Lamps indicate the presence of input voltages and which voltage is applied to the primary windings. The regulator is rated at 2,500 W, and output voltages in either mode are held within ±3% over an input voltage range of 9% to 20%. Inputs include a wideband filter-suppressor to reduce disturbances from power lines and other connected devices.
