10 x LED driver constant current power supply step-down Input:5-35V Out:1.25-30V

Description

10pcs x LED driver with constant current power supply step-down Input:5-35V Out:1.25-30V

Specification:

Module parameters
 
Input: IN + input is level, IN-type negative
Output: OUT + output is level, OUT-output negative
 
Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module
 
Scope: High-power constant current LED driver, battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind turbines
 
Input Voltage :5-35V
 
Output voltage:
 
(1) adjustable (1.25-30V continuously adjustable)
 
(2) requires a fixed output (1.25-30V choose between), your purchase, please tell the shopkeeper. (Note: only for volume customers, all of the samples made adjustable voltage)
 
Adjustment method: first the right then the input power (7-35V between) and then a multimeter to monitor and adjust the potentiometer output voltage (usually clockwise turn boost, buck turn counterclockwise)
 
Output voltage: adjustable (1.25-30V no load adjustment) Our default shipping 4.2V voltage regulator for other voltage can be their own (or tell the shopkeeper.)
 
Output current: rated 3A, the largest 4A (more than 15W, please install the heat sink)
 
Constant current range :0-4A (adjustable)
 
Turn lamp current: constant current value * (1% -100%), turn the lamp current value with the constant interaction, such as the constant current value of 3A, turn the lamp current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) When adjusted to the constant current value when the 2A, then turn the lamp current constant current of 0.1 times (0.1 * 2A = 0.2A).
 
Default had already shipped 0.1 times adjusted to
 
Minimum pressure: 2V
 
Output power: natural cooling 15W,
 
Conversion efficiency: 92% (up to 92% (the higher the output voltage, the higher the efficiency)
 
Output ripple: 20M bandwidth (for reference)
 
Input 12V Output 5V 3A 60mV (MAX)
 
Operating Temperature: Industrial (-40  to +85 ) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation)
 
Full load temperature rise: 45
 
No-load current: Typical 10mA (12V switch 4.2V)
 
Load regulation: ± 1%
 
Voltage regulation: ± 0.5%
 
Dynamic response speed: 5% 200uS
 
Indicator: Red LED constant current charging indicator light red, light blue charging is completed
 
Output short circuit protection: Yes, constant current (constant current setting values)
 
Connection: solder wire directly on the PCB
 
Battery use:
 
1 Make sure you need to recharge the battery float voltage and charge current, the module input voltage;
 
2 adjustable constant voltage potentiometer, the output voltage to about 3V.
 
3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current reaches a predetermined charge current value;
 
4 turn lamp current default shipping charge is 0.1 times the charge current (constant value), please adjust the switch for the lamp current adjustment potentiometer; (generally without adjustment)
 
5 adjustable potentiometer allows the output voltage reaches the constant float voltage;
 
6 connected to the battery, try charging.
 
(1,2,3,4,5 take steps to block input power, output load does not take batteries.)
 
LED constant current driver to use:
 
1 Make sure you need to drive the LED current and the maximum operating voltage;
 
2 adjustable constant voltage potentiometer, the output voltage to about 3V.
 
3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current to achieve the desired LED current;
 
4 adjustable potentiometer allows the output voltage constant pressure to achieve maximum operating voltage LED;
 
5 connected to the LED, the test machine.
 
(1,2,3,4 take steps to block input power, output load is not connected LED lights.)
