3pcs DC-DC high voltage boost converter 8V-32V to ±45V-390V ZVS step-up booster module capacitor charging power supply module Specifications: Modular nature: Non-isolated boost module Input voltage: 8~32V input(the default is 10~32V input.) Input current: 5A (Max) Output voltage: +45~390V continuously adjustable (default output ±50V) Output current: 0.2A Max(with input, output pressure related,the higher the output voltage, output current is smaller) Output power: 40W (Peak 70W) Working temperature: -40 ~ + 85 degrees (ambient temperature is too high, please enhance heat dissipation) Operating frequency: 75 KHz Conversion efficiency: up to 88% (efficiency and input and output voltage, current, pressure-related) Quiescent current: 15mA (12V liter 50V, the output voltage, the higher the current will increase too quiet) Short circuit protection: Yes.(input 10A fuse, please do not directly short circuit and pull arc! Because it may damage the rectifier device, if you want to do this, please connect the series power resistor to limit current) Over current protection: Yes. (Input current exceeds 4.5A, reducing the output voltage) Over voltage protection: Yes. (Output voltage exceeds 410V, lowering the output voltage) Input reverse polarity protection: Yes (not self-recovery, reverse will burn the fuse, try not to reverse.) Installation: Four 3 mm screws Wiring method: terminal-free welding output Size: 60 x 50 x 20mm Note: The module output is high voltage, on people, animals have life-threatening, the course please pay attention to safety precautions. Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness. Package Includes: 3 x Booster Module
