E-T-A MPR20 Mechanical Power Relay

The Most Energy-Efficient Monostable Power Relay

The MPR20 is a monostable electro-mechanical high current relay. Its wide range input allows installation and operation in both 12V and 24V on-board electrical systems without change of the hardware and it carries 300A continuously. In the event of a power disruption, the relay will at once go into its original state due to its monostable design.

Reduction of holding power by 80% and of pull-in power by 50% allows direct connection to the controlgear and provides additional cost reduction and environmental advantages in spite of a monostable design. By using standard termination technologies and mounting dimensions, the MPR20 can easily and quickly replace conventional relays.

Benefits:
• Reduced fuel consumption and CO2 emission due to an 90% lower holding power
• Flexible installation for demanding applications due to a robust, water- and dust-proof design
• Reduced installation time through direct connection to the controlgear

Technical Data:
• Voltage Ratings                      DC 12V/DC 24V
• Current Ratings                     100A/200A/300A
• Degree of Protection            IP6k9k (IP67)
• Ambient Temperature          -40°C … +85°C
• Pull-In Current                       DC 12V: 2.5A/DC 24V: 3A
• Holding Current                    DC 12V: 0.12A/DC 24V: 0.7A

Standards:
• ISO 16750
• IATF 16949
• ECE R118
• ECE R10
• ASIL upon request

Typical Applications:
• Buses, trucks, construction machinery, agricultural vehicles and forestry equipment as well as special vehicles
• Air-conditioning, compressor units, battery isolation switches and applications in accordance with Machinery Directives

E-T-A HVR10 High Voltage Power Relay – Hybrid and Powerful

The Most Powerful High Voltage Relay Up To 1000 V

 

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:
• Continuous current capacity of 300 A at 25 °C or 250 A at 85 °C.
• 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.
• 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.
• For a short period of time, the HVR10 can carry up to 5000 A (25ms) and facilitates the co-ordination with a suitable HV fuse.
• 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.
• The hybrid switching concept uses an electronic bypass that successfully suppresses the arc, thus significantly reducing the thermal load of the mechanical contact system.

Benefits:
• Reliable disconnection even in critical conditions up to 2,000 A at 1,000 V
• High protection of the on-board electrical system through integral fault detection and indication
• Long life span through low-arc switching operation

Applications:
• All utility vehicles, e.g. buses, trucks, construction machinery, specialty vehicles with electrical power train, mining vehicles etc.
• Voltages beyond the 450 V system voltage, charging stations, power storage and main relays in the vehicle

Standards:
• ISO 16750
• IATF 16949
• ECE R10
