DZS Elec DC-DC 4A 60W Automatic Step-Up Down Power Module 5V-30V to 0.5V-30V Adjustable Constant Voltage and Current Voltage Regulating Current Limiting Converter Board

Feature: Name: Automatic Step-Up Down Power Supply Module - Constant Voltage and Current Adjustable Input Voltage: 5V-30V Output Voltage: 0.5V-30V Output Current: 3A for long time steady operation, up to 4A after enhancing heat dissipation Output Power: natural heat dissipation 35W, enhanced heat dissipation 60W Output Ripple: 20mV voltage ripple for 12V 3A output, and the common module is more than 100mV Transfer Efficiency: Boost 87% - 91%, buck 87%-90% (It may changes on the basis of differential voltage and load. ) Working Frequency: 180KHz Input Over-Current Protection: 10A Fuse Input Reverse Connection Protection: High efficiency MOS type Input Low-Voltage Protection: YES Output Over-Current Protection: YES Module Size: 69x28x21mm Product Performance: 1. Can step up/down voltage, or adjust output current limiting. 2. Constant output current: Input 5V-30, can charge for battery/lithium battery/No. 5 rechargeable battery, adjust the brightness of constant current LED. 3. Can set constant current value without multimeter: It is more easier to set constant current value with a measured single-turn potentiometer. 4. Ultralow output ripple voltage: Low ESR capacitor and two-level filter, suitable for audio, power amplifier board, artificial circuit charging. 5. Safe protection: MOS type input reverse connection protection, input low-voltage shut-down protection, input over-current protection and so on. 6. Charging indicator light: Red and blue light for constant current charging, blue light for constant voltage charging, Blue and green light for close to fully charged, green light only for fully charged. Package Include: 1pcs 4A Step-Up and Down Power Module - Constant Voltage and Current
