Features: The Automatic Voltage Regulator Module is the solution for stable and precise voltage control, making it a must for any DIY electronics enthusiasts or professional electrician. With its programmable and adjustable features, this module allows users to fine-tune their voltage output to suit their specific need, ensuring optimalreliability. Designed for anyone who requires accurate voltage regulation, from hobbyists to engineers and technicians, this module is suitable for professional use. Whether you're working on a complex electronics project, testing equipment, or simply need to ensure stable voltage output during power fluctuations. Its durable plastic construction ensures long-lasting use, making it a smartinvestment for anyone looking to improve their voltage regulation capabilities. Specifications: Material: Plastic Input voltage: 5.0-30V The input voltage is lower than 5.5V, which will affect the accuracy of voltage measurement, and line loss voltage drop need to be taken into account when using, and the lower the input voltage, the smaller the output power. For example, 30W output, input need more than 8V Output voltage: 0.5-30V Output current: It can work stably in3A for a long time, and can reach4A under enhanced heat dissipation Output power: naturalheat dissipation 35W, enhanced heat dissipation 50W Voltage display resolution: 0.01V1%+3Digits Current display resolution: 0.001A1%+5Digits The maximumerror voltage is allowed to be about 0.3V and the current is about 40MA, the actual situation will be better than this Conversion efficiency: about 88% Working Frequency: 180KHZ Size: Approx. 7.9x4.3x2.6cm Note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
