Rectifier Chargers GR(B)
Product Line: Rectifier Chargers (TECNED)
Manufacturer: Technology (for) Energy Conversion The Netherlands
Power: From 0.1kW to 15kW
The GR(B) series is the basic charger available in the TECNED GR product family with limited options. It strictly adheres to a truly industrial design with convection cooling and is built for 20 years operational life-time.
The TECNED GR (B) Rectifier / Charger series is available from 24Vdc to 650Vdc nominal with up to 100A output in a single enclosure.
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).
Like all GR-models, the GR(B)-series is short circuit proof, includes high DC protection as standard to protect the load and delivers a steady output voltage under al operating conditions.
Optional built-in batteries up to 9x 12V/100Ah for 110Vdc installations can provide back-up for small and medium installations. In combination with 12V/40AH and 12V/75AH batteries, up to 8 x 2P distributions MCB’s can be fitted for easy implementation.
The GR(B)-series is supplied in a floor standing sheet steel cabinet with bottom cable entry.
