ARCELI 2Pcs 1.8v 3v 5v 6v 7.2v 12v 2A 30W Low Voltage DC Motor Speed Controller PWM 1803BK 1803B Adjustable Driver Switch

Item features: Input supply voltage: 1.8V-15VDC. Maximum output power: 30 W. Maximum continuous output current: 2A. Duty cycle adjustable: 0% -100%. Size: approx. 32 x 32 x 15 mm / 1.25 x 1.25 x 0.59 inches. Net weight: approx. 14 g. Note: DC motor speed controller DC supply, do not connect directly to 220V AC in the household. Please allow 1-3 mm deviations due to manual measurement. Connect a voltage of 1.8V-15V DC to the circuit, and pay attention to the correct polarity of the connection. Note that the voltage applied to the motor is the supply voltage applied to the circuit. It is recommended to add an appropriately sized fuse in conjunction with the positive supply to protect the circuit from possible short circuits. You can now control the speed of the motor via a potentiometer. Important notes: To ensure safe operation, it is recommended to use a fuse with reasonable rated power (slightly higher than the maximum expected amperage). The controller is secured with a 2A fuse to restore its own performance. It will be damaged if the supply voltage is connected with incorrect polarity. Check all connections before turning on the power supply and turn off the power supply before making changes to the wiring Package Content: 2 x 1.8 V 3 V 5 V 6 V 7.2 V 12 V 2 A 30 Watt Low Voltage DC Motor Speed Controller PWM 1803BK 1803B Adjustable Driver Switch
