Features PROTECTION: This DC-DC 12V high voltage boost converter supports short circuit protection, overcurrent protection, overvoltage protection and reverse input protection. APPLICATIONS: Our capacitor charging boost regulator is widely used in capacitor charging, power supply for solenoids and electronic devices, voltage or glow tube test power supply and so on. INSTALLATION: You only need four 3mm screws with no solder terminals to install this 8-32V to 45V-390V high voltage converter module. VOLTAGE REGULATED: Our ZVS boost boost converter modules are voltage regulated with a non-isolated boost module. The output voltage does not vary with the input voltage. NOTE: Be careful! This ZVS boost boost converter is not an isolated boost module. The output voltage is high and dangerous for humans and animals. Specifications: Input Voltage:(2 options, select through the jumper wire on the back of PCB) a, 8-16V b, 10-32V(default) Input Current: 5A(Maximum) Quiescent Current: 15mA(will be higher when 12V to 50V) Output Voltage: ±45-390V(default ±50V) Output Current: Maximum 0.2A(associated with input, output voltage) Output Power: 40W(Maximum 70W) Working Temperature: -40 to +85 degrees (ambient temperature too high, please strengthen cooling) Frequency: 75KHz Conversion Efficiency: 88%(max) Short Circuit Protection: Support(please do not pull short circuit arc directly at output. Direct short circuit arc is likely to damage the rectifier devices. Please connect power resistors in series to limit current) Over Current Protection: Support(reduce output voltage when input current is over 4.5A) Over Voltage Protection: Support(reduce output voltage when it is over 410V) Reverse Input Protection: Support(fuse) Installation Method: Four 3mm screw No-welding terminals Suitable for: 1, Capacitance charging, or power supply of electromagnetic gun. 2, Power supply of electronic equipment. 3, Test power supply of voltage or glow tube. 4, Hunting and deratization. Package includes: 1 x Boost Module Note:  1. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering Package List
