As a trusted metal oxide varistor manufacturer, TGE is committed to ensuring the reliability and performance of our products. Our rigorous testing protocols, including repetitive charge transferring tests, validate the superior quality and capability of our MOV blocks across various impulse durations and scenarios.
1)repetitive charge transferring test: D28-D42, use lightning inpulse 8/20µs for non EGLA; D46-D115, use 2ms impulse；D33-D38 for EGLA, use 90/200µs impulse.
2)suggested rated voltage is based on center value of U1mA and test according to ICE60099-4.
3)Ures is measured at 5kA for D28-D33, Ures is measured at 10kA for D36-D115.
4)17-19# D42 series are organic coated, others are glass coated.
