5. Operation:
The module has two kinds of usage: one is simple mode, another is fully
functional mode. The default is simple mode, if you need fully functional mode,
you can open it by yourself.
5.1 Simple mode
1, Connect the input and output, to ensure that the range of input voltage
requirements, the non-reverse. Input voltage must be higher than the minimum
input voltage.
Note: Input voltage range: 8V ~ 60V;
Input Current Range: 0A ~ 15A
Output voltage range: 10V ~ 120V;
Output Current Range: 0A ~ 15A.
2, Set the desired voltage and current values. It should be noted that no units
display the voltage and current displays last digit decimal point R, the voltage
display value in the second or third decimal place (such as 00.00 / 000.0), the
current value is displayed in the first or second place (such as 0.00R / 00.0R).
Setting voltage and current values as follows:
After power on the default display format of the voltage setpoint is the voltage
value shown is "00.00" and press the "SET" button to switch to the current set
value, the current value display format is "0.00R", press the button Increasing
the setting, press the button to reduce the set value, the decimal point will
move along with the size of the set value, press accurately set, long press can
be quickly set. After the voltage or current value is changed, press the "SET"
key will display "----", indicating that save the voltage or current value of the
current setting, the instrument default storage location for the M0. If there is no
change in the voltage or current value, press "SET" button will switch to the
current or voltage values.
3. After setting press the "OK" button you can export.
4, lower output state when the voltage value is displayed pressing the key to
increase the output voltage, the output voltage can be reduced by pressing the
button, you can press the button to increase the current set value when
displaying the current value, you can press the button Save small current
setpoint, a short press accurately set, press can quickly set. Output state short
press "OK" button you can switch the display of voltage, current, long press 3
seconds can automatically round display, press again to cancel long wheel
significant. In the next round of significant state, press the button invalid.
5, the next output state, press "SET" button to turn off the output.
5.2 Fully functional mode
This module has three special functions, the default is closed, if necessary,
you can open them by yourself.
Function 0:After electricity, it will output automatically.
Function 1: Save and bring up the parameters, display the power and capacity.
Function 2: Take turns to show the parameters after output automatically.
5.2.1 Open/close method
Press the"OK" button for a while, then electricity, the LED will take turns to
show among "--0-","--1-"and"--2-". When displaying "--0-", release the"OK"
button, it will open or close the function 0. When displaying "--1-", release
the"OK" button, it will open or close function 1. When displaying "--2-" , release
the"OK" button, it will open or close function 2. After releasing the "OK" button,
the "--y-" displays in the digital tube indicates that you have already open the
current function, the "--n-" means that you have closed the current function.
1, the output enable function 0 automatically after power-up.
2, enable the function after 1, in the non-output state, press the "SET" button in
voltage "00.00", the current "0.00R", call up the parameter "Lo.-0", save the
parameters "SA.-0" and set the input voltage switching between 00.0
threshold cycle.
(1) Set parameters are stored Recall function:
Such as the need to 10V, 1.5A stored in the memory location 1 and bring up
the storage location 1 parameters.
1. Press "SET" button to switch to the voltage value, the set voltage value
10.00V, press the "SET" button to save the current set voltage value.
2.Press the "SET" button to switch to the current value, the current value is
set the tone for 1.500A, press the "SET" button to save the current current
value.
3.Press the "SET" button to switch to "SA.-0", press the (up or down)button to select
the storage location, where the need to adjust to "SA.-1", press the "OK"
button you can set "10V, 1.5A "stored in the storage location 1.
4.Press the "SET" button to adjust to the "Lo.-0", press (up or down)the button to call
up the parameters to select the desired storage location, where the need to
adjust to "Lo.-1", press the "OK" button brings up the storage location 1
parameters.
5. Native 0 to 9 groups of 10 storage locations, each storage location can be
arbitrarily set voltage and current values, each storage location are
independent of each other.
(2) Set the input voltage protection:
Input voltage protection function is mainly used in solar panels as a power
supply circuit, which is set as follows: Start special function 1, press "SET"
button to switch to 00.0, press the arrow keys to set the voltage value, press
the "SET" button Save the current set voltage value.
For example, your solar panels working voltage is 34V current 8A, you want
to use this power supply the voltage to 48V, 4.5A, to recharge the battery, in
bright light panels can certainly meet the power needs (assuming this is the
maximum power point) But when the sunlight becomes weak, the solar panel
voltage drops, assuming 00.0 at this time is set to 30V, when the input
voltage drops to 30V, the power supply will automatically adjust the output
voltage to ensure that will not be pulled down to 30V or less (ie, to obtain themaximum power).
3, enable the function after 2 output will auto rotate voltage, current, power,
capacity, and other parameters.
Restore factory settings: the power supply is powered on, press the SET
button, power is automatically restored to factory settings
Precautions
1, the module is boosting module, VOUT≥VIN. To the module is powered, in
the absence of output voltage output terminal voltage, output voltage equal to
the input terminal; if the set output voltage lower than the input voltage, output
voltage is also equal to the output of the input voltage, which is a normal
phenomenon, When in use the input voltage must be lower than the output
voltage or the rated voltage of electrical and electronic equipment.
2, high-power electrical appliances to power, turn off the automatic output
function, and then connect the input and output, and then press the "OK"
button output, and wait until the voltage rises to a set voltage, and finally
opened appliances.
3, to charge the battery, turn off the automatic output function, set up the
appropriate charging voltage and current, connect the battery, and then press
the "OK" button output, you can charge the battery.
4, the effective power P = input voltage V * 15A, 900W nominal refers to the
maximum power the module under specific operating conditions, at different
input voltage, the maximum output power is limited by the maximum input
current limit decline. such as,
The input voltage is 20V: Maximum output power P = 20V * 15A = 300W
The input voltage is 40V: Maximum output power P = 40V * 15A = 600W
The input voltage is 60V: Maximum output power P = 60V * 15A = 900W
5, conversion efficiency: about 85% (input voltage, current and output voltage,current affect the conversion efficiency)
