This document is about the specification of MPS-120 model, including input voltage, input current, inrush current, setup time, hold-up time, leakage current, DC output voltage adjustment range, overload protection, overvoltage protection, power good / fail signal etc.
The MW 120W Medical Series is a universal‑input AC‑DC power supply designed for medical equipment. It offers 1‑4 output channels, low leakage current (<180 pA), and multiple protection features such as short‑circuit, overload, and over‑voltage protection. The series complies with UL60601‑1, TUV EN60601‑1, and IEC60601‑1 medical safety standards and includes optional power‑good/fail signaling.
Key electrical specifications include an input voltage range of 90‑264 VAC (47‑440 Hz) or 127‑370 VDC, maximum input current of 2.9 A at 115 VAC, and inrush current under 22 A (115 VAC) or 45 A (230 VAC). The units operate from –20 °C to 70 °C, tolerate 20‑90 % RH, and feature >100 MΩ isolation resistance. Mechanical dimensions are 177.8 × 107.95 × 35.5 mm, with Molex connectors for AC input and DC output.
