HVR high voltage relay - hybrid and powerful Description The HVR10 is a hybrid powerful high end high voltage relay in a compact design. It combines physical isolation of high voltages via an electro-mechanical contact and state-of-the-art semi-conductor technology. The hybrid, arc-free switching system allows 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 fist-sized unit can switch and permanently process 300 A at 900 V up to 50,000 times, arc-free and wear-free. The innovative self-monitoring function immediately signals critical operating conditions to the controlgear. HVR10 disconnection even in critical conditions up to 2,000 A at 1,000 V l igh protection of the on-board electrical system through integral H fault detection and indication l Long life span through low-arc switching operation utility vehicles, e.g. buses, trucks, construction machinery, specialty vehicles, mining vehicles etc. l Test benches Approvals Approval authority Rated voltage current capacity of 300 A at 25 °C or 250 A at 85 °C. rupture capacity of up to 2000 A at 1000 V is valid for both current directions without restrictions. It is therefore possible to lead even high charging currents over the relay. l Very low current consumption in the ON condition of typically 0.2 W (12 V * 18 mA) due to a bistable drive, which only draws power from the supply when the switching status changes. l For a short period of time, the HVR10 can carry up to 5000 A (25 ms) and facilitates the co-ordination with a suitable HV fuse. l The switching status of the mechanical contact system as well as the current rise upon switch-on operation is continuously monitored. This allows information of the control unit about critical operating conditions. l The hybrid switching concept uses an electronic bypass that successfully suppresses the arc, thus significantly reducing the thermal load of the mechanical contact system. l The Applications The HVR10 was mainly designed as a main relay for utility vehicles with electrical power train, also for voltages beyond the 450 V system voltage. It is especially suitable for vehicles where reliability and availability are at a premium.

HVR high voltage relay - hybrid and powerful Safety Indication l T he HVR10 has an energy-efficient bistable drive system. This drive system does not open automatically when the supply voltage is interrupted. Please observe during installation that the main contact could be closed. Please test the relay function before connecting the high voltage load circuit. I nstallation and start-up only be qualified personnel. P lease observe the following five safety rules: - switch off - secure against reset - check absence of voltage - ground and short-out - over or shield adjacent live parts c R...
