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: 4mmConstant 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.Package Include:1 x Step-Down/Up Power Converter Module ## Features - Buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current range is 0-3A, can be arbitrary adjustable, if enhance heat dissipation, it can reach 4A; max output power is 35W, if enhance dissipation, it can reach 50W. - LCD Display: the voltage regulator module is designed with LCD, can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A. - Safe Protection: the volt transformer board is with reverse connection protection at input terminal, reverse connection will not burn; stop the current from feeding back protection at output terminal; short circuit protection. - Button Control: button control output voltage ON / OFF status, and you can set the default output state is ON or OFF of the next time power-on. - Application: the switching power supply can be used as an ordinary buck-boost module with over-current protection; used as a battery charger; used as a high-power LED constant current driver module. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07LCMHCV9 | | Best Sellers Rank | #31,142 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #550 in Power Supplies (Computers & Accessories) | | Brand | REES52 | | Brand Name | REES52 | | Country of Origin | China | | Current Rating | 4 Amps | | Customer Reviews | 4.0 out of 5 stars 114 Reviews | | Importer Contact Information | REES52 | | Included Components | 1 x Buck Boost Converter Display | | Item Dimensions D x W x H | 5D x 5W x 5H Centimeters | | Item Type Name | Buck Boost Converter Display Module | | Item Weight | 90 Grams | | Manufacturer | REES52, REES52 | | Manufacturer Contact Information | REES52 | | Minimum Frequency | 50 Hz | | Model Number | REES-RS1863 | | Mounting Type | Chassis Mount | | Packer Contact Information | REES52 | | Part Number | REES-RS1863 | | Power Source | Battery Powered | | Power Source Type | Battery Powered | | Product Dimensions | 5D x 5W x 5H Centimeters | | Specification Met | REACH | | UPC | 302703031511 | | Unit Count | 1 Count | | Warranty Description | Contact Manufacturer | ## Product Details - **Brand:** REES52 - **Power Source:** Battery Powered - **Product Dimensions:** 5D x 5W x 5H Centimeters - **Mounting Type:** Chassis Mount - **Current Rating:** 4 Amps ## Images ![REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Image 1](https://m.media-amazon.com/images/I/71x2mn4brgL.jpg) ![REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Image 2](https://m.media-amazon.com/images/I/81h9ODwOchL.jpg) ![REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Image 3](https://m.media-amazon.com/images/I/71vYojmQhoL.jpg) ![REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Image 4](https://m.media-amazon.com/images/I/715RsBRlK3L.jpg) ![REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Image 5](https://m.media-amazon.com/images/I/71FKmAQs0jL.jpg) ## Questions & Answers **Q: Can i use in rc plane insted of ubec ?** A: Function wise you can, but its weight is much more than a UBEC. **Q: Is this work for battery pack of mine 3s 18650 lithiem oin battery 12v and 7500 amh?** A: yes **Q: Can we run 24hrs this module which is connected to12v input?** A: Is you can withen it's operating range But I I suggest put a small fan to keep temp.
