This is an Adjustable Synchronous Step-down module a DC to DC buck converter module with an input voltage range of 6.5V-60V and an output of 1.25-30V. This output is variable and can be varied using the on-board multi-turn potentiometer.

High efficiency up to 90%. 5-40V adjustable input voltage range. With over-current and over-temperature protection, safe for use. It uses high performance fixed frequency current control mode controller as the core. Suitable for Battery chargers, home automation, and other high voltage electrical equipment.

This is a 5A power module DC-DC step-down module 24v/12V to 5V power converter module. With synchronous rectification scheme, wide voltage, high current, and high efficiency.

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).

High efficiency up to 90%. 5-40V adjustable input voltage range. With over-current and over-temperature protection, safe for use. It uses high performance fixed frequency current control mode controller as the core. Suitable for Battery chargers, home automation, and other high voltage electrical equipment.

This module adopts boost and buck chip as the main controller, external 60V 75A MOS tube as the switch tube, double 60V 5A SS56 schottky rectifier, 60V voltage withstand value, more stable and reliable performance, is a good adjustable step-down/up constant voltage constant current solution. Parameter:Input Voltage: 5.5-30V (If the input voltage is 5V, measurement is not accurate. Less than 4.7V, low-voltage protection.)Output Voltage: 0.5-30VOutput Current: 3A for long time stable work, can be up to 4A after enhancing heat dissipation.Output Power: 35W in natural heat dissipation, up to 50W after enhancing heat dissipation. Output Indicator: Constant current indicator light, output indicator lightVoltage Display Resolution: 0.05VCurrent Display Resolution: 0.005ATransfer Efficiency: Approx. 88%Soft Start: YES (High power load module may fail when started)Input Reverse Protection: YESOutput Anti-Backflow: YES, No additional anti-backflow diode is required for battery chargingShort Circuit Protection: YES, After short circuit protection, the module automatically shuts down the output, and be restored after re-energizing.Low-Voltage Protection: The default is about 4.7V, the output will be automatically disconnected if less 4.7V.Operating Frequency: 180KHzSize: 66x48x21mm (LxWxH)Mounting Hole: 4mm Constant Current Mode:CC sets the potentiometer for the current and rotates clockwise to increase the setting current and counterclockwise to reduce it. When the load current reaches the set current, it enters the constant current state and CC constant current indicator (red) lights up.
