The SL Power Electronics GPM225-28 is a 225 Watt Global Performance Switcher, specifically an open-frame AC/DC converter designed for chassis mounting. It operates with a wide-range input of 85-264 VAC and provides 175W of convection-cooled power, expandable to 225W with forced air.
This converter is engineered for reliability, featuring overload and short circuit protection, overvoltage protection, and thermal shutdown. It offers a 7A output current and includes features like adjustable output voltage (±5%) and remote sense capabilities. The unit is designed for operation between 0°C and 50°C, with derating above 50°C.
Compliance is a key aspect, with conducted emissions exceeding FCC Class B and CISPR 22 Class B standards. It holds commercial approvals to UL1950, IEC950, and CSA22.2-234 L3, and medical approvals to UL2601-1, IEC601-1, and CSA22.2 No. 601. Its wide-range input and robust protection make it suitable for various industrial and medical equipment.
The physical dimensions are 228.6mm x 127.0mm x 63.5mm (9.00" x 5.00" x 2.50"). The power fail signal provides an early warning before AC input loss, enhancing system stability. This model is part of the GPC225 Commercial/GPM225 Medical series.
85-264 VAC single phase, 47-63 Hz.
