The First ISO Micro Compliant Solid State Relay up to 30A
The ESR10 Micro Electronic Standard Relay is a solid-state relay designed to replace standard electromechanical relays. The device complies with ISO Micro standard automotive relay sockets.
The ESR10 Micro is a high side switching, normally open (NO) relay which can be controlled bipolar with a positive signal and takes up to 10 A respectively 30 A permanent current.
- The low power consumption compared to standard electromechanical relays allows fuel saving and reduction of CO2 emission by very low hold current.
- The solid state power device is virtually wear-free with any kind of load
Applications:
The ESR10 is suited for applications, where magnetic valves, motors or lamp loads must be switched and protected.
- Road vehicles (cars, bikes, trucks, buses, work and utility vehicles, special vehicles)
- Construction and agricultural machinery
- Rail vehicles
The ESR10 is also suitable for industrial use (process control, machine-building) as well as the marine industry (work boats, sport, motor and sailing ships/yachts).

- Integral power electronics provide a non-contact switching function, tolerant to shock, vibration and dust.
- Silent switching
- Only a fraction of the switching and hold current is needed compared to electro-mechanical relays. This is important for battery buffered load circuits which have to remain controlled even with the generator off line and helps reduce CO2 emissions.
- Fits to standard ISO micro automotive socket
- 24 VDC 10 A version coming soon.
