Information

Lifud clients who have been following its products for a long time probably know that the reason why Lifud can provide them with fast delivery service is that Lifud has standard stock system for its finished products. Nowadays, harder as the delivery of tri-proof light LED driver becomes, Lifud tri-proof light LED driver has been the first choice on the European market by virtue of its spot stock.

 

 

 

 

Then what kind of tri-proof light LED drivers can Lifud provide for its clients? Today we are gonna have a fundamental analysis on the differences of isolated & non-isolated tri-proof light

LED drivers and how to choose them.

 

Lifud EU-Standard linear or tri-proof light LED driver solutions

 

Lifud tri-proof light LED driver solutions can be divided into non-isolated & non-dimmable version, isolated & non-dimmable version, non-isolated & dimmable version and isolated & dimmable version. And all of them have features of conforming to the latest ERP standard and harmonic current emissions standard, flicker-free effects, certifications required in different countries (ENEC, CB, CE, RCM and CCC), emergency lighting certification (EL) and various power options from 4W to 90W.

 

①Non-isolated & non-dimmable version

 

LF-FMRxxxYS, Lifud classical non-isolated linear or tri-proof light LED driver, has been sold all over the world for more than 1.8 million pcs within 4 years. It has features of 92% high efficiency, 4 models (LF-FMR20/40/60/80YS) and various power options from 11W to 80W. 

 

 

②Isolated & non-dimmable version

 

LF-GMRxxxYSII, Lifud isolated and non-dimmable linear or tri-proof light LED driver, has 4 models (LF-FMR20/30/60/80YS) and various power options from 8W to 80W. 

 

 

③Non-isolated & dimmable version

 

LF-FSDxxxYA is a Lifud linear non-isolated DALI & PUSH dimmable LED driver which is going to be launched soon. It is equipped with an external resistance connector for self-defined current settings and can be connected to softwares to enable its dimming function (its dimming parameters are no less than self-defined and slow startup ones). Moreover, it has 3 models (LF-FSD037/060/090YA) and various power options from 18W to 90W.  

 

 

PS: LF-FSDxxxYA series is a new product that is going to be launched soon, please contact with Lifud salesmen for more details about its parameters.

 

④Isolated & dimmable version

 

LF-GSDxxxYE is one of the isolated DALI & PUSH tri-proof light LED drivers with full output power options from 4 to 80W on the market. In addition, it has features of 6 models (LF-GSD012/020/030/060/080YE), 0.1% dimming depth, flicker-free effect and smooth dimming effect.

 

 

How to choose non-isolated LED driver and isolated LED driver?

 

If we want to know the differences between them, we are supposed to have a rough understanding on their circuits.

 

In the circuit design of isolated LED driver, the high voltage of LED driver is relatively reduced by the transformer first, and then the LED driver is rectified to output with direct current. And the whole process is the transformation of “electricity-magnetism-electricity”.

 

Isolated circuit design

 

In the circuit design of non-isolated LED driver, the high voltage of LED driver is reduced by inductor, etc. first, and then the LED driver is rectified to output with direct current. And the whole process is the transformation of “electricity-electricity”.

 

Non-isolated circuit design

 

The difference of circuits means that the quantities of used components, cost, efficiency and output parameters are different as well. Please check the following table for the differences between isolated LED driver and non-isolated LED driver with the same output power.    

 

 

When purchasing the non-isolated LED driver, some clients presumably hesitate because of its safety performance. But in general, the tri-proof light is installed at a higher place where our common people cannot reach instead of those professional maintenance personnel. What’s more, the tri-proof light itself is insulated with grounding wire connected, which basically eliminates the potential safety hazards generated by its casing’s exposition to people.

 

In conclusion, the non-isolated LED driver and isolated one are differentiated by the cost, efficiency and specific parameters.  

 

If the cost of the light fixture applied in the lighting project is limited, the non-isolated LED driver can be regarded as a great choice. In this way, the cost of the light fixture can be subsequently reduced, which is beneficial to cut down the expenditures on its operation and maintenance.  

 

If the reliability of the light fixture applied in the lighting project is more important compared with the cost, or the low voltage used in the design of light fixture is necessary, the isolated LED driver is the first choice for the lighting project.

 

That’s all for today.

 

Regardless of Lifud pioneered non-isolated tube light LED driver or its first non-isolated high power LED driver, the safety performance of them has been validated by Lifud 10 years of experience on the design and applications of LED drivers. Therefore, Lifud is professional to drive your puzzles about non-isolated LED driver applications and techniques away.  

 

 

Last but not least, don’t hesitate to choose Lifud LED drivers with fast delivery service!
