Specifications: Input: IN + input positive, IN- input negative Output way: OUT + output positive, OUT- output negative Input voltage: 4-38V Output voltage: 1.25-36V continuously adjustable Output current: adjustable, maximum 5A Output Power: 75W maximum Working temperature: -40 to + 85 ??br />Operating frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes (limit current 8A) Overtemperature protection: (automatically shut off the output after overtemperature) Input reverse polarity protection: None, (if necessary, please enter the string into the high current diode) Installation: four 3mm screws Module dimensions: 51 x 26 x 15mm (L x W x H) Features: 1. High power, high efficiency, 5A, low ripple; 2. Triple: (1) Use as a normal blood pressure modules with overcurrent protection capability; (2) As the various voltage lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery) charger for solar panels, wind turbines and other occasions; (3) Used as a high-power LED constant current drive module; 3. With constant pressure and constant current modes, there are light indicates which mode is currently in module; 4. When used as a lithium battery charger, you can set the float voltage and the charge current size, there is light indicates is being charged or has been filled; 5. Has the current limit protection, output short circuit even if it will not burn module. 6. This module uses machine placement, reflow soldering, and each module shipments have been two hours before the aging tests to ensure high reliability. Note: When you use this product, the module inputs and outputs to the ground and do not co-together, this will cause the board power current sense resistor is bypassed, so that the module can not adjust the output current size, the case then load easy to burn power chip module. Package included: 5 x 5A constant current constant voltage LED driver module
