3. Function Description:
3.1. Module has IN / OUT, ON / OFF two buttons: IN / OUT button to switch the input voltage and output voltage display, long press to switch the output current output power display; ON / OFF button control output ON or OFF, long press Set power on default output status is ON or OFF.
3.2.CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, CC constant current indicator (red) lights up; the right CV is the voltage setting Potentiometer, clockwise rotation, can increase the output voltage. ON indicator is the output status indicator, when the output voltage is on, otherwise off.
4. How to use:
4.1. Used as an ordinary buck-boost module with over-current protection capability
(1) Adjust the CV constant voltage potentiometer so that the output voltage reaches the voltage you want.
(2) Measure the output short-circuit current with 10A current meter (connect the two test leads directly to the output end), and adjust the CC constant current potentiometer to make the output current reach the preset over-current protection value. (For example, if the current value displayed by the multimeter is 2A, the maximum current will only reach 2A when you use the module. When the current reaches 2A, the red constant voltage and constant current LED is on, otherwise the LED is off)
Caution: When using in this state, there will be a voltage drop of 0 ~ 0.2V due to the current sampling resistor at the output. At the same time, the input and output leads will have a certain linear voltage drop This is a normal phenomenon!
4.2. Used as a battery charger
Without constant current function of the module can not be used to charge the battery, due to the power of the battery and the charger pressure drop is large, resulting in charging current is too large, causing damage to the battery, so the beginning of the battery to use constant Flow charging, when the charge to a certain extent automatically switch back to constant voltage charging.
(1) Determine the float voltage and charging current for which you need the rechargeable battery (if the lithium battery parameter is 3.7V / 2200mAh then the float voltage is 4.2V and the maximum charging current is 1C, ie 2200mA)
(2) Under no-load condition, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the float voltage. (If the 3.7V lithium battery is charged, adjust the output voltage to 4.2V)
(3) Measure the output short-circuit current with 10A current meter (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer so that the output current reaches the predetermined charge current value;
(4) Connect the battery, charging.
(Steps 1, 2 and 3 are as follows: input termination power supply, the output is not connected to the battery load)
4.3. Used as LED constant current driver module
(1) Make sure you need to drive the LED operating current and the maximum operating voltage;
(2) Under no-load conditions, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the maximum operating voltage of the LED.
(3) with a multimeter 10A current measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current reaches the predetermined LED operating current;
(4) connected to the LED, test machine.
(Steps 1, 2, and 3 are as follows: Input the power and output the no-load LED.)
Note: This module is more than 3A, 35W use, please strengthen the heat! ! !
5. Note:
5.1. Module input IN- Prohibit short circuit with output OUT-, otherwise constant current function will be invalid.
5.2. Please make sure that the power of the power supply is greater than the power required by the output load!
5.3. If the module is to be fully loaded with output, the input voltage should be over 8V. When the input voltage is 5V, the output power is about 15W, and the voltage ammeter fails. Module current value 4A, the premise subject to the maximum output power, such as the output 17V, the current should not exceed 2A.
Purchasing & Delivery
Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
