LX-PR-S15-Z Infrared Sensor Instruction
Summary
This product is an advanced digitally controlled infrared pyroelectric intelligent sensor product.It uses the MCU
to accurately calculate the switch information, and accurately controls the relay to be turned on at the zero
point of the sine wave, so that each load is turned on. At the zero point of the sine wave, the inrush current
problem caused by the conventional control mode when the sine wave high voltage is turned on is avoided,
especially the large current damage relay generated by the large-capacity capacitor under the impact of the
high voltage under the load.Due to the diversification of current electrical loads, especially LED lamps,
energy-saving lamps, and fluorescent lamps all have capacitors with different capacitances. This is a disaster
for relays. Sometimes a 50W LED lamp can generate surge currents of 80 to 120A. The 10A ordinary relay can
only withstand 3 times of the inrush current, and it is likely that the relay will be broken in a few days or several
times. This is why the conventional sensor on the market has a short life and a small load current.
In order to overcome this problem, this product adopts advanced digital precision calculation to turn on the load
when the sine wave is at zero potential, thus solving the load surge current problem, greatly enhancing the
load capacity and prolonging the service life of the product. The latest control method of mass production
sensor technology can easily control any load. It is a medium and high-end product. Although the cost is
increased compared with the conventional version, the reliability and life of the product are greatly increased.
This product is equal to choosing peace of mind, and choosing safety.
