LDA24 SERIES |
|
Description:
|
LDA24 series is specifically developed and designed LED power driver design for the LED power supply.
Circuit design adopt non-isolation plan, thereore, the efficiency is up to 95%. Using constant output current and PWM control design, it can maintain the stability of the electric current.
Provided with a wide input voltage from 5V to 36V , a wide output voltage from 2V to 34V, and also there are five standard constant output current for selection, such as 300mA, 350mA, 500mA, 600mA and 700mA.
Output voltage is up to 34Vdc, maximum constant output current is up to 700mA, therefore, it can drive the sum of the largest 23.8 Watts LED particles.
Other standard functions include short circuit protection and over temperature protection. MTBF of up to 2 million hours, ideal for LED indoor and outdoor lighting related applications.
Outer casing is made of DAP material , epoxy potted is also used in line with standard UL94-V0 material, therefore, it is with a good high-temperature features.
RoHS compliant manufacturing process, and every product is 100% gone through the factory burn-in testing to ensure product reliability.
Besides standard products and samples offering, YDS also accept customized services, if you have special requirement, please do not hesitate to contact us, YDS will be serve you in the most professional manner to meet your needs for customized products.
