Omrdon Technology 
OMP-APX40/380, 40KA, three-phase 380V, AC power supply lightning protection box, dual power supply lightning protection box, subway station/high-speed rail station room UPS dual lightning protection
Products::
Dual power supply lightning surge protection box (Surge Protection Device BOX) is suitable for AC 50Hz/60Hz, 380V and below TN-S, TN-C-S, TT, IT and other power supply system lightning protection, its design basis in line with GB18802.11, IEC61643-11 technical standards, can be two three-phase power supply surge protection, with local audible and visual alarm and remote monitoring and alarm functions, suppressing induced lightning or operational overvoltage generated in the power supply network and information systems electromagnetic induction overvoltage and overcurrent, so that the protected equipment is always in the protection of the system, and the equipment is always in a state of overvoltage. It can simultaneously provide surge protection for two three-phase power supplies, with local sound and light alarm and remote monitoring alarm functions, suppressing the electromagnetic induction overvoltage and overcurrent generated by induced lightning or operational overvoltage in the power supply network and information system, so that the protected equipment is always in a safe and protected state.
Functional Features:
- Maximum withstand 40KA (8/20μs) lightning current impact, action response time less than 25ns
- Real-time monitoring and alarming of common (main) and standby (backup) lightning protection switching/power supply status.
- Real-time monitoring and alarming of the status of the main and standby circuit surge arresters.
- Monitoring of the number of lightning strikes, with the possibility of recording the number of lightning strikes (max. 99, resettable to zero)
- Real-time monitoring of SPD work and degradation status, green light on (power supply work/surge arrester work normally), red light on (SPD failure and accompanied by an audible alarm.
- In the event of SPD failure or damage, the SPD immediately and automatically disengages from the circuit without affecting the original power system and equipment.
typical application::
- Metro Station/High-speed Railway Station Server Room UPS Dual-Link Lightning Protection
- Dual Output Switching Cabinet for Common/Stand-by

Product Dimension Drawing
Installation Notes:
1, the installation must be disconnected from the power supply, is strictly prohibited to operate with electricity.
2, the connecting wire must be multi-stranded copper core wire, wire cross-sectional area must meet the installation requirements. Installation, pay attention to the incoming zero fire wire were connected to the lightning box terminal row of L / N terminals, PE ground line connected to the lightning box PE grounding copper row, can not be connected to the reverse or omission.
3, when the indicator green light, that the power supply and lightning protection is working properly; when red light, it means that the internal lightning protection line failure or has failed, must be promptly investigated and overhauled or replaced.
4, when the remote alarm occurs alarm, said lightning protection box has failed or line problems (and buzzer sound alarm), must be timely maintenance or replacement.
5, lightning counter has a digital display (1-99), that there is a lightning current through; can be reset through the lightning protection box cover panel reset key for zero reset, the counter will be re-counted.
6, lightning protection box without special maintenance, but should be regularly checked whether the wiring is reliable, whether the indicator is normal.
