High Voltage Power Supplies

Our high voltage DC power supplies meet a wide range of high performance demands

For over four decades EMCO High Voltage Corporation, now a part of XP Power, has led the industry in designing and manufacturing high voltage power supplies for original equipment manufacturers, research laboratories and educational institutions worldwide. Our mission is to provide you with performance driven, space saving, cost effective and highly reliable high voltage solutions backed by on-time, zero defect production support. 

XP EMCO has been continuously advancing high voltage technology by introducing new products offering superior performance in smaller packages at comparable or lower prices. In fact, many of today's industry standard footprints for high voltage modules are XP EMCO originated designs.

Our uncompromising commitment to quality and reliability throughout the last four decades has resulted in our products becoming a trusted part in many generations of our customers' products. Whether operating in outer space, deep underground or in sensitive laboratory equipment, our products are depended upon for their high performance and reliability.

Our extensive high voltage design and manufacturing experience enables us to develop and manufacture new products using proven high reliability components and processes. All XP EMCO products are designed and manufactured in XP EMCO’s "Flex-Chain" lean, demand-flow process that provides maximum quality, short lead-times, and assures our customers the lowest total cost of ownership.

High Voltage Power Supply Products

Our high voltage DC power supply products meet a wide range of high performance demands. From precision analytic instruments to mission-critical equipment, our customers’ applications all have one thing in common: the need to deliver consistent performance without fail. For over 40 years, XP EMCO High Voltage has been meeting and exceeding the requirements of our customers. Whether you are developing sensitive laboratory instruments or scientific equipment that must perform under the most rugged conditions, you can depend on our products to fulfill your need for high performance and reliability.


Provides versatile low cost DC to high voltage DC conversion with proven reliability. The output voltage is directly proportional to the input voltage and is linear from 0.7V to the maximum input. Options include an output centre tap to provide both positive and negative outputs from one low cost module.


Precision regulated DC - HVDC modules that feature easy external control and design-in. Providing a stable HVDC output over the specified input voltage and load range. Fully programmable from 0 - 100% of the nominal output voltage via a linear low voltage control input.


Let XP EMCO design a custom or semi-custom power supply that meets your project's individual specifications. We have experience designing high voltage products for a broad spectrum of applications, from satellite communications systems to precision scientific instruments. AC inputs are also available.
