Crydom – New panel-mounted high-current DC load solid-state contactors (DP4R60D20)

With optional soft-start, soft-stop and brake features, for use in DC load reversing applications up to 60A at 48VDC, Crydom’s advanced DC switching technology is now conveniently packaged in a high-power ‘H’ bridge configuration.

The DP Series high-power ‘H’ bridge configuration DC output solid-state contactors are rated for general use at 20A, 40A or 60A, and motor-controller rated for 15 FLA from 1 to 48VDC in a 40C ambient temperature. The DP Series accepts logic supply and input controls of either 4.5 to 15VDC or 18 to 32VDC.

Optional soft-start / soft-stop functions utilizing internal PWM are available with 0.2, 0.5 or one second ramps. An optional brake function (not available with soft-stop) is available with 0.2, 0.5, 0.8 seconds or continuous hold.

The DP Series are of an all-solid-state design with 2.5Kv optical isolation and incorporate low dissipation power FETs for fast and efficient load control and are housed in an industry standard 75mm x 105mm panel-mount package. Power and load terminations are via screw terminal post, while input control is through an industry-standard four-conductor connector. The devices are CE certified, RoHS compliant, UL/cUL recognized for both general-purpose and motor-controller applications, says the company.
