) and overvoltage protection on main outputs at 124% + 12%.
The operating temperature range is 0°C to 50°C at full rated output power, with derating of 2.5% per °C above 50°C.
The dimensions are 160.0mm x 100.0mm x 42.7mm and it is designed for chassis mount.
It holds commercial approvals UL1950, IEC950, CSA22.2-234 L3 and medical approvals UL2601-1, IEC601-1, CSA22.2 No. 601.
It meets EN55022 Class B, FCC Class B, EN55011 Class B for conducted emissions, and immunity standards EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, plus EN61000-3-2 Class A for harmonics.
