EPMG-1270 EPMG-2470 Generator Excitation Boost System. A Cost-effective excitation solution better than PMG

EPMG-1270 / EPMG-2470

Excitation Boost System

EPMG® converts DC battery power into a separate excitation source to provide “boost” for self-excited (shunt) generators during heavy transient loads – providing PMG performance for much less cost. Available in 12V (EPMG-1270) and 24V (EPMG-2470).

Features

  • EPMG® installs quickly and easily in series with any AVR (excitation current below 8A) in a self-excited generator
  • EPMG® converts genset battery and/or other battery power into a separate excitation power source for dynamic response for heavy load used such as motor starting and short circuit situations – operating only when required
  • Upgrades self-excited generators to PMG type performance
  • Battery voltage abnormal / reverse polarity / current limiting protections
  • Power output self-test
  • Built-in DC fuse protection
  • Low power consumption when not in use (hibernate mode)
