As the competition of high-end LED displays tends to be fierce, the uniformity of LED brightness and the strict requirements of color accuracy, the quality of screening LEDs can no longer meet the demand; therefore, point-to-point correction for each LED to enhance the LED display Quality has become a trend. At present, most of the methods of point correction on the market are performed by the controller. However, this method increases the load of the controller and limits the number of LED points that can be controlled. The cost is high and the design of the controller is complicated. Built-in MBI5040 digital point correction new function, can individually adjust the LED brightness uniformity, and avoid the LED chromaticity shift problem that is usually generated during the point correction process. In addition, the point correction operation directly through the MBI5040 allows the controller to focus more on image processing.
Generally, the point correction can be divided into analog type or digital mode. However, point correction by analog method usually causes the problem of LED wavelength shift, that is, LED color shift problem. The main feature of the MBI5040 is 8-bit point correction through digital mode. Under the same visual refresh rate, the brightness of each LED is compensated to ensure that the brightness of the LED can maintain uniform brightness with the brightness of the surrounding environment. There is no need to worry about LED chromaticity shift caused by point correction.
In addition, the MBI5040 has a built-in patent protection circuit design that multiplies the grayscale data by the point correction data. Therefore, when performing point correction, the LED display does not need to sacrifice image grayscale or visual refresh rate. The MBI5040 also provides 16-bit PWM functionality and uses Accumulated Technology's patented S-PWM technology to increase visual refresh rate. The MBI5040 combines 8-bit position correction with 16-bit PWM and maintains a high visual refresh rate, allowing the controller to be designed with lower-order FPGAs, reducing the overall design cost of the controller.
Therefore, through the economical MBI5040, the LED display can be easily upgraded to a high-end LED display, which is especially suitable for indoor and outdoor LED display, LED advertising screen, commercial LED screen and other applications. In addition to the above features, MBI5040 has 16 output channels, which can support a constant current output range of 2mA to 60mA per channel, and withstand voltage up to 17V. In addition, MBI5040 also provides forced error detection, error detection in messages, 7 bits. Current gain, and thermal protection.
24 hours mechanical timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
setting at any time
Instructions:
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.
Caution:
1.D o not exceed the maximum ratings of the timer.
2.M ust reset the current time after power failure.
3.D o not plug the timer directly into the working electrical appliances.
4.U nless changing the setting, keep the program same every day.
5.D o not disassemble timer by yourself. Professionals service are needed for maintenance.
6.T his item is only for indoor use.
