The TECNED GR(HS) series is a modular industrial rectifier and battery charger system designed to provide reliable and continuous DC power for critical applications. Engineered for utilities, infrastructure, data centres, and demanding industrial environments, it combines a compact modular architecture, natural cooling, and advanced system supervision to ensure high availability and low maintenance. Available for 24, 48, 110, 125, and 220 Vdc applications, the GR(HS) uses naturally cooled power modules without fans or moving parts, reducing mechanical wear and maintenance requirements.

Its hot-swappable power modules allow fast replacement and servicing without interrupting operation, while the N+1 redundant architecture ensures enhanced reliability and operational continuity. Supporting up to six power modules, the system provides efficiency up to 95%, high input power factor, automatic float and boost charging, and accurate load sharing. An integrated LCD display provides clear monitoring of operating values, alarms, parameters, and event logs, while programmable alarms, earth fault detection, and RS485/Modbus communication provide comprehensive system supervision. The GR(HS) is a dependable and low- maintenance DC power solution for mission-critical installations.
