Watlow solid state power switching devices complement the rapid switching required by PID temperature controllers and help deliver optimum system performance and service life. They are available in 1-phase and 3-phase/2-leg and 3-leg configurations, feature touch-safe terminations, input indicators, zero-cross, random or phase-angle fire options, ratings from 18 to 1,000 amperes and agency approvals including CE and UL® 508. Various configurations offer short circuit current ratings (SCCR) of 200,000 amperes, extensive system and heater diagnostic capabilities, heater bake out, integrated heat sinks, on-board fuses, RoHS compliance and serial communications.

The Watlow DIN-A-MITE® B is a low-cost, highly compact and versatile solid state electric heat controller. The DIN-A-MITE B capabilities include single-phase and three-phase zero-cross switching up to 40 and 22 amperes, respectively at 600VAC (see rating curve). This electric heat controller's design includes proper heat sinking and terminations simplifying integration into applications. DIN-rail and back panel mounting is standard on this electric heat controller. The Watlow DIN-A-MITE controller is also mercury free.

Variable time base, 4-20mA process control or VAC/VDC input contactor versions are available. A shorted silicon controlled rectifier (SCR) alarm option is also available. All configurations are model number dependent and factory selectable. This power controller also includes 200KA short circuit current rating (SCCR) tested up to480VAC to prevent arch flash with required fusing.

Features include single-phase and three-phase zero cross switching up to 40 and 22 amperes, respectively, at 600VAC (see rating curve). A unique, integrated design removes the guesswork associated with selecting a proper heat sink and adequate terminations for the application.

Watlow Limit and Scanner Controllers

Anderson-Bolds Provides High Quality Watlow Temperature Control Products

Watlow LIMITS AND SCANNERS

Watlow single and multi-loop limits provide cost-effective solutions for single- and multi-channel, temperature monitoring. Limits monitor the process value where thermal system protection is needed, closing a contact output for normal operation and opening that contact to shut down the process or equipment when the value is outside the safe range.

Various configurations offer user-selectable or fixed-configuration sensor options including thermocouple, process, RTD and thermal switch inputs as well as user-settable or fixed limit values. Models with displays have user-selectable temperature units. Other features include sensor break protection, industry standard I/O options and UL® and CSA approval. All limits and scanners are RoHS compliant. Limits have FM approval for performance in limit (Over Temperature) applications. Watlow limits are designed and manufactured to withstand harsh industrial environments and come with a three-year warranty.
