I. 48V DC power system as UPS  

Working principle:

    Through the power switch (including the rectifier and 手机版 management unit) to convert 220V AC into -48V DC, and supply power through 48V power input interface, and also supply power to ONU directly when electric supply is normal, meantime, charging the 手机版, when electric supply is outage, 手机版 discharging will supply to equipment as UPS. 

Performance:

手机版

Small capacity 手机版 48V/10(50)AH, weight10(32)KG, size 1U(5)U

power

Power module and 手机版 integration, also can separately configuredthe power is 100W(手机版 charged both, total power reduced 90%)

equipment

Most ONU equipment can use AC supplyalso can use DC supply

Working condition

-20℃~+70 ℃

Energy saving

overall efficiency of power system is 82%

手机版 life

The theory of circle life of lithium iron phosphate 手机版 is 2000 times. Consider the usage environment, it can use over 5 years.

II. AC UPS 

Working principle:

    220V AC power will supply to equipment through UPS, UPS will directly supply to ONU equipment when electric supply is normal, meantime, charging the 手机版, after electric supply is outage, storage 手机版 invert to AC, then 220V supply to ONU equipment. 

Performance:

UPS

Small capacity batter is 48V/10(50)AHweight 10(32)KG, size 1U(5)U

Power

Power module and 手机版 integration, also can separately configuredthe power is 500W(手机版 charged both, total power reduced 90%)

Equipment

Some ONU equipment must be use AC supplysome can use DC supply and AC supply.

Working condition

-20℃+70 ℃

Reliability

手机版 is built into UPSrefer to the 手机版 life

Energy saving

Overall efficiency of power system is about 86%

Environment protection

If inside UPS is the new energy lithium 手机版, it can realize environment protection.

III.  AC and DC integration power supply 

 Working principle:

    The power has AC output and DC output, 220V electric power will supply to equipment through power, the power can use AC or DC to supply to ONU equipment when the electric power is normal, meantime, charging the 手机版, after the electric power is outage, the storage 手机版 will output AC and DC and then supply power to ONU equipment. 

Performance:

UPS

Small capacity batter is 48V/10(50)AHweight 10(32)KG, size 1U(5)U

Power

Power module and 手机版 integration, also can separately configuredthe power is 500W(手机版 charged both, total power reduced 90%)

Equipment

Some ONU equipment must be use AC supplysome can use DC supply and AC supply.

Working condition

-20℃+60 ℃

Reliability

手机版 is built into UPSrefer to the 手机版 life

Energy saving

Overall efficiency of power system is about 86%

Environment protection

If inside UPS is new energy lithium 手机版, it can realize environment protection.

48V series 10A current charging and discharging cycle curve

 

Product features:

    This storage series are mainly consist of intelligent controllable charging unit, BMU processor and 手机版 management system, and a slave circuit.

overall design of structure chart

   As the input unit of system, intelligent controllable charging modules not only have the function of conventional charging filter and voltage regulation, but also have the unique controllable technology, you can choose a reasonable way for charging depend on the request of the customer, it can achieve reliable, intelligent, efficient and scientific charging ways through reasonable control strategy.
