Eco-Tech 28V/200A Isolated Ground Ignition Protected Alternator

Applications where recharging intervals are short require a higher ampere output in order to recharge batteries quickly. The Eco-Tech 200A alternator in both J-180 and pad mount configurations (IJ-28V/200-IP and IP-28V/200-IP) were developed to satisfy such high demand needs. These models are also available in isolated ground and ignition protected models.

The 200A alternators have both high efficiency (80% at 1,800 RPM) and uniquely high output at low RPM’s (idle). Therefore using Eco-Tech 200A alternators results in increased fuel economy, longer battery life, and reduced waste heat.

Features & Benefits

  • Eco-Tech 200 Amp 28V alternators generate 145A (80% of rated full output) at 1,800 alternator RPM’s, which is engine idle. Idle output is about 2 and 1/2 times the output of similar size claw pole (Lundell) alternators.
  • Designed for vehicles that spend significant operating time at idle. Our isolated ground, ignition protected alternators were specifically designed for military application.
  • High efficiency of 80% @ 1800 Alternator RPM
  • Eliminate the 50% fuel usage increase caused by high idle
  • Patented technology
  • Voltage set point 28.3V
  • Permanent magnet and wound rotor design
  • One wire hook up, self exciting
  • Soft start
  • Large brushes for longer life
  • Heavy duty bearings
  • Three high efficiency internal fans
  • Internal regulator
