Watlow Solutions To Common Power Controller Problems

Power controller replacement intervals can be lengthened or problemseliminated by using the optimum power controller for the application. Check thelist below to see if Watlow power controllers can improve your process. Problem Premature heater failureExcessive contactor failureWasted power Unsafe panel wiringEnvironmental concerns aboutmercuryExcessive EMI causingproblems in control circuits Power Control Solution • Stabilize heater element temperature and reduce thermal stress by usinga solid state power control along with a PID temperature controller to reduce the temperature control cycle time• Replace electromechanical contactors with solid state relays. Use E-SAFE
® RELAY for long cycle times, solid state relays for short cycletimes and PID control• Reduce temperature overshoot and power consumption by smoothing outtemperature/heating cycles with solid state power control and PID temperature control• The DIN-A-MITE power controllers, when properly wired are totally safefrom finger and palm electrical shock• Replace with solid state power controller or E-SAFERELAY. The DIN-A-MITE has the same footprint as many MDRs• Correct wire routing for minimum EMI pick-up; change fromelectromechanical and mercury relays, and/or phase-angle fired solidstate devices to zero cross (burst firing) solid state power control
