TECNED GR(HS) series
Industrial Rectifier Charger 24Vdc – 48Vdc – 110Vdc – 220Vdc – Modular design
The TECNED GR(HS) series is a module based, natural cooled rectifier/charger series offering an integrated system designed to meet modern requirements for utility companies, data centres, infrastructure and industry.
With natural cooling and hot swap features, the GR(HS) is low maintenance, giving a significant reduction in maintenance resources needed for optimum performance.
Natural cooling modules have no moving parts with structural wear, eliminating system disruptions due to fan failure and the need for periodic replacement of fans.
Designed with plug-in functionality and back-bone connectors, hot-swap allows modules to be replaced without shutdown or interruption to your process.
