The SL Power Electronics GPM55-12G is a 55W AC/DC converter designed for reliable power conversion in various applications. It provides a single 12V output with a continuous current rating of 4.7A and a peak rating of 70W for short durations.
This converter operates with a wide input voltage range of 85-264 VAC, making it suitable for global use. It features adjustable output voltage (±5% on outputs 1 & 2) and a typical efficiency of 70% at full load. The unit includes built-in EMI filtering to meet FCC Class B and CISPR 22 Class B standards.
Designed for chassis mounting, the GPM55-12G has an open frame construction. It operates within a temperature range of 0°C to 50°C at full rated power, with derating required above 50°C. The converter is protected against overload and short circuits, with automatic recovery after a fault.
Key specifications include a hold-up time of 20ms minimum, a transient response time of 500μs typical, and low output noise (0.5% rms, 1% pk-pk). It is approved by CE, cURus, and TUV, and complies with various safety standards including UL1950 and IEC601-1 for medical applications.
