ER-340/-680/-1200

ER-340/-680/-1200 Variable Speed Drives

  • Armature Current: 3.4Amp – 12.2Amp
  • Range of 1 and 4 quadrant DC Drives
  • Power rating 0.55kW-1.9kW @180V dc
  • Compact design
  • Can be used in speed or current control modes
  • Compact design
  • CE, UL, and cUL approved

The ER-340, ER-680 and ER-1220 series are series of speed controllers for shunt wound or permanent magnet motors, utilising speed feedback from the armature voltage, or from a shaft mounted tachogenerator.

Description

ER-340/ER-680/ER-1220

  • Non-isolated component units
  • Incorporates an accurate current control loop to protect the drive and motor

ER-340i/ER-680i/ER-1220i

  • Isolated 1 quadrant speed controllers for shunt wound or permanent magnet motors
  • Incorporate a fully controlled thyristor bridge with a current loop to protect the drive and motor
  • Used in speed or current control modes
  • The drives can motor forward and will regenerate for reverse rotation by an external force

ER-340XRi/ER-680XRi/ER-1220XRi

  • Isolated 4 quadrant speed controllers for shunt wound or permanent magnet motors
  • Incorporate an accurate current control loop to protect the drive and motor
  • Used in speed or current control modes
  • Operate in forward or reverse, motoring or regenerative braking
