Intelligent power distribution, power relays and circuit breakers for protecting, switching and monitoring

In construction & forestry equipment, weather and other environmental influences such as dust, vibration and humidity play a huge role in the reliability of the equipment. Any components in these types of equipment must be able to withstand these harsh conditions, whether the machinery is used by private customers, service providers or rented. 

Preventative maintenance

In the field, unforeseen failures are always connected with high costs and risks. Comprehensive diagnostic data and a historical log allow early failure detection and the ability to do preventative maintenance and prevent standstills.

E-T-A’s CAN-capable products, particularly intelligent power distribution systems with current and voltage diagnosis, provide data back to the controller for preventive measures.

The evolution of smart technology

E-T-A products are on pace with the adoption of smart technology into construction and forestry equipment. Our products continue to move toward digitization with CAN bus capable components that communicate equipment status back to the controller. 

Increase equipment efficiency

The increase in electrical loads in construction and forestry equipment requires more installation space and power.

E-T-A's compact relays and power distribution systems allow for space savings and reduced wiring.  Circuit breakers and power distribution systems with integral load protection can easily be reset. This saves time and money spent trouble-shooting an issue.

Increase Equipment Reliability with Compact & Robust IP6K9K/IP67 Power Relays

E-T-A power relays are ideal for switching high current loads up to 300 amps as well as battery management in Construction & Forestry Equipment. The power relays are made with high-end and corrosion-proof materials, making them extremely robust and able to withstand environmental factors like shock, vibration, water and dust. The compact design and low weight enables flexible installation in demanding applications.

And, as a designer you are facing continuous pressures to design more competitive construction & forestry equipment all while reducing cost. Installing E-T-A’s power relays into your 12/24 VDC electrical system can help you:

  • Extend vehicle lifespan - > 250,000 cycles and corrosion proof materials helps increase the lifespan and reliability your equipment.
  • Enhance design flexibility - Standard and alternative mounting possibilities & IP6K9K/IP67 rating allow you to install the relay where it works best in your design - even in the harshest environments.
  • Save space & reduce vehicle weight - the MPR20 is more compact and weighs 50% less the standard relays on the market today.
