Product Name: Rh7-900-75 Hot Cathode UV Lamp Electronic Ballast Model NO.: RH7-900-75 Voltage: 110-240V Certification: CE Resistant: Shock-resistant Start Mode: Preheat Usage: UV Lamp Transport Package: Suit for Air Transport Specification: 185*56*45 mm Origin: China HS Code: 8504109000 Product Description Ningbo Sunfine Environmental Technology Co., Ltd. provides various electronic ballasts for different UV sterilization lamps. The performance of the device depends on the matching between the lamp and ballast, so it is necessary to choose the right electronic ballast. As an electronic circuit component, germicidal lamp is considered to be an active molecule, because it will produce harmonic and transient voltage and current. They have a characteristic that the voltage decreases with the increase of current, which is called negative current resistance. Therefore, the germicidal lamp is inherently unstable. once ignited, there is no limit. A ballast must be used to restore and maintain the working current. Our company has established the design and test system of ballast and lamp matching to provide the best matching for customers.RH7-900-75 Preheat Electronic Ballast For hot cathode uv lamp detail:ModelInput VoltLamp WattStart wayOutput CurrentRH7-900-75110~240V60~100WPreheat0.85APacking Photo :
