Features and advantages

working mode

on the marketLEDThe driving circuit is divided into constant current driving type and constant current pulse driving type. Constant current driving circuit is more suitable than constant voltage drivingLEDDue to its unique characteristics, it has been widely used and in recent years, there has been a strong development of constant current pulse drive typeLEDPower Supply. whenLEDWhen using pulse current drive, there are two important indicators to consider: one is the relationship between safe peak current and duty cycle; The second is that under different pulse current driving conditions,LEDLong term light efficiency.N92000Adopting two working modes of constant current and constant current transient, these two modes are as followsLEDPower supply mode, forLEDResearch and development, production, and testing provideapproachActual testing power supply.

Large size high-definition touch screen

N92000adopt8Inch high-definition touch color display screen, standard configuration includes unified settings, voltage settings, current settings, channel viewing, step mode, intermittent mode, memory loading, and system configuration modules. All parameters can be directly set on the touch screen for all channelsON/OFFCompleted on the touch screen.

Modular design, easy to expand and maintain

N92000Adopting modular design, single machine12/24An output interface, each interface containing22Each channel adopts a common anode output, and interfaces are isolated from each other. By customizing wiring connectors to adapt to different types of testing interfaces, the efficiency of instrument use can be greatly improved, greatly reducing the tedious work caused by traditional testing equipment wiring.

Stable signal quality and high output accuracy

There are two working modes: constant current and constant current transient. The product adopts high-precision circuit design, with high current output accuracy, good consistency, and stable and reliable long-term operation. The duty cycle can be set within a range in constant current transient mode3%~97%Pulse frequency range1Hz~20kHzBasically covering all products on the marketLEDThe pulse current range of the type.

Intuitive display interface, more intuitive aging testing process

N92000With an intuitive display interface, it can be displayed on the local high-definition screen and monitored on the upper computer monitoring interface, making the aging testing process clearer and more intuitive.

N92000It can be centrally controlled by the upper computer, and a single channel can be independently programmed for output. The upper computer adopts a classofficeDevelopment style, user-friendly interface, capable of real-time monitoring of voltage and current values in various channels. Pulse output settings can be customized through the "waveform control" interface, with channel parameters such as current amplitude, period, duty cycle, and other parameter settings. Users can directly right-click on a channel and perform various operations on it, such as constant current start, pulse start, protection parameter setting, stop, etc.

application---LEDLarge scale aging testing

N92000The series supports multiple cascaded uses, throughN92000After connecting the network port and network cable to the device, all channels can be operated uniformly in the upper computer software. The interface displays the data feedback of each channel, which can be set to start and stop simultaneously by selecting multiple channels. The parameter settings between channels do not affect each other.

N92000Can be widely applied inLEDIn large-scale aging applications,N92000The open programming interface supports users for secondary development and can integrate instruments into users' automatic testing systems. Users can independently control and age products of different specifications by group.
