Universal input range DIN rail mount AC-DC power supply for 12Vdc convection cooled industrial applications

Universal input DIN rail mount AC-DC power supply for 12Vdc, convection cooled industrial applications
The MIW 100-U/12-F0PD-HF AC-DC power supply delivers up to 100W output power. The unit accepts a wide, universal input range of 95V to 264Vac, which allows the unit to be used in multiple regions with different voltage standards and ensures stable operation across a wide range of input voltages. The unit provides 12Vdc at 8.4A maximum. Efficiency is a minimum of 85% at full load at 12Vdc output.
The 100W AC-DC power supply is built on a 3” x 5” PCB and is a custom version of our field-proven MIW 100-F0 power supply. The current limit is adjusted to precisely 100W output power.
Convection cooling and mechanical characteristics
Heat-sink fins on the side of the unit ensure up to +60ºC ambient temperature with pure convection cooling. A heavy-duty UTA 89 bracket on the rear side of the power supply provides secure attachment to a DIN rail. The unit measures 90 x 68 x 141 mm.
Safety standards, EMI and electronic protection
The MIW 100-U/12-F0PD-HF power supply meets Class II (IEC) protection requirements. A 90º faston connector is installed on the front panel for extra safety grounding. The input and output are filtered for low noise. The input meets EN55032 Class A with wide margins. The power supply is designed for compliance with EN62368-1 and equivalent safety standards. Electronic protection includes 4300Vdc input-output isolation, inrush current limiting, reverse polarity, over voltage, over temperature and short circuit conditions.
Conformal coating provides protection against humidity and airborne contaminants. Full electronic protection, low component count, large design headroom and the exclusive use of components with established reliability contribute to a high MTBF. The unit is manufactured at our plant under strict quality control.
