In the area of relays SPS electronic GmbH offers high voltage relays RL 42 and RL 21.

SPS electronic is one of the most successful developers and manufacturers of test systems for electrical safety testing. The core competences are to be found in below products: safety test devices, test systems for integration into the automation and surge testers. In the field of high voltage (HV) SPS electronic manufactures in Germany for example the high voltage test device HA 3881B, HA 5012L or HA 3600A.

High voltage test devices serve to test clearances and creepage distances. The rating of test voltages is specified in standards: IEC standard, EN standard, UL standard, VDE standard

It applies the rule of thumb: rated voltage x 2 + 1000 V

The SPS high voltage test devices of series HA 5012L are intended for use in automatic test systems alone.

Via a potential free 24 VDC interface the devices are remote controlled. Current and voltage are transmitted via analogue, potential free signals (0 - 10 VDC). Aanalogue inputs (0 - 10 VDC) are available for the setpoints.
