Products
OMRDON T1 single-phase / three-phase lightning surge protection box (Surge Protection Device BOX) for AC 50Hz/60Hz, 380V and below, TN-S, TN-C-S, TT, IT and other power supply system lightning protection, for LPZ0A or LPZB zone and LPZ1 zone junction, the design of the According to GB18802.11, IEC61643-11 technical standards. Built-in spark gap lightning protection module, the outer panel of the box has a digital lightning recorder, recording the number of lightning wave impact and date, with power-down memory function; and the correctness of wiring and work status, fault indication, easy to query and observe.
Functional Features:
- Large throughput, low residual voltage; can withstand up to 25KA (10/350μs) lightning current impact, action response time is less than 100ns.
- T1 level lightning impact protection with overheating protection.
- With lightning strike recorder, accurately record the number of lightning strikes and the time of lightning strikes (accurate to the year, month, day, hour, minute and second).
- The visual indicator color indicates the working status of the protection, green (normal), red (fault).
- With telecommunication function, remote monitoring can be realized.
typical application::
- Main switchboard wiring
- Distribution box at the junction of Zone LPZB and Zone LPZ1
Lightning strike recorder commissioning instructions:
1. Records search
In the dormant state, randomly press the ”function” key once to wake up, two characters in the lower left corner of the display, ”y” when it means ”year, month and day”, ”H” when it means ”hours, minutes and seconds”. When ”y” means ”year, month and day”, ”H” means ”hour, minute and second”. A lightning strike record is displayed in two frames, the first frame displays ”number of lightning strikes“ and ”year, month and day”, which is displayed for 5 seconds; the second frame displays "number of lightning strikes" and "hours, minutes and seconds"; the second frame displays "number of lightning strikes" and "hours, minutes and seconds". The second frame displays "number of lightning strikes" and "hours, minutes and seconds" for 5 seconds, cycling through the display twice. Before dormant, press "down-" key to turn page forward, press "up+" key to query backward, no operation within 20 seconds, enter dormant state. If the number of lightning strikes is 0, there is no date and time display.
2. Clock calibration
In hibernation state, press the ”school time” key screen is awakened, the lower left corner of the screen ”y” is the ”year, month and day”, and the ”year” number is flashing; you can use the ”up +” or ”down -“ key to enter the screen, the "year" number is flashing; you can use the "up +" or "down -" key to enter the screen. The number of "year" is flashing; you can press "up+" or "down-" key to enter the "year".
Press the ”Calibrate” key to correct the ”Day of the month”. Press ”Calibrate Time” key to calibrate ”month and day”. After that, press the ”Calibration” key again, it will go to the second frame to calibrate the "hours, minutes and seconds", after the calibration is completed, press the "Calibration" key again, it means that the calibration is completed.
3. Counting Zero
Lightning strike recorder can store 5000 records, when the record is almost full to zero the recorder, or to set a new record start time, also need to record the recorder ”zero” operation. In the dormant state, press the “zero” key, in order to avoid misuse, the first time you press the “zero” key for three seconds, and then the second time you press and hold down the “zero” key for two seconds after the validity.” After "Zero" is pressed, the lightning strike record is no longer found, and the lightning strike count is displayed as 0.

Installation Precautions
1, the installation must be disconnected from the power supply, is strictly prohibited to operate with electricity. Connecting wire must be multi-stranded copper core wire, wire cross-section area must be in line with the project installation requirements.
2, when the red indicator light or remote alarm alarm (elected to be equipped with telecommunication function), that the lightning protection box has failed or the line out of the problem, must be promptly repaired or replaced.
3、This lightning protection box does not require special maintenance, but should be regularly checked whether the wiring is reliable, indicating whether the window is normal.
