Module parameters
Scope:High-power LED constant current driver, rechargeable lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charging, solar panels, wind generators
Input voltage:7-40V
Output voltage:continuously adjustable (1.25-35V) (applied to the input voltage is higher than the output voltage applications can boost)
Output Current:8A, 10A maximum time within the (power tube temperature exceeds 65 degrees, please add cooling fan, 24V 12V 5A turn within generally be used at room temperature without a fan)
Constant Range:0.3-10A (adjustable) module over 65 degrees, please add fan.
Turn lights Current:current value * (0.1), turn the lamp current and constant value linkage, such as constant value of 3A, turn the lamp current is set to a constant current of 0.1 times (0.1 x 3A = 0.3A), when the constant 2A, when adjusted to the current value, then turn the lamp current constant current of 0.1 times (0.1 x 2A = 0.2A).
This version is a fixed 0.1 times (actually turn the lamp current value is probably not very accurate) is full of instructions for charging.
Minimum pressure:1V
Conversion efficiency:up to about 95% (output voltage, the higher the efficiency)
Operating frequency:300KHZ
Output Ripple:about the ripple 50mV (without noise) 20M bandwidth (for reference) Input 24V Output 12V 5A measured
Operating temperature:Industrial grade (-40 → to + 85 →) (please note the actual use of the power tube temperature, the temperature is too high, please enhance heat dissipation)
No-load current:Typical 20mA (24V switch 12V)
Load regulation:± 1% (constant)
Voltage Regulation:± 1%
Constant accuracy and temperature:the actual test, the module temperature changes from 25 degrees to 60 degrees, the change is less than 5% of the current value (current value 5A)
Dynamic response speed:5% 200uS
Potentiometer adjustment direction:clockwise (increase), counterclockwise (decrease)
Indicator:color indicator, charging indicator light red, fully charged light green (no load is green)
Output short circuit protection:Yes, constant current (constant current setting values)
Input reverse polarity protection:None,
Output anti-anti-perfusion:no, for charging the battery needs additional two diodes!
Connection:Terminals
Package included
3 x DC-DC Step Down Adjustable Power Supply Module
