ONV (19inch)

Industrial grade 19inch based UPS

TECNED Industrial grade UPS are based on transformer technology for robustness and endurance. The input and output isolation transformers protect the semiconductors against spikes, surges, peak currents and distortion, supply short circuit currents and filtering noise. Transformer based technologies offer therefore a longer service life and higher degree of protection.

Based on this topology, TECNED provides a highly reliable charger / inverter product combination designed for demanding operating environments.

The ONV(19inch) series strictly adheres to a truly industrial design and is built for 20 years operational life-time.
