The DG040-7 is a 40W open frame AC-DC converter manufactured by Tri-Mag, LLC. It accepts a universal input voltage range of 90 VAC to 264 VAC with a frequency range of 47 Hz to 63 Hz. The converter features built-in active Power Factor Correction (PFC) and delivers a typical efficiency of ≥86% at rated load.
Electrical specifications include a line regulation of ±0.5% typical, load regulation of ±1.0% typical, and ripple and noise less than 1% pk-pk typical. The device provides overvoltage protection (latch off), overload and short circuit protection (auto recovery). It can deliver 40W continuous power with a peak power capability of 55W.
The converter is housed in an open frame package with a chassis mount form factor. Dimensions are 76.2mm (3.00") in length, 50.8mm (2.00") in width, and 23.1mm (0.91") in height. Cooling is achieved via free air convection. The operating temperature range is -20°C to 70°C with derating above 50°C.
Isolation ratings are 4000 VAC input to output (2x MOPP), 1500 VAC input to ground (1x MOPP), and 1500 VDC output to ground (1x MOPP). MTBF is greater than 500 kHrs per MIL-HDBK-217F at 50°C. The switching frequency is 120 kHz typical.
