DIN-A-MITE®
SCR POWER CONTROLLER DELIVERS UP TO 100 AMPERES IN A SMART PACKAGE
The DIN-A-MITE® D silicon controlled rectifier (SCR) power controller provides an inexpensive, versatile product for controlling heat in an efficient package. This SCR controller is designed and manufactured with the quality features expected from Watlow. The back panel mounting matches the footprint of the industry standard mercury displacement relay. There is no need to worry about mercury; the DIN-A-MITE controller is mercury free.
The DIN-A-MITE Style D is capable of zero-cross switching up to 100 amperes single-phase, at 600VAC at 86°F (30°C), depending on the model selected. Two or three controllers used together can control three-phase. It is totally touch-safe and includes standard back panel mounting, on-board semiconductor fuses (accessible from the front) and a current transformer option for external load current monitoring. An optional “shorted SCR detector” feature is available on some models. This model is UL®508 listed and C-UL®and CE certified. These agency approvals are ideal for those panel builders that require agency approvals on their panels and cabinets.
Variable time base, 4-20mA process control, or VAC/VDC input contactor options are available. All configurations are model number dependent and factory selectable. This power controller also includes 200KA short circuit current rating (SCCR) tested up to 480VAC to prevent arch flash with required fusing.

E-SAFE
POWER SWITCHING AT HIGH AMPERAGE AND HIGH AMBIENT TEMPERATURES
The E-SAFE® II hybrid power switch provides reliable and accurate power switching up to 35 amperes at 158°F (70°C). This mercury-free product is specifically designed to operate in the higher ambient temperatures of foodservice applications.
The use of mercury in relays is being eliminated by regulations in the United States and around the world. The E-SAFE II is the best choice for replacing mercury relay switches and 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, since this is a three-phase device, there is no need to wire multiple command signals. With a switching life of millions of cycles and an ambient rating of 158°F (70°C), with no heat sink required, this product is superior to 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 NO-ARC technology, the E-SAFE II can switch millions of cycles to increase the life of the product with reduced noise and increased temperature accuracy. E-SAFE II’s inherent ability to operate at fast cycle times make it an ideal complimentary product for a time, proportional, integral derivative (PID)controller.
E-SAFE II is mercury free, RoHS compliant by design, CE approved and C-UL®/UL® recognized. The reliability of the product is protected by a two-year warranty.

SOLID STATE RELAYS
MORE FOR LESS: LONGER HEATER LIFE AT LOWER COST
Watlow solid state relays (SSR) offer many of the advantages of solid state power controllers, but at a lower cost. Watlow’s extensive knowledge in power controller design led to the development of a special fast cycle input card that enables a solid state relay to operate from a standard 4-20mA instrumentation command signal. Test results show that zero-cross solid state relays in combination with the fast cycle card promote better temperature control and longer heater life than slow cycle relays. Through a time proportional cycle rate of 1⁄10 of a second, heater life will be extended.
Both low and high voltage solid state relays are available from 24 to 660VAC. All ac output models include back-to-back silicon controlled rectifiers (SCRs) for a more rugged design than the traditional triac-based solid state relay. The internal design allows it to tolerate high currents and harsh electrical environments of heavy industry. Watlow also offers a switched VDC model for dc heating applications.
Watlow provides all of 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 belleville washers to ensure that the relay is mounted with sufficient pressure to enable good heat transfer. Matched semiconductor fuses and heat sinks are available to complete the power switching package.
