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.

  1. Rated operating voltage: The normal AC mains voltage rating assigned by the manufacturer to the SPD (cited from Ul14494th)
  2. Max ac voltage range: The maximum AC voltage RMS that can be continuously applied to the SPD.
  3. Mcov: the maximum r.m.s. can be continuously applied to the SPD voltage (quoted from UL14494th).
  4. Uc: the maximum r.m.s. can be continuously applied to the SPD voltage (quoted from IEC61643-11)
  5. 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 UL14494th).
  6. 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).
  7. 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).

About UVT

Since the introduction of the 20kV ultra-thin surge suppressor in 2014, Ruilongyuan Electronics has continuously improved its surge protection technology technology and proposed the theoretical concept of efficient absorption of surge energy. After many tests, the circuit model was established and the ultra-low voltage triggering scheme (UVT1) was introduced. It was applied to the new totem surge suppressor, which greatly improved the surge protection efficiency and played a good role in the protected equipment. Surge protection effect.
