Leite introduces five 0.1%-100% deep dimming LED power supplies

Recently, Leite Technology has introduced four types of constant current dimming driver power supplies of DAIL, 0-10V, DMX and thyristor. These four types of five models are: thyristor dimming power supply (TD-50-500-1750-E1P1), five-in-one 0-10V dimming power supply (AD-50-500-1750-F1P1), DMX512 Dimming power supply DMX-50-500-1750-F1P1, DALI dimming power supply (DALI-50-500-1750-F1P1/) and 6 in 1 DALI dimming power supply (DALI-50-500-1750-F1P2).

Leite's new 50W dimming power supply uses ABS+PC engineering flame retardant plastic, full protective white casing, five models of dimming power supply size is unified to 133mm (length) × 90mm (width) × 30mm (height), the overall appearance is simple Generous, silk screen logo is clear and easy to use! Below, let's take a look at the main advantages of these five new power supplies.

1, T-PWM digital dimming

These five dimming power supplies use Leite's own T-PWM digital dimming technology, which does not change the electrical performance of LEDs like analog current adjustment, so that the color rendering index of LEDs changes and affects LED life. -PWM digital dimming technology not only maintains the best color rendering index and best life of LED lamps , but also achieves perfect dimming effect.

The whole machine adopts digital circuit design, and multiple power supply current errors are extremely small, the consistency is high, and the light is more uniform.

2, deep dimming, no stroboscopic

Five dimming power supplies are built with high-performance MCU digital program processing, challenging the constant current power dimming limit difficulty, achieving 0.1%-100% deep dimming, and the light dimming process is naturally delicate and slowly brightened up and dark. Can be close to the same dimming effect as traditional incandescent lamps, unlike ordinary dimming power dimming from dark to bright dimming suddenly starting from a relatively high brightness or not extinguished, it suddenly flashes, plus a unique tone The light curve, the dimming is smooth and natural, without any stroboscopic, making the visual experience of the human eye more comfortable.

The high dimming performance is the main feature of the Leite dimming power supply.

3, wide voltage, digital current selection

Leite's new 50W dimming power supply input voltage is 100-240VAC, output voltage is 10-54VDC, constant current output: 500mA-1750mA, can achieve fast DIP dial switch 8-speed current selection, different from most manufacturers' dialing code The switch is a hard-cut current method. It is pure hardware. Several output currents are provided through different resistor combinations. The error of current accuracy is caused by the error of hardware parameters, and the consistency between power supplies is also poor. The code switch will affect the current accuracy through a large current for a long time, which will seriously cause the power failure and no current output.

The Leite DIP switch does not pass current, but only informs the MCU program to output the specified current as a command switch. The current is output by digital means, which minimizes the error caused by the hardware. The digital degree of the whole machine is extremely high, and it is easy for the general power supply. The difference in current affected by high and low temperatures is also minimized. In the case of wide voltage and wide current output designs, the digital power supply of Leiter is better in current accuracy and consistency.

In addition to the choice of 8 regular currents, the customer's specific current requirements are also supported, and also play the characteristics of digital power, so Leite is equipped with an ISET advanced interface for users to support any user's own current value selection, as long as the power supply range The current value inside can be arbitrarily selected.

Multi-lamp current output voltage + W can be matched different power, a very wide scope to meet different current and voltage of different manufacturers having led lights, LED lamps to avoid the problem of matching categories brought Alternatively, while saving the cost of procurement, Reduce purchase inventory; one model can replace more than ten LD dimming power supplies from other manufacturers on the market.

4, high PF, high efficiency, in line with EMC, safety requirements

Built-in active power factor correction function (active PFC), PFC: PF>0.99@110V, PF>0.95@230V, efficiency>85%, total harmonic THD<10%, current accuracy: ±3%. It meets the requirements of safety and EMC certifications such as CCC, UL, CE, SAA, GS, and CB.

The new Leite 50W LED dimming power supply is an isolated power supply that meets SELV safety extra low voltage standards, meets CLASS 2 power supply standards, is safe and reliable, and has short-circuit, over-temperature, overload, no-load, over-voltage protection and other safety protection functions. The fault is automatically restored, which can prevent accidental safety situations and ensure the service life of LED lamps and led power supplies more reliably.

Other features:

*5 models of power supply support PUSH DIM reset switch dimming interface, you can easily dim the LED with an ordinary button switch.

* SCR dimming power supply built-in high-performance MCU digital program processing, can achieve a maximum 0.1-100% dimming range, in the history of thyristor power supply has not been, and Reiter rewrite this history.

*DMX512 power supply supports RDM remote management protocol. It can realize remote read and write DMX address like DALI power supply. It can write address after power supply is installed. It is also convenient to change the address later. It is not necessary to climb the ceiling to reset the sky as usual. .

*5 in 1 0-10V dimming power supply (AD-50-500-1750-F1P1) This model has two dimming terminal interfaces, 1-10V and PUSH DIM dimming interface, of which 1-10V interface supports: 0- 10V, 1-10V, 10VPWM, adjustable resistors, 4 kinds of dimming mode access, plus PUSH DIM a total of 5 in 1 dimming function, very powerful and convenient.

*6-in-1 DALI dimming power supply (DALI-50-500-1750-F1P2) This model has three dimming terminal interfaces, DALI, 1-10V, PUSH DIM, of which 1-10V interface supports: 0-10V, 1-10V 10VPWM, adjustable resistors, 4 kinds of dimming mode access, plus DALI, PUSH DIM, a total of 6 in 1 dimming function, is also very powerful and convenient.

At present, the above five power supplies have been put on the market, and are sold to all regions of the world through the distributors of Leite. With excellent quality, they have been applied in many five-star hotels and large-scale projects, and the performance is different. And user praise!
