DC-DC 400W High power step-down constant voltage constant current adjustable power module Battery charging LED drive powersupply
Main features of the power module:
 
* 10-60V wide input voltage, suitable for most of the market power supply as input source.
 
* Output constant voltage constant current, continuous adjustable voltage and current. It can satisfy most electrical equipment.
 
* Large output power, good ventilation and natural heat dissipation can achieve 280W/12A (note the output power and output current limit).
 
* Module adopts step rectifier scheme, high efficiency, output voltage above 10V efficiency up to 92-96% ,
 
* Constant current indication when charging the battery. Charging status is clear at a glance.
 
* The input has 15A fuse, the input positive and negative polarity connection will not damage the power supply (will burn the fuse, need to replace the fuse)
 
Module parameters
 
Product model: SZ-BK0612
 
400W step-down constant voltage constant current
 
Module nature: Non-isolated BUCK module
 
Input voltage :10.5-60V
 
Output voltage range: 0-45V (must meet step-down conditions, IN input multiplied by 0.8)
 
Minimum output voltage: 0V( 1V)
 
Maximum output voltage: about the same as the input *0.8 (for example, the input is 40V,40V*0.8=32V)
 
Output constant current: 0.2-15A(continuously adjustable, more than 12A to strengthen the heat dissipation)
 
Maximum output power :400W(fans need to be added for forced cooling of heat sink and magnetic ring)
 
Maximum continuous operating power: 280W(in ventilated environment)
 
Maximum continuous operating current: 12A(in ventilated environment)
 
Input undervoltage protection: yes, (when the input is lower than 10.5V, the output is closed, with about 0.5V error)
 
Input overvoltage protection: None (Forbid overvoltage)
 
Operating temperature: -10~ 85 degrees (more than 65 degrees for heat dissipation)
 
Working frequency: 100KHz
 
Conversion efficiency: up to 97% (efficiency is related to input and output voltage, current and pressure difference)
 
Short circuit protection: (constant current protection)
 
Input reverse connection protection: yes (short circuit need to be cautious input reverse connection will burn the input fuse,)
 
Output anti-back irrigation: none (for charging the battery, the output is connected to inductive load, such as the motor must add anti-back irrigation diode)
 
Working indicator light: Yes (blue LED light)
 
Constant current indicator light: yes (when constant current is working, the CC indicator light on the small board is red, no current output, and this light does not light when constant voltage)
 
Connection mode: built-in 25A wiring terminal without welding
 
Module size: length 60 width 60mm height 45mm
 
Net weight: 170 grams. Add packing 180 grams.
 
Packing: independent carton packing.
 
Wiring: input /IN is the input. "Output /OUT" means output (marked in Chinese)
 
Matters needing attention:
 
* Input, output positive and negative poles are strictly forbidden to connect (input negative connection will burn fuse, output negative connection will damage control board, small board damage can not be repaired, can only be replaced
 
* Control panel has a bit of rain proof glue, if damaged can only be replaced. Mind to take falling
 
* To charge the battery, when the output is connected to the inductive load, the output should be added with an anti-backfilling diode\ \
 
 
Voltage and current adjustment methods: use a multimeter or flat-head screwdriver.
 
 
Voltage regulation: rotate the "CV" blue potentiometer on the power supply board according to the voltage you need, and adjust the voltage clockwise and lower it counterclockwise
 
 
Output current adjustment: the multimeter to 20A or 10A current gear, the power supply voltage to 5V, constant current potentiometer "CC" counterclockwise 20 turns, the current to the minimum multimeter short-circuit output, and then in clockwise adjust "CC" potentiometer current to the required value, (note: When the constant-current potentiometer "CC" turns counterclockwise 20 times, the power supply may have no output voltage, then because the current is adjusted to 0A. Ignore it, turn up the current clockwise and you'll have an output.
 
 
The current detection of the module is low-end detection, please do not short-circuit the input negative pole and the output negative pole directly with wire, short-circuit the negative pole power supply is not constant current, resulting in the damage of the power supply and the electrical equipment that needs constant current.
 
 
Module for buck power supply can only buck, not rise. The input voltage must be higher than the output voltage.
