AC Input Voltage – The nominal range on the power supply label as approved by the safety agency is always 10% less than the usable input voltage range. For example, a switching power supply with a nominal 100 to 240VAC has an actual range of 90 to 264VAC. Our datasheet shows the usable voltage range; the label […]

The basic factors to consider when choosing an LED driver. 3. How to purchase a suitable LED driver on MOONS’ official website with your requirements.Unlike the industrial switching power supply, LED […]

1.1 What is Power Factor? Power factor (pf) is defined as the ratio of the real power (P) to apparent power (S), or the cosine (for pure sine wave for both current and voltage) that represents the phase angle between the current and voltage waveforms (see Figure 1). The power factor can vary between 0 […]

1. DALI History Digital Addressable Lighting Interface (DALI) is a protocol for digital lighting control that enables the easy installation of robust, scalable and flexible lighting networks. Today DALI is the most common used digital protocol for light. And DALI protocol is maintained by Digital Illumination Interface Alliance (DiiA), a global consortium of lighting companies […]
