9.3 Power Components
Armature Bridge
All armature bridge devices are dual SCR isolated power modules rated at 1400 volts (minimum)
repetitive peak off state and reverse voltage and have 1000V/uS dvdt. There are 3 each on EPN
Series models, PMD3-5, and 3 additional, PMD6-8, on EPR Series models. Current ratings are
per control model.
NOTE:
The IR (Internaltional Rectifier) modules are not pin-for-pin compatible with the Eupec
and Semikron modules. The gate and cathode signal leads on IR modules are reversed on the
second SCR device. Consult factory for assistance when replacing a Eupec or Semikron module
with an IR module or vice-versa.
