GR (B)

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.
