HDU45, HDU60 & HDU100 series switching mode power supplies, 19-inch compatible Eurocard format, 12/24/48VDC input range, meet EMI CISPR PUB. 22 & FCC Class B safety standards, meet CE Marking standards
The HDU45, HDU60 and HDU100 series are 19" Eurocard compatible DC‑DC switching power supplies offering multiple input voltage ranges (9‑18 V, 18‑36 V, 36‑72 V) and output power levels from 45 W to 100 W. They meet EMI standards CISPR PUB 22 and FCC Class B, include CE marking, and provide built‑in over‑voltage and overload protection.
All models use a DIN 41612‑H15 female connector for both input and output, feature adjustable output voltage, remote sense (on HDU60/100), and are housed in a forward‑converter topology with free‑air convection cooling. Mechanical dimensions, weight, and connector pin assignments are detailed for each series.
