High-speed switching pulsed laser diode driver
Industry type:Electronics and communication
Product model number:LDPC-50A Series
award 3

LDPC-50A is a high-performance laser diode driver that is capable of high-speed pulsed switching, fast response time, low ripple current, high efficiency, and intelligent control functions. The R&D team designed with a patent-worthy hysteresis current control topology in order to achieve an ultra-fast current pulse rise and fall time of < 2?s. The fast response time not only significantly reduces the processing time, but it also improves the material processing quality.

Other outstanding features such as 5kHz high-speed current pulsed switching, low ripple current < 1Arms, and low overshoot < 5% enable high precision laser processing of a small area as well as smooth and even processing of a large area. When used in a laser system for cutting multi-layered materials, the LDPC-50A may be controlled by an external signal to modulate the output current between 0A to 50A, which significantly improves the production efficiency by providing the optimal power level for different materials.


Established in 1982, MEAN WELL is a leading branded standard switching power supply manufacturer. With 34 years of history, MEAN WELL is characterized by a wide product range, flexible production ability and building safe products. Right now, more than 5,000 standard models have been sold through over 200 distributors to 80 countries under our own brand name. Product applications include automation, IT, moving signs, LED lighting, electronic displays, and telecoms.


In 1982, MEAN WELL’s founder, Mr. Jerry Lin established MEAN WELL enterprise to produce Apple, IBM compatible switching power supply as main products. The original brand name "MEAN WELL" was derived from his English dictionary. MEAN WELL means "have good intentions".

This meaning is consistent with Mr. Lin’s personal belief - one who has right thinking, good intention and runs a legitimate business, no matter he is capable of accomplishing a noble goal or not, he should persist and conquer. Later on, from the similar English pronunciation of “MEAN WELL”, it further came up with 「明緯」as the Chinese company name.

In 1986, Taiwan’s OEM/ODM orders for electronic industry were booming, however, MEAN WELL gradually abandoned this business model and decided to cultivate our own brand. We started to develop standard switching power supplies and paid much more attention on quality and reliability. ”MEAN WELL means Quality Switching Power Supply”, this slogan is actually the extension of the original of the enterprise. We provide the best quality of power supplies based on the belief of sincerity, so that our clients feel reliable about the brand “MEAN WELL”. MEAN WELL represents “The Mark of Reliability”.
