DC Buck Boost Converter Upgraded Color Screen CNC Stabilized
Voltage Regulator Power Module Constant Voltage Constant Current
Notice:SK40 Without FAN
Features:
1. High quality material, prevent the failure of the key after long-term use, protect the circuit board solder pad from oxidation, improve the PCB conductivity, reduce the line impedance and contact resistance
2. Independent silicone button to set voltage or current, one key to enter, one key to exit, fast and simple, refuse cumbersome
3. With 1.8 inch large color screen display content more intuitive, more simple operation Settings
4. The performance is improved, the power is upgraded, and the external fan port can be extended
5. Silicone button material is soft, comfortable to touch, feel excellent. Compared with the mechanical keys can withstand long time use and frequent press, without wear or failure, more durable, longer service life.
