Product Description

Product Description

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.
