If you need more power, you can use two modules in parallel, such as the output to 30A, two modules can be used in parallel, The current per module can be adjusted to 15A. Working temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation) Operating frequency: 150KHz Conversion efficiency: up to 95% (efficiency and input and output voltage, current, pressure related) Overcurrent protection: Yes (with reduced flow adjustment, adjustable output current limit, current exceeds the current limit, the output current is automatically reduced to a minimum 5A, vary according to the nature of the load current will be.) Short circuit protection: Yes (input 20A fuse) double short circuit protection, the use of more security. Input reverse polarity protection: None, (if necessary, please enter into the diode) Output Counter filling: Yes, for charging plus blocking diode is not required. Input voltage: 8-60V Input Current: 20A Quiescent current: 15mA (12V liter 20V, the output voltage, the higher the current will increase too quiet) Output voltage: 12-80V continuously adjustable Output Current: 20A MAX Over 15A, please enhance heat dissipation (input, output pressure related, the greater the pressure the smaller the output current) Constant Range: 0.5-20A Output Power: Input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W, Enter 36V * 20A = 720W, input 48V * 20A = 960W, input 60V * 20A = 1200W Installation: four 3mm screws Connection: solderless terminals output Colour:As shown in color Material:metal Package Contents: 1 * DC Converter Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
