Johnson Controls A525AEDN-0203C Electronic Defrost Temperature Control

The Johnson Controls A525AEDN-0203C Electronic Defrost Temperature Control is another subassembly play an Essential role in defrost for refrigeration systems, to avoid the ice formation. This is a panel-mount controller made of high impact plastic for durability and has a temperature range of -40°F to 160°F. It employs two SPDT relay contacts to control defrost heaters, compressors and evaporator fans during the defrost period. The A525AEDN-0203C operates on a standard voltage of 24VAC and has an output current of 4 ~ 20mA compatible with building automation systems. This controller optimizes the performance of the system, especially the energy economy efficiency through appropriate management of defrost temperatures.
