The whole network alone section of the aluminum substrate boost DC-DC constant voltage constant current power supply module
Power imported power management chip design, high reliability, surge current, small size (length width 42MM * 70MM * High 13MM) up to 96% efficiency, maximum power 250W. At the same aluminum plate design and easy installation, the back panel can be directly attached to the flat metal cooling. Reducing equipment space.
(Voltage regulation resistance is 10K, current regulation is to 4.7K)
[Module Name] 250W boost constant current module
[Module properties: non-isolated step-up module (BOOST)
[] Input voltage: DC8.5V-48V
[] Input current: 10A (MAX) exceeds 8A please enhance heat dissipation
[] Quiescent current: 10mA (12V liter 20V, the output voltage is higher Shizuta current will increase)
[] Output voltage: 10-50V continuously adjustable
12-80V fixed output (for volume customers)
[Output current]: 10A MAX exceed 6A please enhance heat dissipation (input, output related to pressure, the greater the pressure the smaller the output current)
[Constant] Range: 0.2-8A
[Output]: = input voltage * 10A, such as: input 12V * 5A = 60W, input 24V * 5A = 120W,
Input 36V * 5A = 180W, input 48V * 5A = 240W,
For even more power, two modules can be used in parallel, such as the output to 10A, two modules can be used in parallel,
The current per module can be adjusted to 5A.
[] Working temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)
[] Operating frequency: 150KHz
[] Conversion efficiency: up to 96% (efficiency of input and output voltage, current, pressure related)
Overcurrent protection []: Yes (input exceeds 13A, automatically reduce the output voltage, there is a range of errors.)
[] Input reverse polarity protection: Yes, (less than 5A such as the need for more in the reverse current in the input string into the diode)
[] Installation: four 3mm screw holes
[Wiring]: Wiring Output
[Module] Size: length 70mm width 42mm height 13mm
[Module] Single: 50g
First, the output voltage / current adjustment method:
1, adjust RV1 potentiometer, according to your battery or LED, the output voltage is set to your desired voltage value. 10 LED string voltage regulator such as 37V.
2, adjust RV2 potentiometer clockwise 30 laps, the output current is set to a minimum, connected LED, adjust RV2 potentiometer to the desired current. After the battery for charging, the battery fully discharged, and then to output, you need to adjust RV2 current (for charging must use a battery completely discharged before being allowed to adjust, because the battery charge remaining in Vietnam more, the charging current is smaller.) Please do not adjust the current short-circuited manner, the circuit structure of the booster module can not be short-circuited by way of transfer.
Applications:
1, DIY a regulated power supply, 12V can be input, output can be 12-50V adjustable.
2, the power supply for your electronic device, according to your system can set the output voltage value.
3, as the vehicle power supply for your laptop, PDA or digital products supply.
4, DIY a laptop mobile power supply: 12V coupled with a large-capacity lithium battery pack, so your books can light where they go.
5, solar panel regulator.
6, to the battery, rechargeable lithium batteries.
7, driving high-power LED lights.
