The SL Power GPM40A is a 40-watt AC/DC converter, part of the GPM40 series, designed for commercial and medical applications. It accepts a wide input voltage range of 85-264 Vac at 47-63 Hz, making it suitable for global use.
This open-frame converter provides three outputs: 5.1V at 4A, 12V at 2A, and -12V at 0.4A, delivering a total continuous power of 40W, with a peak capability of 50W. It offers 70% efficiency at full load and nominal input voltage. Protection features include overload, short circuit, and overvoltage protection on main outputs.
The GPM40A is designed for chassis or panel mounting and operates within a temperature range of 0°C to 50°C. It meets stringent EMI standards, exceeding FCC Class B and CISPR 22 Class B for commercial models and CISPR 11 Class B for medical models. Approvals include UL, CSA, and CE.
Key electrical specifications include a minimum hold-up time of 20 ms, a turn-on time of less than 1 second, and a temperature coefficient of 0.03%/°C. The unit also features adjustable output voltage (±5%) and remote sense on single-output models.
0°C to 50°C at full rated output power, derate 2.5% per °C above 50°C.
Output 1: 5.1V at 4A, Output 2: 12V at 2A, Output 3: -12V at 400mA.
85-264 Vac, 47-63 Hz single phase.
Overload protection (short circuit and overload), overvoltage protection (124%±12% on main outputs), internal AC fuse.
70% at full rated load, nominal input voltage.
127.0mm x 76.2mm x 32.5mm (5.00" x 3.00" x 1.28").
Conducted emissions: FCC Class B, CISPR 22 Class B (commercial) or CISPR 11 Class B (medical). Also meets EN61000-4-2, -4-3, -4-4, -4-5, and EN61000-3-2.
