Stanmore, UK The Kilovac EV200 from Tyco Electronics is a small, low-price and hermetically sealed relay with contact ratings of up to 500 A dc. Developed for explosive and harsh environments, the relay is intrinsically safe with no oxidation or contamination of coils or contacts, providing stable contact resistance over years of use, including long periods of non-operation. EV200 relays provide high contact rating for their size for multiple industrial applications, including battery switching and back-up, DC voltage power control, circuit protection and safety applications. A built-in coil economizer requiring only 1.7W hold power at 12 Vdc limits back EMF to zero volts. Coil connection is either via flying leads or optional connectors. An optional auxiliary contact allows for easy monitoring of the power contact position. Mechanical life of the relay is 1 million cycles and it is designed for an operating temperature range from -40 up to +85 °C. The relays are CE marked for EC applications, meet AIAG QS9000 specifications and are recognized to US and Canadian UL File No. E208033. Tyco Electronics Ltd , Stanmore, UK. www.tycoelectronics.com.
