SYTH SSR 24-480V Three-Phase Industrial Relay

Three-Phase Electronic Semiconductor Relay (SSR) Series SYTH - Switching Contact

AC output circuit (anti-parallel thyristors), high number of switching cycles (no burning of contact material), noiseless switching, and low trigger power.

• Long life, no moving parts, no contact erosion
• Quiet operation, very advantageous for commercial and medical applications
• Minimal electrical noise due to the option to switch "at zero"
• Easy control and minimal energy consumption for triggering
• Shock and vibration resistant, can be mounted in any position
• Fast switching (approx. 0.1 ms)
• Lightweight
• CE certification

Suitable Applications:

• Heating control
• HVAC, ventilation
• Lighting
• Motor control
• Mobile applications
• Military technology
• Medical technology
• Food industry
• Smart buildings
• Wind and solar energy
