The Mean Well RT-125C is a 133W enclosed AC/DC converter with three independent outputs: +5V (12A), +12V (5.5A), and -15V (1A). It operates from a universal AC input range of 100~240VAC at 47~63Hz. The converter achieves up to 81% typical efficiency at 230VAC and maintains tight regulation across channels.
Protection features include overload protection at 110~150% rated output power (hiccup mode auto-recovery) and over voltage protection (hiccup mode, auto-recovery after fault removal). The unit is rated for operation from -25°C to 70°C with derating above 50°C, and can be stored at -40°C to 85°C. The MTBF is 209.3Khrs minimum per MIL-HDBK-217F at 25°C.
The RT-125C measures 199.0 x 98.0 x 38.0 mm and meets safety standards UL60950-1 and TUV EN60950-1. It complies with EN55022 Class B (CISPR22) for conducted and radiated emissions, as well as EN61000-3-2,-3 for harmonics. Immunity complies with EN61000-4-2,3,4,5,6,8,11 and EN61000-6-2 at heavy industry level, criteria A.
The input voltage range is 100~240VAC at 47~63Hz.
Channel 1: 5V at 12A; Channel 2: 12V at 5.5A; Channel 3: -15V at 1A.
It is approved to UL60950-1 and TUV EN60950-1.
The operating temperature range is -25°C to 70°C with derating.
Yes, overload protection is set to 110~150% of rated output power with hiccup mode auto-recovery.
Typical efficiency is 81% at 230VAC.
Dimensions are 199.0mm (length) x 98.0mm (width) x 38.0mm (height).
