"ZNR" Transient/Surge Absorbers (Type E/J) "ZNR" Transient/Surge Absorbers, For Thyristor Protection Type: Type: E J Type E Type J Recommended Applications "ZNR" Transient /Surge Absorber for thyristors is especially designed to protect SCR power controllers and SCR power sources from high energy transient over voltages. The ZNR is smaller in size and excellent in the clamping voltage characteristics as compared with a conventional selenium surge absorber. The ZNR Type E is for relatively low handling capacity of transformer and Type J is for heavy duty use. Surge protection of SCR power controllers Surge protection of SCR power sources SCR = Silicone Controlled Rectifiers RoHS compliant Note: Ask our factory for Product Specification before use. Minimum Quantity / Packing Unit RoHS compliant Please see Related Information Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
