TM40P277 Surge Suppressor Embedded Protection Power Surge Arrester
TM40P277 is an on-board power supply lightning protection module; it is used for surge protection of
commercial lighting, communication base stations, security, electrical appliances, sockets and other power ports.The lightning protection device adopts full mode protection, adopts UVT technology, and has leakage current and freewheeling interruption function.
The product is small in size and can be soldered on a PCB circuit board for easy installation and application.
The product's maximum discharge current is 40kA and the nominal discharge current is 20kA.
Applications:
* Commercial lighting * Security power supply
* Communication power supply * Industrial power supply
* Precision machine tools * Machine room plug
* Single phase motor * New energy source
* Solar powered * 5G base station
Note:
1. UVT: It is an abbreviation of Ultra low voltage triggering technology. It is a design that absorb the high and low voltage energy of the surge in advance.
It can absorb the surge energy more completely, and the residual voltage is low, and the protection effect on the back-end equipment is obvious. This technology is patented by Ruilongyuan.
2. Leakage current: In this paper, the current flowing through the SPD does not occur when the power is connected. For example, zinc oxide varistor is a device with leakage characteristics.
3. Freewheeling: Current from the connected power source that flows through the SPD during and after the discharge current passes. For example, gas discharge tubes and thyristors are devices with freewheeling characteristics (cited from IEC61643-11).
4. 40kA: Refers to the maximum discharge current (Imax) in the 8/20μs surge waveform test.
5. 20kA: Refers to the nominal discharge current (In) during 8/20μs surge waveform test.
Note:
6. Rated operating voltage: The normal AC mains voltage rating assigned by the manufacturer to the SPD (cited from Ul1449 4th )
7. Max ac voltage range: The maximum AC voltage RMS that can be continuously applied to the SPD.
8. MCOV: the maximum r.m.s. can be continuously applied to the SPD voltage (quoted from UL1449 4th ).
9. Uc: the maximum r.m.s. can be continuously applied to the SPD voltage (quoted from IEC61643-11)
10. Nominal discharge current: The current peak selected by the manufacturer. With SPD, the current waveform is 8/20μs, and the SPD remains
functional after 15 surges (quoted from UL1449 4th ).
11. Max discharge current: The peak value of the SPD current flowing through the 8/20 waveform and the manufacturer's claimed amplitude. Belongs to
the T2 test type (quoted from IEC61643-11).
12. Voltage protection level: The maximum voltage expected to occur between the two ends of the SPD due to the application of a specified gradient of
the surge voltage and the specified amplitude and the inrush current of the waveform (cited from IEC61643-11).
13. Residual voltage (U res ): The highest value of the residual voltage measurement during the pulse of 8/20 μs nominal discharge current. It is an
important parameter of SPD protection capability (quoted from UL1449 4th ).
