Adjustable PWM DC Motor Speed Controller 4.5V-28V - Reliable & Durable Electrical Equipment for DIY Projects, Robotics, and Household Appliances

Feature:1. PWM DC motor speed controller with switch function.Small size, low power consumption, fast response.2. High power high efficiency, It is precise and reliable with good long‑term stability. With fixing screw hole, convenient for install and fixed.3. Working voltage can be switched to 4.5V‑28V by bridging the connector marked 4.5V‑35V4. The product working voltage is DC4.5V‑28V, output current is 0‑5A, output power is 90W (large), quiescent current is 7u A (standby state), PWM duty cycle is 1%‑100%.5. Using high‑quality materials, strong and durable, has a long service life.Specification:Item Type: Speed ControllerWorking Voltage: DC4.5V-28VOutput Current: 0-5AOutput Power: 90W (large)Quiescent Current: 7u A (standby state)PWM Duty Cycle: 1%-100%PWM Frequency: 20khzPackage List:2 x Speed Controller2 x GasketNote:The input of the DC motor speed controller is direct current, and cannot be directly connected to alternating current (for example: household 220V alternating current), otherwise it will burn out! ! !Do not connect the positive and negative terminals of the DC power supply in reverse, otherwise the governor may be damaged.The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the lin
