FEATURES/BENEFITS * Three-phase solid-state relay in a compact SIP package * High-temperature plastic housing for mechanical ruggedness * Tight zero-cross window for low EMI * Exposed ceramic baseplate for reduced thermal resistance DESCRIPTION The Series C3P three-phase AC solid-state relays are designed to control medium amounts of power in three-phase applications. Optical isolation ensures complete protection of the C3P's control circuit from load transients. The C3P's compact plastic housing provides a low-cost alternative to large metallic threephase contactors. The C3P is designed with heatsinking in mind. The ceramic baseplate provides excellent thermal performance. The relay's tight zerocross window greatly reduces EMI. APPLICATIONS * Heating control * HVAC controls * Light/Lamp control * Three-phase AC loads
