Summary



1.1 Products Characteristics KELONG® DJN1000-S inverter powers of sine wave for communication accord with ISO IEC146-4, GB7260, maintenance regulations of MINPTT, certification and examination details of network admittance quality of the inverter equipment for communication, and can be inverter power supplies in the environments such as post telephone and telegraph, railway, marine etc. and AC uninterrupted power supplies for that such as Chinese teletex facility, telegraph terminals, wireless call facility, data switching exchange, local exchange, microwave communication facility, charging system for the cell type exchange, facsimile apparatus for character and image, kinds of AC instruments and computers etc. DJN1000-S inverter powers, being able to supply high-performance uninterrupted AC power for various precision instruments, have mainly the following characteristics and functions: 



Adopting rack imbed design so as to be more slinky and tide.







Guard of input polarity opposition −







Normal startup −







Issue 04 (2013-09-12)



The inverter will send out alarm noise every 0.5 seconds but continue normal power supply to loads as the input voltage above the over-voltage alarm point. When the DC input voltage is higher than the over-voltage protection point, the inverter will shut down automatically for protection with no output.



Communication −







The inverter will send out alarm noises every 0.5 seconds but continue normal power supply to loads as the DC voltage below the low-voltage alarm point. When the DC input voltage is lower than the low-voltage protection point, the inverter will stop inversion, sending out long alarm noise and highlight the BATH/L indicator on the panel, so as to avoid the damage to the DC power resulting from low-DC-voltage.



Over-voltage alarm and protection for DC input −







The inverter will supply normal voltage in 5s–20s after the on/off key on the panel pressed if the DC input voltage is in the required range for the normal startup.



Low-voltage alarm and protection for DC input −







When DC input polarity terminals reversely connected, the inverter would not work but not be destroyed.



The inverter offers dry connector. Through the dry connector, the work status can be monitored.



Self-startup when input voltage resumes to normal

1 Summary −







Over-voltage protection for output −







The inverter will stop inversion and send out continuous sound-light alarm if the load undergoes short circuit. Restart the inverter manually once the trouble is eliminated.



Bypass auto-lock −







The inverter will stop inversion and turn to bypass output, sending out sound-light alarm as overload for period of time. Once the load resume to normal, the inverter will turn to inversion output automatically. The overload protection drop is about 10%.



Short circuit protection for AC output −







When the temperature of the main radiator goes beyond the over-temperature protection point the inverter will stop inversion and turn to bypass output, sending sound-light alarm. The temperature drop is about 20°C.



Overload protection −







The inverter will stop inversion and turn to bypass output, sending out sound-light alarm as the output voltage below the low-voltage protection point. Restart manually the inverter once the trouble is eliminated.



Over-temperature protection −







The inverter will stop inversion and turn to bypass output, sending out sound-light alarm as the output voltage above the over-voltage protection point. Restart manually the inverter once the trouble is eliminated.



Low-voltage protection for output −







The DC input voltage out of normal startup range will results in self-shutdown of the inverter, bypass output and sound-light alarm. When the voltage recovers, the inverter will restart automatically.



To avoid frequent conversion, the inverter will be auto-locked to bypass output with continuous sound-light alarm when the inverter switches to bypass output 3 times continuously in 5 minutes. Restart manually the inverter once the trouble is eliminated.



AC input abnormal status alarm −



If Li, Ni reversely connected, the buzzer will alarm intermittently.
