Quiescent current: 0.02a (standby) PWM duty cycle: 1 percent -99 percent PWM frequency: 12kHz module: zs-x1a dimensions: 70 x 39 x 31 mm features: 1. Resettable fuse: will turn-off automatically when it is overcurrent. The fuse can self-rest after power-off and few seconds' cooling. So it allows stable performance and small heating. 2. Power supply reversed protection: the module will not burn even when its positive and negative pole of input are connected reversely. 3. Adjust the potentiometer in clockwise direction for increasing and in anti-clockwise direction for decreasing. When you adjust potentiometer in anti-clockwise direction till its max width, you would turn off power supply output. 4. Aluminum shell prevents it from easily damaged. There are holes in its sides and bottom, making it easier to install. Also, it adopts FR4 double panel and reasonable circuit arrangement for more stable performance. How to use: connect this device with lamp or work equipment or electric circuit and rotate the knob for dimming, speed, voltage, temperature control. Main application: especially suitable for regulation of low-voltage electric wire fever, such as: cutting Styrofoam, epe, Raincoat production, galvanocautery painting, and etc. Note: the speed controller is only suitable to control brush motors.
