Air Conditioner -DC DC MPPT Step-Down Converter Generic Brand Highlights DC DC MPPT Step-Down Converter Description: 5A constant current and voltage step-down module with MPPT control. Effectively reduce solar battery charging time. Maximum 95% conversion efficiency, improve filling efficiency. Can charge batteries, lithium batteries, etc. and with light control. Power supply for the mobile phone or a variety of digital products, such as a vehicle power supply, driving high-power LED. specification: Properties: Non-isolated Buck Module (BUCK) Input voltage: 6-36V Output voltage: 1.25-32V continuously adjustable (the default output 5V) MPPT voltage adjustment range: 6-36V Current range of output: 0.05-5A (default output current is 3A, within 3A for a long time) Turn signal output range: 0.01-5A (default 0.3A) current range will be a little difference because the parameter error parts. Dual multi-function display: input voltage, output voltage, output current, output power Operating temperature: -40 to +85 degrees Operating frequency: 180KHz Conversion efficiency: up to 95% (efficiency is related to input voltage, output voltage, current and voltage difference) Short circuit protection: Yes Over temperature protection: Yes (output automatically cut off after over temperature) Reverse voltage protection input polarity: None, (if necessary, add the chain in the diode) Output anti-irrigation protection: None, the output must be connected to the battery plus the blocking diode, otherwise it will burn the module Charging indicator: red charging, green fully charged. Turn current sensing light. When using solar panels to supply electricity, the small solar charging current is also very small, less current of the light, it will be green, but it is not not full, please note this distinction. Installation: 3mm screws (4) Connection: Terminals, IN is input, OUT is output Size: 60*31*22 millimeters (L*W*H) Package includes: 1 piece MPPT DC-DC step-down converter Note: The module current detection is the low-end test, please do not directly connect the negative input with the negative output
