  Many applications run on  AC DC Adapter . The alternating current(AC) to directing current(DC) adapter that plugs into the wall to run your home printer or electric blanket may be warm to the touch. But If its excessively hot, that usually takes trouble. An AC DC adaptor is a full-sized plastic box that plugs into a household electric outlet. A cable connected to the dc adapter carries safe low-voltage DC. A round barrel power connector at the cable's end plugs into your device. Regulator Inside the AC adapter, a circuit called a regulator keeps the DC voltage steady. Normally, it becomes moderately warm. Overload If your device is working hard, it gets more power from the dc adaptor. The external adapter will get warmer. If overloaded use, it may become hot. Malfunction A problem in the switching adapter's circuits may cause it to run abnormally hot. If it becomes painfully hot to touch, grip it with a dry rag and remove it from the wall outlet. Substitution The voltage, po...

You may wonder what are Class P LED drivers and why should you choose them? The Class P program was created by UL (Underwriters Laboratories) launched in January 2016 with the goal of better supporting luminaire makers by allowing freedom of substitution for LED drivers without having to recertify their products. It`s a program that establishes guidelines for evaluating and testing standardized LED driver constructions and ratings. The Class P program is a UL-listed program. UL listing indicates that UL (Underwriters Laboratories)...

  Dimmers   change the shape of the AC wave by chopping off part of it. This reduces the power available to the LED bulb light, which becomes less bright. The terminology about dimmers can be confusing, such as ELV dimmer, MLV dimmer or Triac dimmer... What does Triac dimmer mean? The key electronic component in a dimmer that makes wave-chopping possible is called a "triac". So all these type of dimmers are "triac dimmers". What`s Leading Edge dimming and Trailing Edge dimming? When chopping a sine wave, you can chop the beginning of the wave, or the end of the wave. In both cases you achieve dimming by reducing the outgoing power. The more you chop, the dimmer the light. So if the triac chops the beginning of the sine wave, it`s "Leading Edge" dimming. And guess what it`s called if you chop the end of the wave? Correct! "Trailing Edge". What`s Forward Phase dimming and Reverse Phase dimming? Forward Phase is another term for Leading Edge dimming...

  The acronym “NEMA” stands for the National Electrical Manufacturers Association. Founded in 1926, the NEMA formed out of the merger of the Associated Manufacturers of Electrical Supplies and the Electrical Powers Club. During that time, electronics had just starting to become prevalent, and industry leaders noted the need for required standards to which electronics manufacturers must all adhere. Not only did NEMA form to monitor the quality and safety of electronics products, but they also wanted create simple processes to ensure compatibility between different devices. The regulation organization also monitors conditions where moisture is an issue, such as times when electronics are outdoors, or if there are other risk factors involved. That NEMA also rates the level of protection against deteriorating factors such as corrosion, gasket aging and construction practices that breach designated environmental conditions. Any facility that works with electronics benefit...

  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. Electrical AC plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world. AC plug is the movable or fixed connector attached to an switching power supply. KSPOWER’s  ac dc adapter  features universal ac input 100-240v, accept various AC plugs for different countries choose.

Class I power units requires an earth wire in the plug and socket, while Class II power units is unearthed and protects the user with double insulation. KSPOWER’s  desktop power adapter  is d...

  Constant voltage power adapter  converts the main power AC 100-240V AC into a smaller usually DC voltage that your end device needs to operate. Usually these are required for charging or powering operated devices. When you purchase, the best way is to check if your device has a specific power adapter already available. If you can not find one then you can find out what your device needs to operate, so inspect the device and look for any labels that indicate either the voltage or mAh/A. Choosing the right power adaptor specs to make sure you check the following: The power supply output voltage matched the rated input voltage of the device. VAC or VDC. The power supply output is greater or equal to the devices rated mAh or A. The plug fits into your device and has the correct polarity. The most common is center positive(+)connectors; also have the less popular center negative(-) connector. Voltage carries the power and the Amps are the measurement of how much power it consumes...

  0/1-10V Dimming Principle 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 Features of 0-10V and 1-10V 0/1-10V dimming driver  is a low voltage analog signal dimming mode, which is controlled by the dimmer changing the voltage of 0-10V to control the led driver’s output current. When the 0/1-10V dimmer is turned up to the maximum, the lamp will output full brightness. When the 0-10V dimmer modulates to 0, the lamp turns off the output. The dimming difference between 0-10V and 1-10V: dimmer and the signal turn-off voltage. When the 0-10V dimmer is set to 0.3V-0.7V, the light is turned off, and when the 1-10V dimmer is set to 1-1.2V, the lamp is turned off. The dimming performance, dimmer distance are related to the number of led drivers and environmental interference. Too many led drivers and too long s...

  What is UL Certification? UL Listed vs UL Recognized? UL is a safety organization that sets industry-wide standards on new products. They continually check these products to ensure they’re up to these standards. UL testing makes sure that wire sizes are correct or devices can handle the amount of current they claim to be able to. They also ensure that products are constructed correctly for the highest safety. The biggest difference between UL recognition and UL certified or classified is that it does not apply a seal of approval to end products. UL Listed: Put simply, Listed products means stand-alone products with a specific function, tested against UL's published and nationally-recognized standards for safety for a specific category of equipment. Products that carry the UL Listed"approval label above mean that the product has been tested by UL to nationally recognized Safety standards and has been found to be free from reasonably foreseeable risk of fire, electric shock an...
