Rectifier Chargers GR(B) 19 inch
Rectifier Chargers GR(B) 19 inch (TECNED)
From 0.1kW to 50kW
The GR (19 inch) series is an advanced rack-based charger in the TECNED GR product family available with central monitoring and control options. It strictly adheres to a truly industrial design and is built for 20 years operational life-time.
TECNED Industrial grade rectifier/chargers are based on transformer technology for robustness and endurance. The input isolation transformer protects the semiconductors against spikes, surges and filters noise. Transformer based rectifier/charger technology combined with blocking diodes in the output offer a longer service life and higher degree of protection of your critical load.
Based on this topology, TECNED provides a highly reliable charger / inverter product combination designed for demanding operating environments.
The availability can be further increased with 2 or more rectifier/charger modules in parallel operation mode. Like all GR-models, the GR(19inch) series is short circuit proof, includes current limit, high voltage protection and potential free contacts.

Rectifier Chargers GR (B)(TECNED)
From 0.1kW to 15kW
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.
