1. CNC voltage and current adjustment, convenient and fast, industrial quality, high precision, can be directly used in engineering projects. 2. Professional power liquid crystal is adopted, with clear interface, simple operation and almost perfect protection. 3. Hardware protection: anti-reverse connection protection of input terminal, reverse connection does not burn; Short circuit protection of output terminal, short circuit does not burn; Anti-backflow at output terminal, no additional anti-backflow diode is needed when charging the battery. 4. Software protection: over-voltage protection (OTP), over-current protection (OCP), over-power protection (OPP), over-temperature protection (OTP), input under-voltage protection (). 5. The default adjustment voltage or constant current value can be set, which can be quickly adjusted in applications. CNC Up-down constant voltage constant current power supply. Voltage and current can be locked to prevent misoperation! Full of materials, stable performance and wide range of uses. Input voltage:DC 5.0 V-30V (under 4.7V, there is undervoltage protection ,it is recommended that the input voltage be higher 7v, when the input voltage is lower than 7V, the output power decrease, the lower the input voltage, the smaller the output power) Output voltage:.6V-30V Output Current:0-4.0A Output power:35W under natural heat dissipation and 50W under air cooling Voltage accuracy:0.5%+1 word,Resolution:0.01V,factory calibrated accuracy Current accuracy:0.8%+3 words,Resolution:0.001A,factory calibrated accuracy Conversion Efficiency: about 88% Soft start:Yes Input reverse connection protection:Yes,reverse connection does not burn Output anti-backflow:Yes, can be directly connected to the Output short circuit protection:Yes, it can be directly short-circuited to the output terminal Temperature Protection(OTP):Yes,100# Operating frequency:180KHZ Colour:White Material:Plastic Package Contents: 1 * Adjustable Regulated Voltage Power Supply Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
