Low Voltage ≤ 1,000 V DC

Power supplies for voltages up to >1,000 Volt at high precision. Laboratory and industrial power supplies for different applications.

The units are available in many output ranges and for very high currents up to 10,000 A.

Select the power supply technology suitable for your application. Heinzinger low-voltage power supplier are available as linear-control or switch-mode power supplies and can meet even unusual or complex technical requirements.

Extensive interface solutions are available for the integration into external controls.

Thanks to comprehensive options, our standard units can be tailored to your application without problems.

We developed separate product lines for special applications, such as magnet power supplies or power supplies for electromobility and automotive applications.
