Applications:
The EC7AW and EC2SBW-H series are perfect for detectors, sensor equipment, vehicles, airborne systems, communication systems, and industrial applications that require:
●Metal case with plastic base: Features good EMC performance and high temperature power de-rating.
●Compliance with EMI standards like EN 55032 Class A (Without External Component) and EN 55032 Class B (Simple External Component).
●3000Vdc(2000Vac): High I/O isolation voltage, provide safer isolation protection for end devices and systems.
●All have remote on/off functions, making system control more convenient and faster.
●Operation in harsh conditions with reliable performance such as operating case temperature range of -40 to +105°C and EC2SBW-H Series offers models for -55°C operation (Suffix “-M2”).
The EC7AW and EC2SBW-H series are versatile, high-performance DC-DC converters designed for demanding applications. With robust metal casing, high EMC performance, and compliance with EN 55032 standards, they ensure reliable operation in harsh environments. Achieving EMI compliance is effortless—Class A requires no external components, while Class B only needs a few extra components. Featuring 3000Vdc isolation, remote on/off control, and wide operating temperature ranges, these modules provide enhanced safety, efficiency, and ease of integration for various industrial and mission-critical systems.
