RID-85B

The Mean Well RID-85B is an 88-watt enclosed AC/DC converter designed for industrial and commercial applications requiring stable dual-voltage power distribution.

This unit delivers a primary 5V output at up to 8A alongside a secondary 24V output rated at 2A, meeting a total rated power of 88W. The design incorporates a wide universal input range accepting 88 to 264VAC or 125 to 373VDC across a frequency span of 47 to 63Hz.

Engineered for robust performance, the RID-85B achieves typical efficiency ratings of 80 to 81 percent while maintaining low ripple and noise levels of 80mVp-p on the 5V channel and 120mVp-p on the 24V channel. Comprehensive protection features include overload protection spanning 110 to 150 percent of rated output, overvoltage protection clamping at 5.5V, and hold-up times of 18ms at 115VAC and 100ms at 230VAC.

Mechanically, the converter measures 159mm by 97mm by 38mm, facilitating straightforward integration into control panels or equipment racks. It operates within a temperature range of -25°C to +70°C and meets stringent safety standards including UL60950-1 and TUV EN60950-1. With a calculated minimum MTBF of 239,400 hours at 25°C, this power supply provides reliable continuous operation for demanding electronic systems.
