DC-DC Step Down Step Up Voltage Regulator 0.5-30V 4A Adjustable CC CV Regulated Laboratory Power Supply LCD Display 35W 3A for Solar Battery Charging
Feature:
1. LCD Display: Monitor input/output voltage, output current/power/capacity/time with precision and ease. The buck boost converterfeatures an LCD display that shows real-time information about input/output voltage, output current, power, capacity, and time. Users can easily track and monitor the performance, ensuring optimal usage and preventing any potential issues.
2. Accurate and Fast Adjustment: Enjoy precise and quick voltage regulation with both step-up and step-down capabilities. This step down step up voltage regulator utilizes CNC control technology, allowing users to adjust the output voltage from 0.5V to 30V with precision and speed. Additionally, it supports current limitation adjustment from 0A to 4A, providing flexibility in power delivery for various devices.
3. Reverse Polarity Protection: Prevent damage caused by reverse connection. The step up/down transformer is designed with built-in reverse polarity protection at the input terminal, ensuring that accidental reverse connections do not lead to device malfunction or damage. Users can connect the step up/down transformer without worrying about damaging the equipment due to incorrect orientation.
4. Anti-Backflow Protection at Output Terminal: Streamlined charging process without the need for additional diodes. With the built-in anti-backflow protection at the output terminal, users can charge batteries without the requirement of adding extra diodes. This feature simplifies the charging process while maintaining safety and efficiency.
5. Software Protection Mechanisms and Adjustable Thresholds: Customizable default settings and adjustable protection thresholds. The variable voltage regulator incorporates multiple software protection mechanisms to ensure safe operation. Users have the option to set the module's default behavior (on/off) according to their preference. The module also provides adjustable protection thresholds, automatically shutting off the output when the working parameters exceed the predefined safety limits. With filtering, the output ripple is minimized, ensuring stable and clean power supply for connected devices. The module is equipped with an enhanced heat sink, ensuring efficient heat dissipation and extended product lifespan.









Specification:
Origin: Mainland China
Type: buck (stepdown) regulator
Condition: New
Model Number: DC Buck Boost Converter
Input voltage: 5.0-30V The input voltage is lower than 5.5V, which will affect the voltage measurement accuracy, and the line loss voltage needs to be considered when using it
drop, and the lower the input voltage, the smaller the output power. For example, for 30W output, the input needs to be above 8V
Output voltage: 0.5-30V
Output current: It can work stably at 3A for a long time, and it can reach 4A under enhanced heat dissipation
Output power: natural heat dissipation 35W, enhanced heat dissipation 50W
Voltage display resolution: 0.01V (accuracy ±1%+3 characters)
Current display resolution: 0.001A (accuracy ±1%+5 characters)
It means that the maximum possible error voltage is allowed to be about 0.3V and the current is about 40MA. Of course, the actual situation will be better than this
Conversion efficiency: about 88%
Soft start: Yes (the module with a large power load may fail when it starts)
protection mechanism:
Input anti-reverse connection;
Output anti-backflow;
Input undervoltage protection (4.8-30V adjustable, default 4.8V)
Output overvoltage protection (0.5-31V adjustable, default 31V)
Output overcurrent protection (0-4.1A adjustable, default 4.1A)
Output over-power protection (0-50W adjustable, default 50W)
Over-temperature protection (80-110°C adjustable, default 110°C)
Timeout protection (0-100h adjustable, default off)
Overcapacity protection (0-60Ah adjustable, default off)
