DC-DC 8A Automatic Step-Up Step-Down Buck Boost Adjustable Power Supply Module

Free USPS First Class Shipping. Description: This module can be applied to relatively large fluctuations in the input voltage, the output requirements are relatively stable area. Module Properties: non-isolated synchronous rectifier step-up/step-down module automatically Input voltage: DC5-30V Input Current: 8A (MAX) Peak 10A (can use in Long working hours when input Current :< = 6A) Quiescent Current: 4mA (Operating Voltage Different, There will be errors) Output voltage: DC1.25-30V continuously adjustable Output Current: 10A (MAX) (it can be long time susing when natural cooling output current <=5A) Output current range: 0.2-10A Operating temperature: -40 to +85°c Operating Frequency: 150KHz Conversion efficiency: Up to 91% (efficiency and input and output voltage, current, voltage dropout related) Current protection: yes Short circuit protection: (enter the 10A fuse) double circuit protection, use more secure. Over-temperature protection: Yes (over-temperature automatically reduces the output voltage) Input Reverse Polarity Protection: None (if required in the input string into diode) Output anti-anti-irrigation: Yes, for charging plus blocking diode is not required. Installation: 4pcs 3mm screws Connection: welding output, (V-IN as an input, V-OUT is the output) Module dimensions: 60X53X22mm/2.36X2.08X0.86inch (LxWxH) Output current adjustment method: 1. CV potentiometer adjustment, depending on your load requirements, the output voltage is set to the voltage value you need. 2. CC potentiometer counterclockwise located about 30 laps, (ie, the output current is set to a minimum), connected to the LED, potentiometer CC tune to the desired current. After charging for battery, the battery fully discharged, and then to output, adjust to your desired current CC, (be sure to use for charging batteries completely discharged before being allowed to transfer, because the battery power is left in the more, the charging current is smaller.) Please do not use the short-circuit current way of transfer, the circuit structure of the module can not short-circuit the way transfer Package Includes: 1 x DC-DC 8A Automatic Step Up Step Down Adjustable Power Module 150KHz Payment 1.
