The Emerson/Artesyn/Astec 73-551-0005 is a 210W switching power supply module from the MP series, engineered for industrial modular power applications requiring distributed DC output. This chassis-mounted unit delivers 20V DC at 1.0A with 380V AC input, featuring integrated power factor correction and EN61000-3-2 harmonic compliance. The module incorporates current sharing on outputs rated 10A or greater, remote sense capability on outputs exceeding 2A, and overload protection across all outputs. Voltage adjustment and margining functions are available on single output modules. An Input-OK signal with status indicator LED, DC OK signal, and isolated 5V bias voltage support system-level control and monitoring. Global and individual inhibit/enable control enables flexible power sequencing within multi-module configurations.
