NOVUS 8824211070 Solid State Relay SSR-4880 80 A / 480 Vac with Heat Sink NDP3-220

Solid State Relays are electronic devices used to switch resistive or inductive loads and have several advantages over standard relays or electromechanical contactors.

Since they have no moving parts, there is no wear or mechanical operating noise. The zero-crossing actuator drastically reduces electrical switching noise. Electrical isolation between input, output, and metal housing simplies and ensures safer installation and maintenance. Properly installed, they can operate without failure for many years.

Features:

• No electrical noise, sparking, or mechanical wear.
• Triggering requires low power.
• LED status indicator of the trigger signal.
• Metal isolated housing.
• Internal dv/dt protection snubber sized to switch resistive or
• inductive loads with power factor up to 0.5.
• Zero Crossing: Turns on at zero Volt, turns off at zero Ampere.
• Optical isolation between command and power.
