34S MOV

1.34S metal oxide varistor (MOV), with epoxy resin
2. Diameter and thickness is controlell effectively within the design scale.
3.Peak current is reached the world leading level. It can afford 8/20us impulse, peak current Imax 40kA punch 2 times.
4.Thermal stability. Soldering thermal cutoff member with 145 degree, the cutoff time is no less than 5 senconds under 1A current; the cutoff time is 3-5 seconds under 1.5A current.
5.Energy absorption capacity, applied 2ms impulse, impulse current is 600A, the max. energy absorption capacity is more than 1000J.
6.Life time. Applied 83% varistor voltage at 85 degree to accelerate aging. The lifetime characteristic curve is good, varistor voltage change rate is less than +/-10%
7.power frequency withstand. Applied 1.2 tims electric load rate, tested for 5 minutes, the varistor is good, the varistor voltage change rate is less than +/-10%.
8.Stability. To exposure in the air for one week, varistor voltage and leakage current is less than |+/- 10%, product performance stable.
