Dual-phase electronic contactors Type ECI-2
General
Type
ECI 30-2
ECI 50-2
Product description
ECI Electronic contactors are designed for applications demanding fast and precise switching.
The contactors utilize SCR power chips with new LTE (Low Thermal Expansion) technology. This unique power
chip design ensures high switching capacity and long life. The contactors are burst fired for reduced EMC emission,
have LED status indicators and accept universal control voltages. The units are DIN-rail mountable, complete with
heat sink and require no additional components.
Typical applications
ECI electronic contactors are designed for fast and demanding switching of loads such as heaters, solenoids,
transformers and motors
