 Watlow's patent pending E-SAFE® II hybrid power switch provides reliable and accurate power switching up to 35 amperes at 70°C (158°F). Because of the product's unique design, there is no need to purchase costly heat sinks used with traditional solid state relays (SSRs). In addition, this is a three-phase device, so there is no need to wire multiple command signals. With a switching life of millions of cycles and an ambient rating of 70°C (158°F), with no heat sink required, this product is more superior than typical SSRs.
The E-SAFE II hybrid power switch provides operators with longer contact life and higher performance than typical mechanical contactors used in equipment. By using Watlow’s patent pending NO-ARC technology, the E-SAFE II can switch millions of cycles increasing the life of the product with decreased noise and increased temperature accuracy. E-SAFE II's inherent ability to operate at fast cycle time provides a nice complimentary product for a time proportioning (PID) controller.
