Aplab manufactures high voltage dc lab supplies series which offers range of ten models regulated supplies for use in industries, research labs, capacitor testing, etc. All these high voltage dc lab supplies models have electrically floating outputs except 3000 v and 5000 v models and operate in constant voltage current limiting mode. The suffix n is used when negative output terminal is grounded and p is used when positive output terminal grounded. These dc lab supplies come with salient features like laboratory bench unit, digital output metering, constant voltage current limit type character, micro switch provided for protection against shock, 3u high [133 mm] and power saving thyristor pre-regulator technique.
