Feature: 1. The product is simple and easy to operate, small in size and convenient to carry 2. With a variety of software protection mechanisms, and the protection threshold is adjustable 3. After the module's working parameters exceed the protection threshold, the output is automatically turned off 4. The LCD can display input/output voltage, output current, output power, capacity, and output time 5. Professional design and reasonable structure, wiring is simple and convenient Specification: Item Type: DC Power Supply Model: XY5008L Material: Plastic Purpose: Display power supply voltage rise and fall Input Voltage: DC 6.0-55V (extreme low voltage 5.5V, extreme high voltage 60V) Output Voltage: DC 0V-50V Output Current: 0A-8.1A Output Power: 0-400W Typical Output Ripple: Vpp 150mV Voltage Resolution: 0.01V Current Resolution: 0.001A Voltage Accuracy: 0.4% + 1 digit Current Accuracy: 0.5% + 3 digits Capacity: 0-999999AH Energy: 0-999999WH Time: 0-1000 hours Product Size: Approx. 79 x 42mm / 3.1 x 1.7in Setting Interface (how to use): 1. Long press the rotary encoder button for 3 seconds to enter the setting interface 2. Adjust the parameter size using the rotary encoder potentiometer, supports rapid rotation (rapid increase/decrease), short press the rotary potentiometer button to switch the parameter to be adjusted 3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum operating time (OHP) interface, short press the "ON/OFF" button to select the corresponding function on or off; if off, it will display "br" 4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the "ON/OFF" button to select the capacity range 5. After setting the parameters, press and hold the encoder potentiometer button for 3 seconds to exit the setting interface; the setting parameters are automatically saved Package List: 1 x DC Power Supply
