Watlow’s SSR Series of Solid State Selays and Heat Sinks offers many of the advantages of solid state power controls, yet at a lower cost. There are two different versions available: the first rated for applications up to 240VAC; and the second rated for applications up to 480VAC. Both products include back-to-back SCRs for a more rugged design than the traditional triac based solid state relay. The internal design allows it to handle high currents and the harsh electrical environments of heavy industry.

Description
Additional information

Watlow Solid State Relays feature zero cross firing for minimal electrical noise. The fast cycle card on the SSR allows faster switching which gives tighter temperature control for better production and increased heater life. When the internal temperature of the heating element remains constant, it will last alot longer than a heater that experiences continual temperature fluctuations. The total size is just 1-3/4” x 2-1/4”.

Watlow can provide all the components necessary for trouble-free operation. This includes two standard convenience items: a thermal foil to ensure proper thermal transfer from the relay to the heat sink; and belville washers that ensure the relay is mounted with sufficient pressure for good heat transfer. Matched semiconductor fuses and heat sinks are available to complete the power switching package. Agency approvals include UL®, CSA and VDE.
