IEC EN 61558 standard for Transformers and Power Supplies October 28, 2024
Among the many international technical standards aimed at ensuring product quality and safety, IEC 61558 is important to engineers working with any equipment that contains a transformer or power supply.
The Difference Between Type TL and Class P LED Driver October 28, 2024
Due to the flexibility of UL's component certification program, the structural design of LED drivers is variable, resulting in various testing methods. This flexibility also means that in most cases any two LED drivers cannot be interchanged without additional safety evaluation. Against this background, UL has successively proposed the "Temperature Limiting LED Driver Certification Program (Type TL LED Driver Program)" and the "Overheat Protection LED Driver Certification Program (Class P LED Driver Program)".
- 240 watt led driver
- 24v dc class 2 power supply
- 36v led power supplies

KSPOWER POWER SUPPLY SAFETY MARKS AND AGENCIES~ October 28, 2024
The previous section identified many of the national and international bodies that either define regulatory requirements for product safety or provide testing and certification to assure users that the device or equipment complies with the relevant standard(s). Consequently, conformance marking of products to show this compliance is a necessary prerequisite for their sale in most industrialized countries and may be a legal or contractual obligation.
- Alternative Adaptor
- Inverter AC to DC
- Solar Inverter 12 Volt
KSPOWER POWER SUPPLY SAFETY STANDARDS~ October 28, 2024
The ability to sell external power supplies or led drivers types, around the world depends on meeting the relevant safety standards that apply in those territories. These standards are defined and
The Basics of AC DC Power Adapter Surge Protection October 28, 2024
Lightning strikes are a common source of external surge transients and carry far more current at far higher voltages than most electronic systems are rated for. These voltage surges are typically large enough to cause the immediate failure of electronic devices if the appropriate level of protection has not been applied.
What LED Drivers NEMA and IP rating October 28, 2024
Reputable manufacturers of power devices like LED drivers and transformers prioritize safety and longevity in the design phase because low voltage does not necessarily mean low risk. Safety classifications such as UL, Class 2 and Class P (discussed in our previous blog) are important to consider, but what about enclosure ratings for lighting systems installed in outdoor settings?
