Datasheet - DDP400HV Series

The operating voltage range is 277/347/480 with a full input range of 249 to 528 VAC. Available in 24, 36 and 48 VDC standard output variants, each model includes 12 VDC and 5 VDC auxiliary outputs. Housed in an IP67 sealed enclosure, the unit includes flying leads for both input and output.

An optional heatsink is available for additional heat dissipation, or the unit may be installed directly to the end equipment with heat transferred by conduction.
