**HVR high voltage relay - hybrid and powerful**
## **Description** ee
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.

## **Features**
- l Continuous current capacity of 300 A at 25 °C or 250 A at 85 °C.
- l The 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.

## **Instructions for use of the drive**
The HVR10 has an energy-efficient bistable drive. Therefore, it only consumes typcially 0.2 W (12 V * 18 mA). Only when changing the operating conditon from ON to OFF and from OFF to ON will a current be required of max. 14 A for a very short time (30 ms). The HVR10 draws this current from the operating voltage supply and not from the controlgear.
In order to realise this energy-saving feature, it has to be tolerated that the HVR10 cannot change its switching status automatically as soon as the supply voltage is off. If your safety concept is based on an automatic opening of the high voltage relay in the event of an accident, we recommend to use a conventional monostable high voltage relay in the minus path.
This will make the entire system significantly more robust because the HVR10 switches the power in the plus path and the cheaper mechanical relay only follows in the minus path.
- 1 The HVR10 behaves like a monostable relay as long as the supply voltage is ensured.
- 2 Arc suppression intervenes from a voltage of approx. 25 V.
- 3 See safety-relevant functions - make operation on a present short circuit.
- 4 When new.
- 5 Cannot be maintained when contact closed at no load. Min. current 1 A

## **Typical switch-on operation**
1. Apply operating voltage to PIN 1 and PIN 3. This voltage supply must continuously be ensured. The energy for the drive will be drawn from this power supply and not from the controlgear.
2. The status output indicates OK by drawing the HIGH level from the controlgear to the ground on PIN 4 (state).
3. As soon as a HIGH level is applied to PIN 2 (> 9 V), the HVR10 switches on the load circuit.
4. The status output continues to indicate OK by drawing the HIGH level from the controlgear to the ground on PIN 4 (state).
## **Typical switch-off operation**
1. As soon as a LOW level is applied to PIN 2 (< 5V), the HVR10 switches the load circuit off.
2. The status output continues to indicate OK by drawing the HIGH level from the controlgear to the ground on PIN 4 (state).
3. The operating voltage can be switched off after > 100 ms, e.g. when the vehicle is parked.
## **Safety-relevant functions**
- l **Make operation onto an existing short circuit** We expect that the HVR10 is operated in a pre-charge jig. Therefore, it is probable that there is a defect when the current rises to 1000 A within 1 ms when switching on. The HVR10 monitors the current rise during switch-on operation. If a short circuit is suspected, the mechanical contact system will not close in the first place. The semi-conductor bypass will open the load circuit and the controlgear is informed about the fault via the feedback signal. The device is reset when the control signal is set to »low« and back to »high« again.
- l **Monitoring of switching status:** By means of a light barrier, the position of the mechanical main contact is continuously monitored. If the desired posiiton of the mechanical main contact cannot be established, the HVR10 will signal this critical operating condition.
- l The housing is also available in the high voltage warning colour (orange, RAL 2003).
- l The HVR10 was designed and manufactured to IATF 16949 and thus meets the ASIL-Level-QM. It was designed as a standard catalogue product. Due to special safety requirements from customer side, we are inable to indicate a higher level.
- l The HVR10 itself does not have a fail-safe element.
- l The HVR10 does not require any maintenance work.
**==> picture [174 x 106] intentionally omitted <==**
- l Internal monitoring detects and signals the following conditions/ errors:
- Switch-on command cannot be carried out
- Switch-off command cannot be carried out
- Operating voltage too low, lower than 10 V
- Internal fault of microcontroller
- Cable to controlgear interrupted
- Cable to power supply interrupted
- Unreliable frequent switching operation within a short time (temperature management)

- l Touching live parts can cause serious injuries (the device has unprotected live parts, 1,000 V).
- l Caution: The switching operation may cause voltage peaks up to 2,500 V.
- l After disconnection of overcurrents, the device may be no longer usable. Please check in advance or replace.
**==> picture [32 x 31] intentionally omitted <==**
- l During switching operations, the device may cause electrical and/ or magnetic interferences.
- l Aggressive media can damage the device externally. Damages devices must be replaced.
- l For proper operation, the device must be mounted/closed by means of four M5 screws.
- l Do not mount side-by-side, in particular not with other heat sources. Heat accumulation must be avoided.
- l Before switching high voltage, please switch the device repeatedly without activated main circuit to test proper wiring of the control side (observe max. peak currents).
- l The device is maintenance-free over the entire life span. Endurance depends on the application.
- l Do not drop.
- l Damaged devices must be replaced immediately. E-T-A does not accept any warranty for damaged devices that are put into operation.
- l Please do not further use in the event of malfunction.
