Sprint Electric 340i Product Manual

Model 340i / 680i / 1220i DC drive product manual HG102938 iss 8
This drive is an isolated 1 Quadrant speed controller for shunt wound or permanent magnet motors. It utilises
speed feedback from the armature voltage (Avf), or from a shaft mounted tachogenerator. It incorporates a
fully controlled thyristor bridge with a current loop to protect the drive and motor. It can be used in speed or
current control modes.The drive can motor forward and will regenerate for reverse rotation by an external
force. Please obtain expert help if you are not qualified to install this equipment. Make safety a priority. This
component is hazardous.
POWER RATING
