Higher voltage for high precision DC-DC converter for medical and analytical equipment

New Products |
By Nick Flaherty

Advanced Energy Industries has expanded its high voltage, high precision DC-DC converter range with three new models with higher maximum output voltage.

The UltraVolt 20LE, 25LE and 30LE chassis mounted DC-DC converter units range from 20 to 30 kV DC maximum output voltage. They join the LE Series’ existing line of six DC-DC converter models that range from 1 to 15 kV DC maximum output voltage. The UltraVolt LE Series has low ripple and stable performance over temperature for a variety of precision high voltage applications.

“With the expansion of our LE Series, customers now have a broader range of regulated DC-to-DC converters from which to choose, in particular for applications that require higher voltage,” said Conor Duffy, vice president and general manager of high voltage and low voltage at Advanced Energy. “High precision medical and analytical equipment are core markets for our LE Series, where consistent high voltage performance in varying ambient temperatures and line loading conditions are critical for ensuring the most robust performance especially in mass spectrometry, electron and ion beam steering and focusing optics, capillary electrophoresis and electrostatics applications.”

Other benefits of the LE DC-DC converter Series include better measurement repeatability, resolution and longer-term reliability; enhanced high voltage output performance by minimizing control signal noise and drift; and acceleration of both electrical and mechanical integration tasks. 

The units have a single output with positive and negative polarity models and 4, 15 or 30 W of maximum output power at 0 to 10V from a 24Vdc input and a temperature coefficient of 25 ppm/°C. There is also an enhanced output stability option for operation down to 0 VDC on the 4W unit.

Product details and technical specifications for the full LE Series are available on the UltraVolt LE Series webpage.
