7S115C : NEW DRIVE SYSTEM FOR LOW SPEED PM DC MOTORS.
-
Power supply 115V- 50/60 Hz
- PWM (pulse width modulation) technique for the speed regulation.
-
Operating frequency 18 Khz : that means fine speed regulation, long life for the motor brushes and silent operations.
- Speed reference : ten turns potentiometer (manual operation) or external current signal 4-20 mA (automatic operation).
- Smooth acceleration of the motor to avoid shock for the load
- Current limited : protection of the motor and max torque for the load known
- Thermal protection to ensure no overload long time operations
-
Overload current protection to avoid damage to the drive system if the motor is stalled for few seconds.
- Alarm LED indicator
- R x I compensation to ensure the constant speed operation in the whole range of load.
- Easy calibrations with trimmers on the board (minimum and max speed, acceleration ramp, RxI compensation) .
- Inhibit input to stop the motor without switch-off the power supply.
