Main function

DXJL2880/127 mining flame-proof and this Ann type lithium ion battery power is big, stable and reliable work, meet the demand of mining equipment to realize uninterrupted power supply. When there are external input ac power supply, the power input dc, ac rectifier for the inverter output AC127V, filter; When the external power supply, the lithium ion battery power supply, to ensure that the output of AC127V uninterrupted.

Main performance

1, the ac input voltage: AC660V \ AC380V \ AC220V \ AC127V, range (25% ~ 15%);

2, ac input voltage frequency: 50 h + / - 5%

3, ac input voltage harmonic: 10%;

4, ac output voltage: AC127V plus or minus 1%

5, the rated output current: 5 a;

6, display: 7 inches LCD screen;

7, the inverter switch time: 0 milliseconds

8, lithium battery power supply time: not less than three hours

9, inverter efficiency: 85% or higher

10 and overload capacity: 105-125%, 5 minutes; 125-150%, 25 seconds

11, ac output voltage harmonic content: linear load acuities were 100% and 3%, 100% 5% or less in nonlinear load

12, UPS has the charging output over-voltage and over-current, short circuit, discharge flow, the protection of high temperature anomalies, and the numerical is adjustable

13, the product conforms to the mine coal apart (and this Ann) requirement of safety technique type lithium ion battery power.

Application environment

Applied to underground capsule, communication equipment power supply, underground lighting etc need mine 127v ac uninterrupted power supply place.

It can be used in the coal mine with explosive gas environment.
