Cllena DC 24V Step Down to 12V 100A 1200W DC/DC Voltage Converter Regulator Waterproof Buck Transformer Power Supply

Wiring: OUTPUT+ to LOAD+, OUTPUT- to LOAD-; INPUT+ to BAT+, INPUT- to BAT-

Note:
* Never connect to solar panel, PWM/MPPT charge controller, inverter or wind turbine.
* Never charge the battery. Keep good air convection.
* Never reverse the polarity.
* Use the enough big cable to avoid the voltage drop.

Application:
24V DC battery as input power to 12V DC appliances as output load.

Questions:
How to choose the correct current for loads?
For example, if the max current of your load device is 10A, then choose 10A/ 0.8 = 12.5A at least for resistive loads according to international standard.
If the load device is motor or compressor, then you may choose 10A/ 0.5 =20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.
