THYROTRONIC
Robust and reliable, tried and tested
Battery-supported DC power supply systems have proven to be extraordinarily reliable and very economical back-up power supplies for many decades. The reliability of a battery-supported backup power supply depends on the quality of the battery used and the operational reliability of the rectifier device.
BENNING has developed the THYROTRONIC rectifier series to be particularly suitable for use with battery-supported DC power supplies. In addition to great reliability, it offers a comprehensive signalling and monitoring concept.
- Constructed from few but reliable components
- Mechanically and electronically resistant, designed for harsh environmental conditions
- Wiring concept
- State-of-the-art DSP technology
- Automatic temperature-controlled charging characteristic
- Galvanic isolation
- High quality output power
- Fully controlled thyristor three-phase bridge, 6 pulse (standard), 12 pulse (optional)
THYROTRONIC rectifier devices work with an electronically controlled output characteristic (IU characteristic according to DIN 41773) and are suitable for use with lead and NiCd batteries as well as other modern battery technologies.

- various signaling and monitoring modules
- Suitable for all battery technologies
- Programmable automatic boost charge
- Equalising and initial charge
- Parallel operation of several rectifiers with active or passive load sharing
- Automatic and programmable battery circuit test
- Automatic battery capacity test
- Compensation of line resistance
- Display of the remaining battery life
Signalling and monitoring modules

Modern touch display with intuitive guidance through a user interface optimized by BENNING
All available measurement channels can be provided with measurement and error thresholds. Freely definable limit values can be set to trigger the error or warning messages. The display and control unit built into the front door of the rectifier housing is used to enter the limit values and to confirm and visualise the messages. Optionally, the system can be equipped with a 10” touch display, which sets completely new standards in terms of ease of use and comprehensibility.
Supported monitoring types:
- Network monitoring
- Battery and DC voltage monitoring
- Temperature monitoring
- Over- and undervoltage monitoring
