Dual LCD dial display enables you to hold the output voltage and battery voltage value at any time.2. Fault prompt function. In addition to different sound prompts, it can also be displayed more intuitively from the display screen (for example, battery undervoltage, battery overvoltage, overload, high working temperature, output short circuit, etc.).3. The overload delay closing function is added in the product to solve the sensitive problem of protection when the soluble electrical appliance is started.4. The small power non profeional user market has increased the positive and negative pole return protection function.5. ligent temperature control oil sealing fan. When the is working, it can work at a certain temperature, which is more energy-saving and quieter.6. Dial MCU control, output wave type, more accurate frequency, accurate output voltage, fast response of protection circuit.Descriptions1.This is a power ,using STM-chip technology and kinds of ligent protection,high reliability.2.Widely used in cars, steamboats, mobile offering post and telecommunications, public security, and other field.Package Included1 x Power 1 x Alligator clip1 x arette
