High voltage DC-DC converters feature ultra-low noise for analytical instrumentation

XP Power delivers ultra-low noise power that is ideal for a wide range of noise-sensitive scientific applications. The new HRF15 are suitable for areas such as mass spectrometry, scanning electron microscopes, electron beam, capillary electrophoresis, x-rays and more.

Analytical instruments requiring ultimate precision are often sensitive to electrical supply noise and drift. The new device is a precision high-voltage DC-DC converter that can deliver voltages up to 15kV with exceptional load and line regulation, and low drift and ripple.

The single output voltages can be specified as 10kV, 12kV and 15kV as standard, with other voltages available upon request. Each unit can deliver 15W of power from a +24VDC input and the output rail is fully adjustable from 0-100%.

Intended for use where precise power is essential, the series offers output ripple values as low as 0.001% and stability of 10ppm/hr (25ppm/8 hrs) with a temperature coefficient of just 25ppm/C. Hence, the units provide consistent results, even when ambient temperature fluctuates.

Line and load regulation can achieve 10ppm, which delivers superior performance in load-dependent applications and situations where the supply voltage may fluctuate. The output current and voltage are regulated, and both are programmable from 0-100%, permitting a wide range of loads to be catered for.

Also, short circuit and overload protections are included in voltage and current monitoring and control.

Despite the flexibility and precision, units are housed in a small metal case measuring just 162mm x 72.4mm x 33mm (6.4” x 2.85” x 1.3”) and weighing 465g (1.03lb) approx. Input and controls are via a Dsub 15 connector mounted within the case.

Units are fully certified for UL61010 and UL62368 for safety and can work at ambient temperatures up to +50C.

The HRF15 delivers flexibility, advanced functionality, precise technical specifications and comprehensive safety approvals, enabling it to be integrated into a wide range of high-voltage applications in analytical instruments and semiconductor fabrication equipment. The units are available directly from the company and have a three-year warranty.
