Backgrou nd monitoring software It can remotely dim and switch the lights, display street lighting fault information, monitor electrical parameter, summarize and manage the data. Supports maximum output power of 72W (36V / 2A), LED driver has up to 1MHz switching frequency Single pin on / off and brightness control can be finished by using DC voltage or PWM. It assembles AC/DC power supply, centralized dimming function, fault monitoring and feedback, electrical parameter monitoring, lightning protection and other functions. HVDC central ized control cabinet Single cabinet maximum capacity is 60kW, power supply radius is about 3km. Three phase AC power through the HVDC centralized control cabinet, transfer to 204~288Vdc DC, then pass the output control switch floating supply power to lamp, DC-DC LED driver power is responsible for converting DC power into constant current source, which is LED lamp’s requirement to achieve lighting and dimming functions. HVDC centralized control cabinet’s major component is input and output power distribution unit, rectifier module, monitoring unit, and SPD.
Led driver controller constant current power high voltage mod#
Applying a voltage between 0V and 1V on the MOD pin sets the duty cycle. The output frequency is determined by this master oscillator and an internal frequency divider, NDIV, programmable to eight settings from 1 to 16384. A single resistor, RSET, programs the LTC6992’s internal master oscillator frequency. The LTC6992 is part of the Timer Blox® family of versatile silicon timing devices.
The LTC6992 is a silicon oscillator with an easy-to-use analog voltage-controlled pulse width modulation (PWM) capability. The driver features thermal shutdown protection that becomes active whenever the die temperature exceeds 150C. The PWM/EN input allows the device shutdown and the LED brightness adjustment by using an external pulse width modulation (PWM) signal.
The device ensures an accurate and regulated current in the LEDs independent of supply and LED forward voltage variation. The LED pin is compatible with high voltage up to 25 V, allowing the driving of long strings of LEDs. The LED current is set by an external resistor connected to the R SET pin. It requires no inductor, provides a low noise operation, and minimizes the number of components.
