Potentiometer adjustment direction: clockwise (increase), anticlockwise (decrease), the potentiometer ( CV ) closed to the input voltage is used to regulate voltage, the potentiometer ( CC ) closed to the output voltage is used to regulate current ( CC )
Operating temperature: Industrial grade ( -40 Deg.C to +85 Deg.C ) ( Please note the actual use of the power tube temperature, high-temperature heat strengthened )
Indicator: dual color indicator, charging indicator light is red, the green light meansfully charged ( No load is green )
The precision of constant current and temperature: On the actual test, the module temperature from 25 degrees to 60 degrees, the constant current value change is less than 5 pct ( 5A constant current value )
Output short circuit protection: Yes, Constant current ( the current setting constant current value )
Input reverse connect protection: NO
Output prevent reverse flow: NO
Wiring Method: amphenol connector
Fixed turn lamp current is 0.1 times the current value
( Used to identify whether the battery is fully charged When charging ).
Made from a dedicated benchmark IC and the high-precision current sensing resistor, proving a more stable.
Constant current, when 20 Deg.C to 100 Deg.C constant current 1A, temperature drift less than 1pct.
Focus suitable for LED driver.
High output current, the max output current can reach 8A.
Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
Double heat sink design. MOS Schottky diode independent heat sink, which heat dissipation is good.
And won't affect each other.
Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
3296 multiturn potentiometer, high accuracy voltage and current regulation, good stability.
Double color lamp, working condition be clear at a glance.
Voltage and current are adjustable, which effect is good.
