LTS Series Driver is a high-performance LED driver that provides smooth, continuous <5% dimming for virtually any LED fixture, It provides constant current CCR dimming mode. It can work in either the phase cut dimming mode or the 0-10V dimming mode, providing integrated products from multiple dimming products.
The LED current is allowed to be set and is programmed by the GUI port.
It is the most versatile LED driver offered today due to its compatibility with a wide
variety of LED arrays, multiple form factors, and numerous control options.

YG Programmer PC Based Software, USB Interface
Programmable Output Current (POC): Programmable Iout from 100mA to 500mA.
Programming Tool:
The YG Programmer is a programming and configuration tool for YG intelligent programmable LED drivers. It consists of the YG programmer which is connected between the USB port of a computer and the LED driver being programmed, and the YG programmer software. The YG programmer software is a PC based graphical user interface that allows the user to program and configure the operating parameters of an YG Programmable LED Driver. This interface allows the operator to set the LED drivers output current within its specified range.
YG Programmer:
Is the physical USB unit connected between the USB port of a computer and the LED driver being programmed? This unit also provides all power required to the LED driver being programmed. No connection to an AC power source is required for programming the LED driver.
YG Programmer Software:
The YG Programmer software is the windows based GUI that allows the user to assign custom part number(s) to the LED driver being programmed. The user can then save the profile to a computer disk and recall as need. The user can then use the "Auto Program" feature to quickly program as many LED drivers with the saved profile as is required. Each driver programming simply requires a click of the mouse to program in a single step.
The YG Programmer software supports bar code scanners. The barcode scanner can be used to automate the programming of the attached LED driver. The barcodes scanner interface also provides an option to either enable or disable logging of the parameters to an excel file.
PC programming mode is through the programmer PRG-01A two wires connected to the driver, by the GUI interface automatically complete the operation, there are engineering mode and factory mode. This mode requires the programmed driver to power on.
NFC programming mode is through the programmer PRG-02A (hand-held) or PRG-02B (seat), automatically completed by the GUI interface, there are engineering mode and factory mode. This mode requires the antenna window of the driver to be near the programmer.
