Screw type power terminals in a high temperature plastic housing for mechanical ruggedness. Constant Current Input minimizes source current requirement (standard on D input only) Exposed ceramic baseplate for reduced thermal resistance and best thermal performance. Constructed using Teledyne’s unique PowerthermTM process. This process yields superior thermal impedance and power cycling capabilities through reduced thermal interconnections, allowing for cooler, more reliable operation. The logic drive circuitry section uses the latest in reliable surface mount technology.

Where overvoltage transient spikes are present, suppression may be required. An MOV suppressor and/or a snubber circuit across the AC terminals of the module will provide additional transient immunity. 2.) For 400 Hz inductive load, contact factory. 3.)
