Features: The projection screen controller control set adopts a brand microcontroller with independent programming design, diverse functions, remote control and manual functions, to meet the different usage requirements of customers in different scenarios. Controller circuit is designed with resistance capacitance vosltage reduction, which is inexpensive and has superior performances. The remote control adopts the EV1527 encoding chip, which has 20bits that can pre burn and write 1 million sets of internal code combinations. The repetition rate is very low, eliminating the possibility of interference caused by multiple sets of the same product being used at the same time. Thoughtful base design can be fixed in a convenient place for you to use, making it easy to take and not easily lose. Widely used in various fields, in addition to electric curtains, it can also be used on other devices such as sunshades, projection screens, electric doors, retractable doors, and garage doors.
