Single/dual-lamp controller BM-DK200

Single/dual lamp controller,according to the platform instructions, achieve separate power supply and power off operation for the connected load (lamp) , LED lamp dimming, lamp electrical parameter acquisition, threshold setting, lamp pole tilt monitoring, lamp pole leakage/tilt detection, street lamp fault judgment, wireless OTA online upgrade and other functions.


Stable lamp control experience

Adopt RS485, power carrier and other communication modes.It has stable communication and high control efficiency. The same level of silicone as the LED street lamp power supply is used for packaging, IP67 protection grade.Strong anti-interference ability, with excellent anti-surge, electrostatic discharge immunity, fast transient pulse immunity, etc. Suitable for harsh outdoor working environment, resistant to high temperature, low temperature, high humidity, salinity, etc.; The intelligent algorithm is used to detect the working state of the street lamp and report the failure of the street lamp, which is convenient for users to monitor and maintain the lamp. No data loss after power failure for more than 10 years
