Features: 1. Conversion efficiency up to 95% (efficiency is related to input and output voltage, current, pressure). 2. Overcurrent protection: Reduces flow regulation, adjustable output current limit, current exceeds current limit, and output current automatically drops to a minimum of 5A, depending on the nature of the load current. 3. Short circuit protection: (Input 20A fuse) Double short circuit protection, safer to use. 4. Output power: input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W, input 36V * 20A = 720W, input 48V * 20A = 960W, input 60V * 20A = 1200W. 5. Connection: no solder terminal output. Specification: Input voltage: 8-60V Input current: 20A Quiescent current: 15mA (12V liters 20V, the higher the output voltage, the higher the current, the quieter) Output voltage: 12-80V continuously adjustable Output current: 20A MAX. More than 15A, please strengthen the heat (input, output pressure related, the higher the pressure, the smaller the output current) Constant range: 0.5-20A Operating temperature: -40 to + 85 ℃ (the ambient temperature is too high, please strengthen the heat) Working frequency: 150KHz Input reverse polarity protection: None, if necessary, enter the string into the diode Output counter fill: Yes, not required for charging plus blocking diodes Installation: four 3 mm screws Size: 13.3 * 5.5 * 5cm / 5.2 * 2.2 * 2.0in Weight: approx. 256g Package list: 1 * Module 1、Conversion efficiency up to 95% (efficiency is related to input and output voltage, current, pressure) 2、Overcurrent protection: Reduces flow regulation, adjustable output current limit, current exceeds current limit, and output current automatically drops to a minimum of 5A, depending on the nature of the load current 3、Short circuit protection: (Input 20A fuse) Double short circuit protection, safer to use 4、Output power: input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W, input 36V * 20A = 720W, input 48V * 20A = 960W, input 60V * 20A = 1200W 5、Connection: no solder terminal output
