An emergency conversion kit is also known as an emergency power unit or emergency power pack. It consists of an inverter and a rechargeable battery pack. When AC power is present, the inverter keeps the battery charged and in standby mode. When AC power is interrupted, the inverter automatically converts the DC battery power to standard AC voltage, providing backup power for the luminaire. to ensure its use as a safety and emergency luminaire. It provides 1-3 hours of emergency lighting with battery packs of different capacities. The technical characteristics of the  emergency conversion kits  vary according to the emergency lighting requirements.     For LED, fluorescent or halogen lamps Different light sources require different inverter circuits. Even if they are both LED conversion kits, the kits for use with LED bulbs/tubes (with integrated drivers) are different from the kits for LED panel lights/downlights (with separate drivers).   Maintenance or non-maintenance. Two modes of em

The phenomenon of "hard to find a cabin" has become more obvious recently, especially some time ago, with the outbreak of a large-scale new crown epidemic in India, flights from Guangzhou to Shenzhen must basically be booked a week in advance. Sea freight is soaring, it is hard to find a container, and it is hard to find a cabin by air! According to Flexport's analysis, The current floating average spot market rate from Asia to the West Coast of the United States is basically an average of US$10,000. plus equipment surcharges of US$3,000 to US$9,000 and priority loading fees, the actual shipping cost for moving a cabinet is US$13,000 to US$19,000, which is 10 times higher than before the epidemic. From Asia to the East Coast of the United States, including a surcharge of US$2,000, the actual shipping cost is between US$16,000 and US$21,000. The actual shipping cost from Asia to Northern Europe is between 15,000 and 20,000 US dollars. To help you along the way, here are so

In the past, nickel cadmium batteries, nickel hydrogen batteries and lead-acid batteries were widely used in fire emergency lamps. However, nickel cadmium batteries and lead-acid batteries contain cadmium and lead respectively. At the same time, the specific energy of these two types of batteries is low and the volume is relatively large; The Ni-MH battery fully considers that the hydrogen absorbing metal alloy powder of the negative electrode is not conducive to long-term floating charge, the price is relatively expensive and the volume is relatively large.  Therefore, more and more manufacturers begin to use lithium batteries in the product of fire emergency lamps. Among them, cylindrical lithium-ion batteries made of ternary and lithium iron phosphate are more used. However, there are great differences in price and safety performance between ternary battery and lithium iron phosphate battery. The price of ternary battery is cheaper than lithium iron phosphate battery, but the safety
