Duct Heater Mount Single Channel 50A @ 40°C Ambient
(Burst Fire) SCR Controller, Multi Input, 48-660Vac Line

Anacon Power & Controls SCR Controller's are designed to offer proven solutions to both Phase Angle and Burst Fire applications. Our Burst Fire SCR Controllers operate by varying the duty cycle of an SSR's control input. The power delivered to the load is proportional to the command input signal from four selectable time bases. (200ms, 1 sec, 10 sec & 100 sec.) SCR Controllers allow you to apply more precise control to any heater application, regardless of the type of heater elements you choose.

Notes:

Ratings based upon 100% duty cycle for 20 minutes or 80% duty cycle continuous.
Ratings are based upon relays being mounted either individually or side by side with zero spacing.
Cool One's unique construction allows better performance than conventional heat sink designs even when mounted side by side.
