shipped within one bussiness day

Specification:
Working voltage: DC12V.
Working current: DC12V 52mA
Size:63*38mm

Function:
The setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast,
when the input voltage is greater than the reference voltage, the relay is closed (11-10 closed, 11-12 disconnected), when the input voltage is less than the reference voltage, relay does not operate.
To compare respectively input voltage signals A and B, when the voltage signal A is greater than the voltage signal B, the relay is closed (11-10 closed, 11-12 disconnected), when the voltage signal A is less than B voltage signal
The setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast, when the input voltage is less than the reference voltage,
the relay is closed (11-10 closed, 11-12 disconnected), when the input voltage is greater than the reference voltage, after the electric appliance does not work.

The Reference Voltage:
Voltage reference module (1 or 2-3 input voltage value) after precision resistor divider, input voltage value determines the range of the reference voltage value,
Such as the input voltage is 12V, then the reference voltage adjustable range is 0-12V

Module Purpose:
The automobile circuit hardware, industrial equipment, laboratory testing, application testing circuit.

Package Included:
1 x  2-Channel Voltage Comparator Module

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.
