The WT-2 Voltage Regulator is an encapsulated unit contained in a plastic case. The regulator controls the dc exciter field power of conventional, 50 or 60 Hzbrushless generators that have a max 63 Vdc exciter field to regulate the generator output voltage. Regulation is provided by sensing the generator  output voltage, converting it to a dc signal and comparing the signal to a reference voltage signal. An error signal is developed and used to control  the dc field power in order to maintain a constant generator output.
