Summary
LX39-Z Infrared Motion Sensor Instruction
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,
choosing peace of mind, and choosing safety.
This product has a switching power supply version and a capacitor step-down version. The switching power supply
version has a working voltage of up to 100V-277V and a standby power consumption of <0.5W. In principle, the
capacitive step-down version can only have a single voltage, and the standby power consumption is >0.7W. You should
consider it when choosing a product.
LUX adjustment:
LUX refers to the illuminance of the environment. Adjusting the LUX adjustment knob allows you to choose which
illuminance you want to get the sensor into the induction. Choose the habit that suits you.
Some of the choices in the 20LUX solution are to be illuminated. Some choose 50LUX ambient illumination to be
inductive lighting, and some choose to be inductive lighting at any time, as long as the LUX adjustment knob is
adjusted to the maximum.
Time adjustment:
The time adjustment knob is used to adjust the time after the sensor senses the light, and the user can reasonably
select the delay time after the induction.
