ZK-4KX DC DC Buck Boost Converter CC CV 0.5-30V 4A Step Down Step Up Voltage Regulator Adjust Regulated Laboratory Power Module

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 ChargingFeature:1. LCD Display:Monitor input/output voltage, output current/power/capacity/time with precision and ease. The buck boost converter features an LCD display that shows real-time information about input/output voltage, output current, power, capacity, and time. Users can easily ck and monitor the performance, ensuring optimal usage and preventing any potential iues.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 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. Re Polarity Protection:Prevent damage caused by re connection. The step up/down nsformer is designed with built-in re polarity protection at the input terminal, ensuring that accidental re connections do not lead to device malfunction or damage. Users can connect the step up/down nsformer without worrying about dam the equipment due to incorrect orientation.4. Anti-Backflow Protection at Output Terminal:Streamlined charging proce without the need for additional s. With the built-in anti-backflow protection at the output terminal, users can charge batteries without the requirement of adding ex s. This feature simplifies the charging proce while maintaining safety and efficiency.5. Protection Mechanisms and Adjustable Thresholds:Customizable default settings and adjustable protection thresholds. The variable voltage regulator incorporates multe 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 s 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 diipation and extended product lifespan.Specification:Origin: Mainland ChinaType: buck (stepdown) regulatorCondition: NewModel Number: DC Buck Boost ConverterInput voltage: 5.0-30V The input voltage is lower than 5.5V, which will affect the voltage measurement accuracy, and the line lo voltage needs to be considered when using itdrop, and the lower the input voltage, the smaller the output power. For example, for 30W output, the input needs to be above 8VOutput voltage: 0.5-30VOutput current: It can work stably at 3A for a long time, and it can reach 4A under enhanced heat diipationOutput power: natural heat diipation 35W, enhanced heat diipation 50WVoltage display resolution: 0.01V (accuracy ±1%+3 characters)Current display resolution: 0.001A (accuracy ±1%+5 characters)It means that the maximum poible error voltage is allowed to be about 0.3V and the current is about 40MA. Of course, the actual situation will be better than thisConversion efficiency: about 88%Soft start: Yes (the module with a large power load may fail when it starts)protection mechanism:Input anti-re 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)
