Hybrid Power Switch Offers Power Switching at High Amperages and High Ambient Temperatures
Watlow’s patent pending E-SAFE II hybrid power switch provides reliable and accurate power switching for the foodservice industry. The E-SAFE II is fully RoHS compliant by design and mercury-free. It offers a switching life of millions of cycles at 35A at a high ambient temperature rating of 70°C (158°F) in applications such as conveyor and convection ovens, grills and fryers. The inherent fast cycle time provides a complimentary product for time proportioning PID controllers. Patent-pending NO-ARC technology allows it to switch millions of cycles while decreasing noise and increasing temperature accuracy. The switching mechanism of Watlow’s E-SAFE II is a hybrid solid state and mechanical relay. This allows faster cycling and more precise control, which helps contribute to energy savings and extend heater life. In addition, E-SAFE II does not require the use of heat sinks.
