300W 20A Constant Voltage Current Converter Solar Panel / Wind
Turbines power supply module
Product Description:
Module properties: synchronous rifier non isolated step-down
constant current constant voltage module CV charging module
Scope of application: high power LED constant current drive,
lithium battery charging (including ferroelrics), 4V, 6V, 12V, 14V,
24V battery charging, Ni Cd Ni MH battery (battery pack) charging,
solar panels, wind power generator.
Input voltage: 6-40VDC
Output voltage: continuous adjustable (1.2-35VDC) for a long time
of less than 32V (applied to the application of the input voltage
higher than the output voltage can not be boosted)
Output current: MAX 20A , long time work 15A (long time within the
power tube temperature exceeds 65 degrees with the cooling fan,
high voltage output to the amount of use)
Limit range: 0.2-20A (adjustment) module is more than 65 degrees,
please add the fan.
Lowest voltage difference: 3V
Working frequency: 150KHZ
Conversion efficiency: MAX 96% efficiency is related to the
pressure difference and the use envonment
Output ripple: around 50mV of ripple (without noise) 20M bandwidth
(reference only) input 24V
Working temperature: -10 C to +75 C) (please pay attention to the
temperature of the power pipe in actual use. Please strengthen the
heat or reduce the use of the heat.)
Output short ccuit protion: (instantaneous protion) constant
current (current setting constant current value is not long short
ccuited)
Input back protion: No
Output anti - reverse perfusion: No, for load power or inductive
load needs additional 2 pole tube!
Connion mode: terminal
Module size: 60*53*30MM
The output current regulation method:
adjust the CV potentiometer and set the output voltage to the
voltage you need according to your load requement.
a counter clockwise CC potentiometer of about 30 les (that is,set
the output current to the minimum), conned to the LED, you need to
adjust CC potentiometer current for battery charging, the battery
is fully discharged, the output received again, adjusting CC to the
current you need, (for charging must use a dead battery transfer is
allowed because the battery remaining power increasing, the
charging current is small).
