Specificatii
REGLAJ TENSIUNE SI
CURENT
Description:
Input Voltage: 5-35V
Rated Output Current: 3A
Output Voltage: Continuously
adjustable from 1.25V to 30V
Ouput current: Continuously
adjustable from 0.1A to 3A
The dropout voltage: 1.5V, because
of reducing module, in order to ensure the output steady. Please
keep the minimum 1.5V pressure difference.
This product with the charge
constant current indicating lamp, the charge indicator lamp, lamp
current adjustable ultra small volume.
Size: 48mm (L) *24mm(W)
*11.4mm(high), not containing potentiometer (including the
potentiometer height 13mm).
Module nature: 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 charge, NiCd and NiMH
battery (batteries) charge, solar panels and wind
generators.
Output voltage:
1.Adjustable continuously (1.25-30V
adjustable);
2.Requires fixed output (between
1.25-30V arbitrary choice).
Adjustable mode: Connect the power
correctly(7-35V), and then monitor the output voltage use
multimeter, and potentiometers (generally, clockwise turn boost,
inverse to buck).
Output voltage: Continuously
adjustable (1.25-30V load regulation).
Maximum output current: 3A, (more
than 15W install fins please).
The dropout voltage: 2V
Output power: Natural cooling
15W
Efficiency: 92% (maximum 92% (the
higher the voltage, the higher efficiency)
Output ripple: 20M bandwidth (only
for reference)
Input 12V output 5V 3A 60mV
(MAX)
Working temperature: industrial
grade (-40C to +85C) (environmental temperature exceeds 40 degrees,
please reduce power use, or to strengthen dissipate
heat).
Full temperature: 45 ?
The no-load current: typical 10mA
(12V 4.2V)
Load regulation rate: +
1%
Voltage regulation rate:
0.5%
The dynamic response speed: 5%
200uS
Indicator: Constant flow indicator
light is red, charging light is red, after charging indicator light
is blue.
Output short circuit protection:
Yes, constant current (setting the value of the constant
current).
Connection: Wire can welded in PCB
directly.
Battery charging methods:
1. Determine the float voltage and
charging current that you need to charge battery and module's input
voltage.
2. Adjustable constant
potentiometer, the output voltage is regulated to about
3V.
3.Use multimeter 10A current block
measurement output short circuit current, meanwhile adjusting the
constant current potentiometer to make output current reaches
predetermined current value.
4.The charging turn lamp current
default is 0.1 times of charging current (current value ).If you
need, adjust turn lamp current potentiometer please (generally do
not adjust).
5. Adjustable constant potentiometer
to make the output voltage to the floating charge
voltage.
6.Connect battery, to try charging
(1, 2, 3, 4, 5 steps is the module input power, output no-load not
connected to the battery).
LED constant current driving use
methods:
1. Determine you need to drive LED
operate current and maximum working voltage.
2. regulation constant
potentiometer; 2, the output voltage is regulated to 3V.
3.Use multimeter 10A current block
measurement output short circuit current, meanwhile adjusting the
constant current potentiometer to make output current reaches LED
operating current
4.Adjustable constant potentiometer
to make the output voltage to the LED maximum working
voltage.
5.Connected to the LED, try test
machine. (1, 2, 3, 4 steps is the module input power, output
no-load not connected to the LED lamps).
