NOVUS SSR line is certified by Underwriters Laboratories

Within NOVUS’ range of products for Process Control and Indication, the Solid State Relay (SSR) line has just been certified by Underwriters Laboratories (UL). The seal proves the safety and guarantee of electronic devices. In addition, it has international recognition.

SSRs are used to switch resistive or inductive loads and have numerous advantages over the more conventional electromechanical relays. A command signal (INPUT) determines the load activation through the output terminals (OUTPUT).

With a lifespan of millions of operations, high speed, no electrical noise or sparking, no mechanical wear, and the need for low power to be triggered, Solid-State Relays are perfect for processes that need control and high precision.

About UL Certification

A global leader in safety science, UL provides a certification that ensures that electronic products meet a certain standard of safety, quality, and performance. This certification serves to add confidence to certified products after product inspection and testing processes.

Widely accepted in the global market, this seal is a requirement for using these products in countries such as the United States and Canada, among others.


NOVUS SSRs that have the recently issued UL certification are already consolidated equipment in the market. See below the details of each of the certified SSRs and a video of how to install an SSR in a controller.


Installing an SSR in N1200

SSR – Solid State Relay 10 to 100 Amperes

It has a lifespan of millions of operations. This SSR operates at high speed, produces no electrical noise or sparks, and suffers no mechanical wear. The triggering requires low power. Perfect for operations where high-precision control is critical.


SSR – Solid State Relay 150 to 300 Amperes

Solid State Relay for high currents. It is also suitable for switching several loads. Electric pulse control from 4 to 32 V. Load voltage of 480 Vac and dv/dt of 300 V/us.


 SSR – Solid State Relay 40 to 90 Amperes (3-phase)

Upon receiving a command signal at its input terminals, SSR turns on and supplies power to the load. This will happen the next time the mains voltage passes zero.

When switching off the equipment, this process will also happen. The command signal is removed, but SSR only switches off when it next passes zero. This means that the delays will never be more than 8.3 milliseconds between the instant the ON/OFF command is triggered and the process of feeding the load.
