1200w 20a dc converter Booster power module in 8-60 V 12-83V with heat sink 1200 W 12v to 24v 48v 1200 W 20a DC
3800/=

Specifications:
Input voltage: 8-60v
Input current: 20a static
Current: 15ma (12v L 20v, the higher the output voltage, the current increases too quietly)
Output voltage: 12-80v continuously adjustable
Output current: 20a max exceeds 15a, please improve heat dissipation (input and output pressure are related, the greater the pressure, the smaller the output current)
Constant range: 0.5-20a
Output power:
Input voltage *20a, for example: input 12v*20a=240w, input 24v*20a = 480w,
Input 36v * 20a = 720w, 48v * 20a = 960w, input 60v * 20a = 1200w
If you need more power, you can use two modules in parallel. For example, B. Output to 30a, the two modules can be used in parallel.
The current of each module can be set to 15a.
Operating temperature: -40 to +85 degrees (the ambient temperature is too high, please improve the heat dissipation)
Operating frequency: 150khz
Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current and pressure)
Overcurrent protection: When downcurrent regulation, the output current limit can be adjusted. If the current exceeds the current limit, the output current will automatically be reduced to the minimum 5a, which varies according to the type of load current
Short circuit protection: Yes (input 20a fuse)
Double short circuit protection, safer use.
Input backconnect protection: none, (if necessary, please string in diode)
Output counter fill: Yes, no charging plus blocking diode required.
Installation: Four 3mm screws
Connection: crimp terminal output

Overweight bass low pass plate

This price is empty plate, without any components on the board

The subwoofer processing circuit, also known as the low-pass filter, is connected to an ordinary pure post-power amplifier to form a subwoofer power amplifier. This board adopts high quality double-sided glass fiber board, reasonable wiring, moderate material, carefully built, minimal noise. The frequency adjustment range is 22Hz-210Hz.

Power supply voltage: AC double 15V

Board size: 80mm long and 40mm wide

The spacing between potentiometers is about: 42mm

Potentiometer from left to right are: frequency adjustment, volume control

Product features:

1.4 LED light display power, non-working state intelligent automatic shutdown;

2. Built-in lithium battery protection IC, over-current, over-voltage, under-voltage protection;

3. Dual USB output;

4, motherboard size: thickness 8mm* width 32mm* length 69mm.

Basic product parameters:

Input port: MicroUSB (Android port)

Input requirements: 5V constant voltage power supply can be used as charging input power supply, matching the charger is more than 5V1A

Output port: USB

Output parameters: 5V1A/5V2A

Requirements for rechargeable batteries:

Available battery: 18650 battery, mobile phone battery, flat battery, MP3 battery and other 3.7V-4.2V polymer lithium battery, can be single (piece) power supply, can also be multiple (piece) parallel power supply (does not support series, can not be series). (Note: Parallel increase capacity, series is to increase voltage, can only be used in parallel!)

Can parallel 2-6 18650 batteries!!

Unavailable battery: dry battery, battery, 1.2V rechargeable battery, NIMH battery, 3.2V lithium iron polymer lithium battery, etc.

Product installation should pay attention to the following points:

1, the battery should be in parallel, the voltage should be between 3.2-4.2V to work, 18650 flat head and polymer batteries can be;

2, the battery is connected to the motherboard B+ negative B-, install the motherboard will burn;

3, new and old batteries, models and brands are inconsistent batteries can not be mixed.
