1, good safety performance: normal use without electrolyte leakage, no battery expansion and rupture.
2, discharge performance is good: discharge voltage is stable, the discharge platform is gentle.
3, good shock resistance: the state of the fully charged battery is completely fixed, the amplitude of 4mm, 16.7HZ frequency vibration for 1 hours, no leakage, no cell expansion and rupture, the normal open circuit voltage.
4, good impact resistance: the state of the fully charged battery from 20CM high natural fall to 1CM thick hard wooden boards 3 times, no leakage, no cell expansion and rupture, the normal open circuit voltage.
5, high discharge: 25 degrees Celsius, the state of the fully charged battery constant resistance discharge 3 weeks (resistance only equivalent to the 1CA battery discharge requirements, resistance) recovery capacity is above 75%.
6, charging resistance is good: 25 degrees Celsius, the state of the fully charged battery 0.1CA charge 48 hours, no leakage, no cell expansion and rupture, the open circuit voltage is normal, the capacity to maintain rate at 95%.
7, good resistance to high current: fully charged state of the battery 2CA discharge 5 minutes or 10CA discharge 5 seconds. No conductive part fuse, no appearance deformation
Good safety performance
"Lean liquid electrolyte battery design, are all plates and superfine glass fiber separator without electrolyte adsorption, free flowing inside the battery, no electrolyte leakage under normal use, side installation of 90 degrees can also be normal use.
"Control valve type structure, when the battery is in high pressure occasionally through an automatic, open safety valve, release the pressure, ensure the safety of internally generated combustible and explosive gas gathering, reach explosive concentration, excellent explosion-proof performance.
Maintenance free performance
"Absorption sealed maintenance free use of the cathode gas sealing composite principle, efficiency is more than 95%, under normal circumstances the use of water is few, the battery without regular maintenance infusion.
Green environmental protection
"No mist under normal charging, no pollution, no corrosion of equipment room environment.
Self discharge small
Pb-Ca-Sn alloy with high gas evolution potential was put into the dry environment at 20 degrees for half a year, and it can be put into normal use without power supply.
Applicable environment temperature is wide
"- 45 DEG C can run smoothly.
High resistance to high current performance
"Tight assembly process, the resistance is small, the discharge current discharge can be 3 times the volume of 3 minutes (7 minutes or more than 24Ah to allow continuous discharge to discharge current and discharge termination voltage) or 6 times the capacity of the battery for 5 seconds, without exception.
Long service life
"Because of the high purity of raw materials and long life formula, battery consistency control technology, NP series battery normal float design life of up to 7 to 10 years (more than 38Ah).
Good consistency of battery pack
"Regardless of the cost of the battery group in each cell has the characteristics of relatively consistent, that is put into use after long-term discharge consistency and float consistency, not the individual behind the battery and the battery down.
(1) control the weight and thickness of the grid and the paste quantity from the source;
The general assembly before the plates by weighing and grading (= 38Ah battery), to ensure the consistency of active substances in each monomer amount;
(3) quantitative accurate acid injection, four charging and three discharging system, equalization of battery performance;
Before discharging, the battery is discharged, and the capacity and open circuit voltage are matched once;
The static phase detection over 38Ah battery before departure, after 7 to 15 days of the "test of time", the library again seized 100%, very few can effectively detect line to doubt battery detection;
The library is based on open circuit voltage and internal resistance of battery was two times with the group.
Wide range of power input:
Input voltage with different load range, the maximum can reach 100 ~ 300VAC, great to meet the various types (including voltage fluctuation in remote mountainous areas larger) the needs of users.
Humanized man-machine interface:
UPS has LED and LCD two display interface for users to choose, flexible and convenient.
Sine wave output:
Both the power supply mode and battery mode can output low distortion sine wave power supply, which provides the best power supply for the user's load equipment.
Zero conversion time:
When power cut or complex, UPS switches between power mode and battery mode is no conversion time, effectively guarantee the reliability of load operation.
Input zero line detection function:
In order to avoid the UPS electric power input zero fire line reverse connection, the UPS specially designed the anti - echo alarm function. Bypass output humanization:
UPS can set the bypass working range through software.
The TVSS (TRANSIENTVOLTAGESURGESUPPRESS voltage surge) protection function is added to the input terminal to prevent transient spikes and surge surges.
Input power factor correction:
The series of UPS input power factor correction function, input power factor can reach above 0.99, the grid user environment will not be polluted, is the real environmental UPS.
In the absence of power supply, UPS can start backup directly with backup battery, so as to meet the emergency needs of users.
The protection range of bypass voltage can be set by software to avoid load damage due to excessive bypass voltage when the inverter is switched to bypass.
Auto start function:
When the utility power is abnormal, UPS into the battery powered mode until the deadline, UPS will shutdown, when electricity is restored, UPS will automatically start, the user need not one boot.
Long term power supply design:
In order to meet the needs of different users, UPS provides a long delay charging circuit for the user to choose, the longest time up to 12 hours.
Long acting machine powerful charging capacity:
In addition to the prolonged discharge time, the UPS long acting machine has a very strong recharge capability, and can provide an initial charging current of about 7 to 8A.
Results of self check function:
In the boot, UPS to simulate the power outage, battery power and other abnormal situation self-test, can also be normal operation, press the front panel button self-test, but also through the monitoring software to set the timing cycle detection.
According to the electromagnetic interference and radio frequency interference, according to UPS international standard EN500912 and IEC61000-4 series standard design, effectively improve the safety and reliability of using UPS.
It can be used with generators:
Wide input voltage and frequency range, so that UPS can be used with a series of brand generators, longer use time, and effectively remove the bad power generated by the generator, providing a clean, safe, stable power supply for the load.
