AVR SERIES
Output Voltages 100Vdc up to 1000Vdc at 1 Watt
Miniature, Isolated, and Regulated
The Series AVR High Voltage DCDC Converters is intended for users needing a miniature, isolated, regulated
voltage source. These 1 Watt single output units offer high regulation along with low ripple and stability. AVR
Units are protected against input Overvoltage, Output Overcurrent and Over Temperature. With no minimum load
required, units can be safely operated from No Load to Full Load. Encapsulated in a miniature case and potted,
units will operate over a temperature range of 25ºC to +70ºC with no heatsink or power derating.
These units are suitable for applications like electron beam deflection or focussing, photomultiplier tubes, piezo
transducers or any other applications requiring regulated, isolated highvoltage sources.
