Product Description

B3603 LM2596S 4 Digital DC-DC Constant Voltage Current Step-Down Module 6V-40V to 0-36V 0-3A

features:

 Cnc module dollar b3603 DC-DC is a completely digital dollar display module, small size, high power, high efficiency, stable.
 adhered to the microcontroller precision measurement at high speed and calculation, the output voltage and current value can be precisely adjusted, integrated 10 memory locations groups, can be stored at any time, recall parameters, easy to use.
 With four digits eight segment LED digital tube, you can view the voltage, current, power, capacity and other parameters in real time. Meanwhile, the module has an automatic output after power on and automatic rotation function of display parameters, etc., can be switched on or off depending on the need of use.

 minimum display resolution capacity: 0.001ah
 output ripple: <= 50mV
 Weight: 43g

Description of the display:

 00.00: voltage value, 00.00 ~ 36.00v
 0.000: current value, 0.000 ~ 3.000A
 P.000, P0.00, p00.0, P000: power value, unit w, decimal variations point position with changes in power position. for example: p.123 means 0.123w, p1.23 means 1.23w, p12.3 means 12.3w, P102 means 102W.
 C.000, c0.00, c00.0, C000: value of capacity, unit ah, position of the decimal point has changed with the change in capacity. for example: c.123 means 0.123ah, c1.23 means 1.23ah, c12.3 means 12.3ah, C123 means 123ah.
 –0–, –1–, –2-: Special features 0, 1, 2
 –y-: open the special features
 –n-: close the special function
 sa.- * (* means 0 to 9): save the parameters to the storage position of 0-9 in any place a storage
 lo.- * (* means 0 to 9): memorized recall locations 0-9 arbitrary set of parameters

use:

 connect the input and the correct output, check that the input voltage is within the required range, the opposite is strictly prohibited, if you are afraid of damage reversed you can chained more than 3a diode.

how to set the voltage and current values:

 1. Default startup display is nominal voltage value. display of the voltage value as “00.00”, unit is “v”. press the “set” key to pass the current value, the display format of the current value is “0.00”, the unit is “a”, press the button to increase the set value, press the button to decrease the value, press briefly set correctly, long press can set quickly.
 2. After setting is completed press “OK” button for the exit.
 3. Under the output status when displaying the voltage value press the button can increase the output voltage, pressing the button can reduce the output voltage. press the button to increase the current setting value when the current value is displayed, press the button may down current setting, briefly press the setting accurately, long press can quickly setting. under the output status press “short; ok” button to change the display voltage and current value, long press “ok” for 3 seconds to automatically rotate the new display, long press to cancel the rotation display. on the rotation display, pressing the keys is invalid.
 4. under the exit status, press the “set” button to turn off the output.
 above are a simple model of the form, which is the default mode, can see that it is very simple and easy to use, if you want to save the recall stored values, or see the power, capacity and other parameters in the output state, it needs to conversion in full function mode.
