Silicone buttons are soft and comfortable to touch. Compared with mechanical buttons, they can withstand long-term use and frequent pressing without wear or failure, more and longer service life. Input voltage: DC 6.0-36V, output voltage: DC 0.5-36V, output current: 0-4.5A, output power: 40W, voltage resolution: 0.01V, current resolution: 0.001A, voltage accuracy: ±0.3% + 3 words (calibrated), current accuracy: ±0.5% + 3 words (calibrable), conversion efficiency: 88%. Larger and clear color LCD display prevents segment loss after long-term use. In addition, it can protect the circuit board pads from oxidation, improve PCB conductivity and reduce line impedance and contact resistance. DC -boost converter has a built-in buzzer to provide multiple protection alarm reminders. Input reverse connection protection, output backflow protection, undervoltage protection, overvoltage protection, overcurrent protection, overpower protection, overtemperature protection, overtime protection, overcapacity protection, and overenergy protection., Manufacturer: Akfldms
