The 300W 20A DC-DC Step-down Adjustable Constant Current Module can be used to get adjustable output voltage ranges from 1.2V to 36V. The module provides a wide range of current output up to 20 A. With the heat sink mounted it can easily manage to run high power applications continuously (provided that for continuous high power output you need to use a cooling fan on the heat sink).

Features:

• Scope: High-power LED constant current driver, rechargeable lithium batteries 4V, 6V, 12V, 14V, 24V battery charging; nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators.
• Output voltage: continuously adjustable (1.25-36V) (applied to the input voltage is higher than the output voltage applications can boost).
• Turn lights Current: current value * (0.1), turn the lamp current, and constant value linkage, such as the constant value of 3A.
• Turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).
• This version is fixed 0.1 times (actually turning the lamp current value is probably not very accurate) is full of instructions for charging.
• Minimum pressure: 1V.
• Output Ripple: about the ripple 50mV (without noise) 20M bandwidth (for reference) Input 24V Output 12V 5A measured.
• Operating temperature: -10 to + 75 (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation).
