Part Number: TJ0460
Lot number: 2022
Featured Service: Charging Module LED Driver
Specifications: 300W 20A
Module parameters:
Module nature: synchronous rectification non-isolated step-down constant current constant voltage module CC CV charging module
Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind turbines
Input voltage: DC6-40V
Output voltage: Continuously adjustable (1.2-35 VDC) for a long time below 32V (suitable for applications where the input voltage is higher than the output voltage cannot be boosted)
Output current: maximum 20A, within 15A for a long time (if the temperature of the power tube exceeds 65 degrees, please add a fan to dissipate heat, and if the high voltage output, please use it in derating)
Limit viewership of range: 0.2-20 A (adjustment) module exceeds 65 degrees, please add a fan.
Minimum pressure difference: 3V
Working frequency: 150KHZ
Conversion efficiency: up to about 96% efficiency depends on the pressure difference and the operating environment
Output ripple: ripple about 50mV (excluding noise) 20M bandwidth (for reference only) input 24V measured
Working temperature: -10 ° C to + 75 ° C) (Please pay attention to the power tube temperature in actual use. If the temperature is too high, please strengthen heat dissipation or derating use)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Output short circuit protection: with (instantaneous protection) constant current (the current setting constant current value cannot be short-circuited for a long time)
Input reverse connection protection: none,
Output anti-reverse perfusion: none, for the load with its own electrical or inductive load, an additional diode is required!
Wiring method: terminal block
Module size: 60 * 53 * 30MM
Net weight: about 85 grams
Output current regulation method:
1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.
2. Set the CC potentiometer about 30 turns counterclockwise (that is, set the output current to a minimum), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after discharging the battery, connect it to the output, and adjust the CC to the current you need. (When used for charging, be sure to adjust it with the discharged battery, because the more power left in the battery, the smaller the charging current.)
Wiring instructions:
OUT +: output positive
OUT-: output negative
+ IN: Enter positive
-IN: enter negative number
CV: output voltage regulation
CC: Output current regulation
EN: Enable, output off at low level; pause, active at high voltage level
When the input and output are grounded, no-load CV output constant voltage, CC output constant current
