Watlow Electric E-Safe II - Manual

E-SAFE ® II Provides
Power Switching at
High Amperage and
High Ambient
Temperatures
The patent pending E-SAFE ® II hybrid power switch from
Watlow ® provides reliable and accurate power switching up
to 35 amperes at 70°C (158°F). This mercury-free product is
specifically designed to operate in the higher ambient
temperatures of foodservice applications.
The use of mercury relays is being eliminated due to many
regulations affecting its use in the United States and around
the world. When replacing mercury-relay switches, the E-SAFE
II is the best performing product at the most economical price.
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 foodservice
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.
Not only are you faced with mercury phase outs in order to
compete in the international market, you must consider RoHS
compliancy. E-SAFE II, while being mercury free, is also RoHS
compliant by design, CE approved and C-UL
® /UL ® recognized.
The reliability of the product is protected by a 24 month
warranty.
