1989candy AC 220V Electromagnetic Motor Speed Controller Pinpoint Regulator (JD1A-90)

Description

Colour:Jd1a-90 Specifications: Input speed: 1 rpm Output speed range: 1 Excitation voltage: DC90V Excitation current: 5A Velocity change rate: ≤3% Steady Speed Accuracy: ≤1% Input voltage: AC 200-240V Material: PP Panel size: 21*15cm/8.27*5.91" Installation Size: 95*130*186mm/3.74*5.12*7.32" Input voltage: 220V 50Hz Speed: 0-1500 (rpm) Optional model: JD1A-90 Speed adjustable range: 440-1320 RPM Control motor power: 45-90 kW Maximum output: DC 90V 8A Operational instructions: 1. Turn off the power supply and make sure the connection is correct according to the wiring diagram. Do not modify it arbitrarily. 2. Set the external speed knob to "0" before use to avoid instantaneous high current and damage the controller. 3. This product is controlled by generator feedback voltage. The control line is divided into "Blue" and "Yellow". 4. When the motor connection is found that the torque or speed does not meet the requirements, US-52 adjusts the side fine-tuning potentiometer (speed setting adjustment). 5. In order to change the direction of motor operation, only the jumper of CCW and CW on the terminal seat on the back of the controller should be replaced. * When changing direction, the motor must be completely stopped before it can be changed. 1) Choose COM and CW short connection, then the motor rotates clockwise; 2) Choose COM and CCW short connection, then the motor rotates counterclockwise. 6. The action switch only controls the motor to operate or stop, and does not interrupt the power supply. If it is not used for a long time, please turn off the power supply.
