Field Replacement
The PDI-772HE is a specialized, high-efficiency power supply that
incorporates very high bandwidth RF circuitry. Unique to the design, a
diplexed RF circuit that provides RF CATV signal and 28 VAC power to
10 discrete outputs rather than the 8 binary style outputs found
commonly in passive RF distribution networks.

not recommended. The power supply must be removed and returned to
the manufacturer for servicing.
