High Voltage Solutions

MCR Series

Miniature Regulated High Voltage Converters

Miniature regulated 24 VDC-input high voltage converters for low-current instrumentation. A 0-10 V program input provides proportional output control, while a floating output supports fixed positive or negative polarity. PCB-mount and connectorized configurations accommodate multiple integration environments.
