MITSUBISHI Regulators: Description
Regulator consists of two elements: constant-voltage relay and pilot lamp relay. Both relays consist of an electromagnet, contacts, frame, moving element and coil side plate. This regulator has a temperature compensation gradient as an improvement over the constant voltage charging system. It has functions for automatically compensating the adjusted value of the constant-voltage relay so that the adjusted value will be lower in summer and higher in winter.
