Modern test and measurement instruments place the highest demands on their power supply. Whether in medical technology, industrial automation, or particle physics – a stable, low-noise, and precise high-voltage supply is often the decisive factor for the success of an application.

As a specialist for high-voltage power supplies, High Voltage (HVPS) Condatas AG, based in Schlieren near Zurich, develops tailored solutions precisely engineered for these technological challenges. In this article, we present three examples from our high-precision custom module portfolio: the SP7281, the SP7289, and the powerful SP7293.

Please note: The modules presented here represent only a selection from our extensive portfolio. The standard lead time for new custom modules is approximately 12 weeks.

Selecting the right high-voltage power supply depends significantly on the specific application. We examine three modules that cover different performance ranges and fields of use.

The programmable SP7281 module (1W, 0 to -10kV) was designed for applications that demand the highest stability in the smallest possible footprint [1]. It is distinguished by an exceptionally low output ripple of less than 200mV P-P.

Applications: This module is predestined for medical technology, high-sensitivity analytics (such as mass spectrometers), and materials research – wherever low-noise, high-precision power supply is indispensable.

For more energy-intensive and industrially demanding processes, the SP7289 (10W, 0 to -15kV) delivers the optimal combination of high power output and excellent voltage accuracy (< 1.5%) [2].

Applications: This robust power supply is the ideal choice for industrial automation, semiconductor manufacturing, and electrostatic coating systems. It ensures a continuous and reliable power supply even under demanding operating conditions.

When extreme voltages are required with minimal output ripple (< 1% P-P), our most powerful module comes into play: the SP7293 (5W, 0 to +36kV) [3].

Applications: Designed for specialized research laboratories, particle physics, and X-ray generation – fields where maximum voltage capacity and absolute reliability are paramount.

To simplify your selection, we have consolidated the key technical data of all three modules into a single overview:

Model	Power	Output Voltage	Accuracy	Ripple	Switching Freq.
SP7281	1W	0 bis -10kVdc	+/- 1%	< 200mV P-P	180 kHz
SP7289	10W	0 bis -15kVdc	< 1.5%	< 0.1% (15V P-P)	170 kHz
SP7293	5W	0 bis +36kVdc	< 5%	< 1% P-P	60 kHz

Alle unsere Module verfügen über integrierte Schutzmechanismen (wie den kontinuierlichen Kurzschlussschutz) und sind auf maximale Betriebssicherheit ausgelegt.

Whether you need maximum precision for a mass spectrometer, robust performance for industrial applications, or extreme voltage for research – High Voltage (HVPS) Condatas AG provides the right solution.
