LE Series - High Precision High Voltage Power Supply

The LE series of regulated DC-to-DC converters deliver up to 30 W of low noise, highly controllable, stable power. The series includes nine models that range from 1000 to 30,000 VDC. The models are available in single output positive or negative polarities and use 24 VDC inputs. Electrical and mechanical integration options can be factory-configured to meet your specific application needs.
