Fishing fleets from Iceland to Alaska have been using case isolated ground Eco-Tech 28V Alternators (IJ-28V/155-I) since the introduction in 2004. Standard 28V Eco-Tech Alternators (J-28V/155-I) are well suited for and have been used in construction and military vehicles. Eco-Tech 28V Alternators are being manufactured in J-180 and Pad mount versions.
Similar to Eco-Tech 14V Alternators, J-28V/155-I Alternators produce four fifths of their rated output of 155 Amps at idle. These Alternators have an efficiency rating of 80% at 2000 Alternator RPM resulting in increased fuel economy, longer life, and reduced waste heat.

- Eco-Tech Alternator produces about 4/5ths of its rated output at idle, that is 2 to 4 times the output of similar size Lundell alternators.
- Designed for vehicles that spend significant operating time at idle. Typical applications are fire, ambulance, shuttle bus, utility trucks,tow trucks and other high amps demanding vehicles.
- High efficiency of 80% @ 1800 Alternator RPM
- Eliminate 51%-52% fuel penalty caused by high idle
- Patented technology
- Voltage set point 28.2V 0.2V
- Permanent magnet and wound rotor design
- One wire hook up, self exciting
- Soft start
- Large brushes for longer life
- Heavy duty bearings
- Over voltage protection
- Load dump protection
- Three high efficiency internal fans
