Product catalog summary
Solid-State Relays Overview
EL.CO. S.r.l. reserves the right to make changes without notice. The document provides detailed specifications for the SM3 series 3-phase solid-state relays, including technical data, selection tables, and wiring diagrams.
Relay Selection Table
The table outlines various models with specifications such as output current (5A), output voltage (20-510VAC), input voltage ranges, and types of commutation (instantaneous or zero crossing). Models include SM31-5480B, SM30-5480B, and others, with options for mechanical auxiliary contacts.
Output Technical Data
Key specifications include a nominal voltage of 480AC, load voltage range of 20-510VAC, and a peak off-state voltage of 1200VAC. The relays have a non-repetitive surge peak current of 120A and an I²t rating of 72A²/S. The output voltage drop is less than 1.5V, with an off-state leakage current of 5mA.
Input Technical Data
Input voltage varies by model, ranging from 15-35VDC to 190-265VAC. Control current and voltage specifications are provided for both DC and AC inputs, with specific pick-up and drop-out voltages.
Input/Output Technical Data
Details include maximum closing and opening delays for both zero crossing and instantaneous commutation, with an isolation voltage of 7500V.
Thermal Data
Operating temperature ranges from -20°C to +80°C, with storage temperatures from -40°C to +100°C.
Wiring Diagram and Derating Curve
The document includes a wiring diagram for connecting the relays and a derating curve illustrating the relationship between temperature and current.
