AC power cord plugs and sockets connect electric equipment to the alternating current (AC) mains electricity DC power supply in buildings and at other sites.
The dimmable driver is designed with a control chip, when a 0-10V or 1-10V dimmer is connected, the output current of the led driver can be changed through the 0/1-10V voltage change.
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
