LETAOSK 35W 4A Adjustable Buck Boost Converter Display Constant Current Voltage Voltage Regulator Module

Condition: 100% new Color: Blue&Black Material: Plastic&Metal Size: approx. 6.6x4.8x2.1cm(2.6x1.9x0.8 inch)(LxWxH) Model: ZK-SJVA-4X Working Voltage: DC 5.5V-30V Output Voltage: DC 0.5V-30V Working Current: 30mA Output Current: 4A(4A need heat sink, 3A is stable for long time) Output Power: 50W (50W need heat sink, 35W is for 3A) Voltage Display Resolution: 0.05V Current Display Resolution: 0.005A Conversion efficiency: About 88% Work frequency: 180KHz Item included: 1 x 4A Power Supply Module 1 x Heat Sink 4 x clip Suitable for: Ordinary power supply, Battery charger,LED drive power,Instrument voltage display,Test meter,Circuit test,Power conversion Note: 1) All dimensions are measured by hand, there may be small deviations. 2) It is a DC power module,So it can not connect to AC power. 3) Please make sure input power is more than load power. 4) Please stop output power if module is hot. 5) Input undervoltage protection voltage is 4.7V. Module need re-power if input less than 4.7V. 6) ”IN-”and”OUT-”can not be connect together,otherwise module can not support constant current output. 7) Module need re-power after short protection. 8) Please connect input before connect battery when use as charge and make sure output voltage is higher than battery voltage. 10) Please read use manual and description before use. Feature: 1) It can be used as ordinary buck power supply module, charger and LED constant current driver. Simple and efficient, practical. 2) High voltage resistant terminal, with LCD screen HD display. 3) Support display input voltage,output voltage, current, power..
