Size (mm):66 (long)* 50 (wide) * 21 (high) Weight: 43 g
Usage:
This module has two kinds of usage: one is simple usage, another is fully functional usage.
Simple usage:
1. Properly connect input, output, and guarantee the input voltage in the range of requirements. It is forbidden to reverse connection, or it will burn out.
2. Setting the voltage and current value, the setting method as follows:
After electrify, the LED default displays the voltage value, the format of voltage display is "00.00", press the "SET" button to switch to the current value, the format of the current value display is "0.000". Press the button to increase the value, press the button reduce the value, short press the button can accurate regulation, long-press the button can quickly regulate. If the voltage or current value has been changed, press the "SET" button the LED display the "----" said that the voltage or the current has been saved. If there is no change of voltage or current value, press the "SET" key to switch to the current or voltage value.
3. After finish the setting, press the "OK" button to output.
4. In the output state, press the button can increase the output voltage value and press the button can reduce the output voltage value when the LED display the voltage value, press the button can increase the current value and press the button can reduce the current value when the LED display the current value,short press the button can accurate regulation, long-press the button can quickly regulate. In the output state, the short press "OK" button can switch display parameters such as voltage, current, power, capacity, long press for 3 seconds will automatically take turns to show, long press"OK" button again can cancel the take turns to show. In the output state, then button is invalid
5. In the output state, press the "SET" button to close the output.
Fully functional usage:
This module has three special functions, the default is closed, if necessary, you can open them.
Function 0:After electricity, it will automatically output.
Function 1: Save and bring up the parameters, display the power and capacity.
Function 2: Automatic take turns to show parameters after output
Open/Close method:
Long press the"OK" button, then to the module electricity, the LED will take turns to show in "--0-"~"--2-", when display "--0-" , release the"OK" button will open or close function 0, when display "--1-" , release the"OK" button will open or close function 1, when display "--2-" , release the"OK" button will open or close function 2. After releasing the "OK" button the digital tube display "--y-" said already open the current function, the display "--n-" said it already close the current function.
1. Enable function 0 it will automatically output after electricity.
2. Enable the function 1, in the condition of no output, press "SET" button will take turns to show among voltage "00.00", current "0.000", bring up the parameters "Lo.-0" and save the parameters "SA.- 0". Below illustrate this function:For example we need store10V, 1.5 A in the storage location 1 and bring up the parameter from storage location 1.
1. Press the "SET" button to switch to the voltage value, setting the voltage value of 10.0 V, press the "SET" button to save the voltage value.
2. Press the "SET" button to switch to the current value, setting the current value of 1.500 A, press the "SET" button to save the current value.
3. Press the "SET" button to switch to the "SA.-0", press the button to select the storage location, here need to adjust to "SA.-1", press the "OK" button to store the "10V, 1.5 A" in the storage location 1.
4. Press the "SET" button to switch to "Lo.-0", press the button to select the storage location which the parameter needs to bring up, here need to adjust to "Lo.-1", then press the "OK" button to bring up the parameters of storage location 1.
5. This module has a total of 0 ~ 9 common 10 groups of storage location, the storage location can be set arbitrary voltage and current value.
6. Enable function 2, after output,it will automatically take turns to display the parameters such as voltage, current, power, and capacity.
Note:
1. Properly connect input and output, it is forbidden to reverse connection, or it will burn out.
2. This module is a step-down module, input voltage needs over output voltage of more than 1.5 V.
3. Output under 2A natural cooling, output above 2A shall strengthen heat dissipation.
Package includes:
1 x Power board
