Crydom – DIN-rail mounted AC and DC output solid state and motor reversing contactors (DRA)

The expanded DRA Series, from Crydom, now includes compact DIN-Rail mounted three-phase AC solid state contactors, three-phase AC solid state motor reversing contactors, and DC solid state motor reversing contactors.

The expanded DRA complements existing single-channel and four-channel AC and DC output models. The new models offer UL approved AC output ratings of either one or two horse power at 480VAC in both contactor and motor reversing configurations, and UL approved DC output ratings of ¼ horse power at 90 or 180VDC. IEC 60947 ratings are also available for both AC and DC output DRA Series.

DRA Series 3 Phase Contactors feature an SCR output all solid state design with 4000VAC optical isolation, AC or logic compatible DC control inputs, both with input status indicator, UL approved motor and AC output resistive load ratings of either 2.4A or 4.2A per phase from 48 to 510VAC. Motor reversing models also include a control interlock feature that allows only off, forward and reverse operation.

DRA Series DC motor reversing models feature a FET output all solid state design with 2500VAC optical isolation, logic compatible DC control inputs with input status indicator, and UL approved motor and DC output resistive load ratings of either 6A at 180V and 12A at 90V.

Designed for easy mounting to a standard 35mm DIN-rail, the new DRA Series is available with a variety of input and output ratings, says the company
