Dell 071-000-438 HM202 400W 12V D ACBEL EMC Power Supply

071-000-438 is a 400W power supply compatible with DAE2P/DAE3P. The units integrate independent power supply and dual-blower cooling assemblies into a single module. The enclosure cooling system includes two dual-blower modules. If one blower fails, the others will speed up to compensate. If two blowers in a system (both in one power/cooling module, or one in each module) fail, the DAE2P/DAE3P will go off line within two minutes.
