Isolating transformers
Application
Isolating transformers are used to (galvanically) isolate power supply units or sensitive appliances from the public electricity grid. This increases electrical safety and reduces the risk of electrical accidents. Isolating transformers also reduce disturbances from the grid, such as transients, current spikes, overvoltages and harmonics, which in turn contributes to significantly increasing the service life of connected devices.
Examples
When connecting computer equipment to ungrounded outlets.
Eliminates the risk of enclosures and metal parts becoming live if equipment malfunctions.
When working with hand tools on construction sites, for example.
When using sensitive measuring instruments.

Rectifiers
Application
Our rectifiers have a simple and robust design that provides good durability at a low price. There are filtered, unfiltered, stabilized and unstabilized versions.
1-phase rectifier
- Available with or without filter.
- Primary voltage 230 V, 50-60 Hz and secondary voltage 12 or 24 V.
- Standard sizes are 1.6 to 50 A. Other designs are made to order.
3-phase rectifier
- Primary voltage 400 V, 50-60 Hz and secondary voltage 24 V.
- Low hum voltage thanks to 6-pulse rectification.
- The 3DA models also have a static shield between the primary and secondary, which attenuates high-frequency interference.
Stabilized rectifiers
- Designed for industrial use and therefore very robust, both mechanically and electrically.
- Stepless adjustment of the output voltage.
