The LTG-9807AY is an LED character and numeric display module designed primarily for displaying numeric information, typically in range-finding equipment, inverters, heavy machinery, automotive electric systems, and other equipment.

This module consists of seven-segment digital displays with white segment color, red background color, and a pitch of 0.56 inches (14.2mm). Each digit accepts up to three characters of any combination of Segments A through G and any of the sixteen symbols/numbers in the display. It features an absolute maximum voltage rating of 25V and an electrical power rating of 6W. Additionally, the LED has an operating temperature range from -30 to +70 Celsius and a storage temperature range from -40 to +85 Celsius.

The LTG-9807AY is easy to install and the user can select which character or number to display. For example, the segment A of the third digit can act as a decimal point or a hyphen in order to identify decimal numbers or negative values. To make things even easier, the display is available with a choice of four different mounting methods to suit any application or environment.

The display module contains an array of LED’s (Light Emitting Diodes) which provide the light source to display characters. An LED is a semiconductor device that emits light when a suitable electrical voltage and current is applied to it. The LED emits light in all directions, so special optics are designed to focus the light in one direction only. This is done using special reflectors and lenses, as well as using different color-converting chemicals.

The LTG-9807AY display module can be operated with either a direct current (DC) or alternating current (AC) power supply. When working with DC the display module is driven by a voltage source, typically 13V - 20V, with a maximum of 25V, and supplied with a current of up to 4A.The display module can also be powered from an AC power source through a bridge rectifier. An AC supply voltage ranging from 5V to 15V is the standard, but this range can be increased using a step-up DC-DC converter.

The display is activated with a signal applied on the input pin of each character. After the signal is applied, the character is illuminated and the LED that is associated with it will light up. The brightness of the LED can also be adjusted based on the amount of current applied on its input pin. The LED will stay lit until the signal applied on the pin is removed or its power supply is interrupted. In addition, the LED can also be set to blink at various rates, depending on the design of the system.

The LTG-9807AY display is an excellent choice for displaying various kinds of information such as data, numbers, letters or symbols. It offers reliable and bright performance in a variety of applications and works great for displaying information in an attractive and attractive manner. The module is highly cost-effective, making it an attractive solution for range-finding, automotive, electrical and instrumentation applications.
