Product advantages:
Our centralized power supply is divided into the early conventional constant power output type (a common type in the industry) and the new refined version of unique constant voltage output type, which are for evacuation lighting and indication Marker lamp Provided in case of lack of mains power emergency supply , maintain the system normal. This new generation of centralized power supply is safe voltage 36VDC/DC/constant voltage output type, which has the advantages of longer distance and more lamps than constant power output type.
Advantages of centralized power supply:
1. Unique constant voltage output function (avoiding long distance large line loss and voltage drop defects of power circuit under two-wire system); 2. Power type lithium battery pack is used in the industry (the same type as Tesla: it has over-current self breaking protection function and high safety); 3. Wall mounted design with ultra small volume/weight (saving installation space); 4. Lithium iron phosphate has an average life of more than 6000 charge discharge cycles/12 years or more; 5. BMS intelligent battery management system technology is mature, safe and reliable in the industry. 6. The energy efficiency of the self cooled switching power supply of important components is up to 95% (the rectifier module adopts the international leading PTR soft switch technology), and the durability and service life of the industry are high (self cooled heat dissipation no axial flow fan/less dust accumulation/twice the service life of the industry); Energy saving/environmental protection. 7. High level electrical/electronic component configuration in the industry. (General situation in the same industry: 1. Lead acid battery packs are commonly used/large in size and weight, and short in life. Some manufacturers use lithium battery packs, but: A) only 18650 lithium manganate batteries of the same kind for electric bicycles, with short battery life/no over-current self breaking protection function, and poor safety; B) BMS intelligent battery management system technology is immature/unsafe. 2. The switch power supply of important parts has low energy efficiency (below 88%) and relies on axial flow fan for heat dissipation/large dust accumulation/high failure/short service life. 3. Electrical/electronic components are of low configuration and poor durability. 4. The peers are generally of constant power output type (there is a big defect of long distance voltage drop in the circuit, which is not suitable for places with ultra long circuit paths such as wide areas/long tunnels/urban underground pipe galleries).
