DC Buck Boost Power Supply Module Programmable Adjustable Automatic Step UP Down Voltage Converter LCD Display

👍The DC boost converter is made of high-quality ABS and aluminum, which is exquisite in appearance, durable and excellent in performance. LCD can display input and output voltage, output current, output power, output capacity and output time. 👍The numerical control adjustment is accurate and fast, and the voltage can be increased or decreased. The zk-4kx module can be numerically adjusted, accurate and fast. The charging and step-down output voltage can be adjusted arbitrarily from 0.5-30V, and the limit current can be adjusted arbitrarily from 0-4A. 👍During use, our boost converter has safety protection, and the input terminal has anti-reverse connection protection, and the reverse connection will not burn out, so please use it with confidence. 👍Input voltage: DC 5V-30V; Output voltage: DC 0.5V-30V; Output current: 0-4.0A. The output terminal is anti-backflow, and there is no need to add an anti-backflow diode when charging. 👍The module can be set to be turned on/off by default, with low output ripple and π-type filter, applicable to: ZK-4KX buck-boost can be used to charge solar batteries.
