Description Feature: OUT, CV and CC indicator light Digital display, convenient and easy to use Constant voltage and constant current state One key to save voltage and current value Adjust output voltage and current value accurately 10 groups of storage location, free storage and bring up Automatic/manual switch voltage, current, power, capacity and other parameters display It can be set whether automatically output or not after electrify It can be set whether take turns to show voltage, current, power and capacity or not after output Specification: Input voltage: 6V ~ 40V Output voltage: 0V ~ 36V Output current: 0A ~ 3A Conversion efficiency: up to 92% The output ripple: ≤50mV Working temperature: -40°C ~ +85°C Working frequency: 150KHz Short circuit protection: constant current Voltage regulation/display resolution: 0.01V Current regulation/display resolution: 0.001A The minimum display resolution of power: 0.001W The minimum display resolution of capacity: 0.001AH Input reverse connect protection: no, if necessary please install diode Connection mode: terminals Size: 66 x 50 x 21mm Weight: 44g 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 be burn out. 2. Setting the voltage and current value,the setting method as follows: After electrify, the LED default display the voltage value,the format of voltage display is "00.00", press "SET" button to switch to the current value,the format of current value display is "0.000". Press the button 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 "SET" key to switch to the current or voltage value. 3. After finish 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, 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,the and 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 Turn ON/OFF 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 the 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 "SET" button to switch to the voltage value, setting voltage value of 10.00 V, press "SET" button to save the voltage value. (2) Press "SET" button to switch to the current value, setting current value of 1.500 A, press "SET" button to save the current value. (3) Press "SET" button to switch to the "SA.-0", press the or button to select the storage location, here need to adjust to "SA.-1", press "OK" button to store the "10V, 1.5 A" in the storage location 1. (4) Press "SET" button to switch to "Lo.-0", press the or button to select the storage location which the parameter need 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 total of 0 ~ 9 common 10 groups of storage location, the storage location can be set arbitrary voltage and current value. 3. Enable the 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 be burn out. 2. This module is a step-down module, input voltage need over output voltage more than 1.5 V. 3. Output under 2A natural cooling, output above 2A shall strengthen heat dissipation Package included: 1 x LED display step down module Detail Image Payment 1.We accept PayPal only. 2.All major credit cards are accepted through secure payment processor PayPal. 3.Payment must be received within 7 business days of auction closing. 4.We ship to your eBay or Paypal address.
