High Voltage Relays
The E-T-A HVR10 high voltage relay is the right solution for the electrified power train in buses, trucks, construction machinery and specialty vehicles. The powerful unit is equally suitable for charging stations, energy storage and as main relay in vehicles.
The HVR10 is a hybrid powerful high voltage relay in a compact design. It combines physical isolation of an electro-mechanical contact and state-of-the-art semi-conductor technology. The hybrid, arc-free switching system allows repeated and reliable disconnection, even in the event of an overload, of up to 2 megawatts – 2,000 A/1,000 V. The HVR10 withstands high short circuit currents up to 5,000 A until the fast HV-fuse trips.
The compact unit can switch and permanently process 300 A up to 50,000 times, arc-free and wear-free. The innovative self-monitoring function immediately signals critical operating conditions to the controlgear
