Battery-backed DC-power supply systems are securing the supply power to monitoring and regulation devices for oil & gas installations, industrial processes, public transportation and power grid. DC back-up units are widely used in nearly all fields of industry and public life and play a vital role in areas of safety, power management and power availability.

The TECNED GR (SF/D) Rectifier / Charger series is available from 24Vdc to 650Vdc nominal with up to 600A output in a single enclosure. The GR (SF/D) series can be configured to charge common battery types from VRLA to NICAD and to include boost-charge and equalize options.

TECNED rectifier/chargers are based on Thyristor + Concept (SCR+IGBT) technology with a galvanic separation transformer, input PF 0.98, low input harmonics (<10%), standard low DC ripple (< 2% for 3-phase systems).

The GR (SF/D) series can be supplied as standard or fault tolerant systems within a single enclosure to meet customer requirements for safety and reliability.

The GR-SF (software free) model is a strictly analog charger available with natural convection and forced air cooling depending on requirement. Standard features include battery- A / load-V metering, mains failure / DC-high/low and general alarm with potential free contacts and input/output plus battery fuse monitoring.

The GR-D model includes an additional digital controller with LCD display that shows the systems current state of operation and system values, allows setting of system parameters and includes event and alarm logs.
