The difference between UL recognized and UL listed or classified is that it does not apply a seal of approval to end products. ZhenHuan ac dc power supply series is approved UL ETL safety standards.
Any LED drivers marked with“TYPE HL”can be used directly for the end LED Luminaire installed in hazardous(classified) location areas without further evaluation.
PFC (Power factor correction) is a feature included in power supply boxes that reduces the amount of reactive power generated, it mean to improve power factor, and therefore power quality
Pulse width modulation(PWM) dimming for an LED driver involves applying the pulse width modulation mechanism in making a LED driver dimmable. In this post, we can touch some basics about PWM dimming
Due to different circuit designs, there has AC-DC power supply and DC-DC converter when you select. Finding a custom external power supply manufacturer with the required dc output voltage
ZhenHuan AC DC Adapter is a switching mode power adapter that converts 100-240V AC input power into DC output through transformation, rectification, filtering and voltage regulation
CCC certification is a national compulsory product certification, CQC certification is a national voluntary product certification, also known as logo certification, CQC is the abbreviation of China
ZhenHuan ITE power supply series all meet energy efficiency DOE/CEC/ErP/MEPS level VI, energy saving and environmental protection, and reduce the double carbon pressure of 5G application products.
