Magnetic-free high voltage modules suit portable designs

EMCO High Voltage Corporation’s P Series is a line of micro-power high voltage power supplies designed to meet the demands of mobile, battery-powered detector applications, including portable radiation detection devices.

The P Series offers fully regulated and programmable outputs of 0 to 1,200V or 0 to 2,000V in a lightweight, miniature PC-mount package. Consuming less than 4mA at full output and housed in a case less than a quarter-inch tall, the P Series is well suited for battery-powered applications.

A unique inductor/transformer-less design, low-noise circuitry and shielded case make the P Series suitable for very sensitive detector applications. Ripple is less than 100 microvolts peak to peak. The soft-start feature is specifically designed to protect sensitive detectors used in portable radiation and explosives detection equipment.

A precision on-board voltage reference is provided for full-scale, fixed or variable output configurations, which facilitates plug-and-play designs. The P Series provides on-board voltage monitoring as a proportional 1,000 to 1 voltage and accommodates a wide input voltage range of 5 to 12V. Models are available in positive and negative outputs.
