Variable Speed DC Drives ER-3200i / ER-3600XRi

Variable Speed DC Drive

• Armature Current: 4Amp – 48Amp
• 1 quadrant power ratings
• 2.2kW-11kW @320V dc
• 4 quadrant power ratings
• 1.1kW-9.5kW @320V dc
• Can be used in speed or current control modes
• CE, CSA, UL and cUL approved

The units employ closed loop control of both armature and feedback voltage to give precise control of the motor torque and speed.

3200i/3600XRi

Thermally protected: The motor and drive are thermally protected by a stall timer which automatically removes power after 30 seconds if the required speed cannot be achieved.

High short term torques up to 30 secs: The drives will provide up to 150% of the preset current for up to 30 seconds enabling high short term torques during acceleration etc.

Over speed /over current protection: Independent control of either the current or speed loops by external inputs enables torque or speed control applications with overspeed or over current protection.

The demand signal may derive from a potentiometer, 0-10V or 4-20mA. The speed feedback signal may be selected to be the Armature voltage or a shaft mounted Tachometer.
