The Back-up Power
Back-up power is a kind of auto-driving of power that can be effective to prevent driving circuit without the normal voltage, and it can be extended to the voltage circuit to make sure that the circuit can work normally. Back-up power is also called a battery backup, power supply. The power can be used in diiferent areas and applications and there are also many batteries made of different materials. Now we will introduce you two main kinds of the back-up power as following.
The Specification of Vrla Battery
The meaning of vrla battery is the battery which is designed in valve regulated lead acid. Its specification includes: front accessible terminals, gas recombination, manifolded gasing system, spill-proof and leak-proof, reliable one-way safety valve, flame retardant cases optional, flame-arresting one-way pressure-relief vent for safety and long life, inimizes battery interconnection cost and resistance with supplied copper connectors, thermally welded case-to-cover bond to ensure a leak-proof seal, thick positive plate design for maximum service float life, and UL-recognized component.vrla battery never needs watering and it operates at a low internal pressure in low self discharge rate. Flame-retardant polypropylene case and cover compliant with UL94 V-0 with an Oxygen Limiting Index of greater than 28. Solid Gel technology for efficient gas recombination 99% plus. Front accessible threaded copper alloy terminals for ease of assembly and reduced maintenance. And it also complies with UL1778, 924, 1989 and 94 V-0. It can be used in any orientation. Upright, side or end mounting recommended with multicell design for ease of installation and maintenance. As it complies with IATA/ICAO Special Provision A67 it will not restricted for air transport. As it classified as non-hazardous material as related to DOT-CFR Title 49 parts 171-189, it will not be restricted for surface transport. As it classified as non-hazardous material per IMDG Amendment 27 it will not be restricted for water transport. Battery design allows for 48VDC configuration in a standard 23" relay rack.
The Specification of Opzv Battery
The positive electrode of Opzv battery is AGM Plate with antiminy-free special alloy. And opzv battery's negative electrode is flat grid plate with its electrolyte: suspended thixotropic gel, container & cover sAN optional V-0 and its separator is microporous plastic with float Voltage 2.23 VPC +/- 1% at 20 C Max. Charge Voltage: 2.40 VPC at 20 C. Its safety valve is 1-3 PSI self-resealings and its terminals are integral copper insert with insulated cables interconnects.
