Lance engineers & consultants offers watlow [usa] din-a-mite style-d scr power controllers, which are inexpensive, versatile products for controlling heat in an efficient package. Watlow products are designed and manufactured to high quality standards. The standard back panel-mounting footprint is equal to that of an industry standard mercury displacement relay. There is no need to worry about mercury; the din-a-mite controllers are mercury-free. They are capable of zero cross switching up to 100 a single phase, at 600 v ac at 30ºc [86ºf] depending on the model selected. Gaging the inputs of two or three controllers enable control of three- phase supply. 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. Agency approvals like ul 508, c-ul and ce are ideal for those panel builders that require agency approvals on their panels and cabinets. Variable time base, 4 to 20 ma process control, or v ac/dc input contactor options are available.
