Teledyne Relays in Hawthorne, Calif., is offering the Series DR3P family of power solid-state relays to provide three-phase output to 50 amps to 520 volts AC for applications such as motor control, industrial process control, and heating control. The relays offer AC and DC control with low leakage current. The tight zero-cross window reduces stress on motor loads and keeps electromagnetic interference to a minimum. The relays also provide an integrated heat sink, output transient suppression, and light-emitting diodes that serve as status indicators for diagnostics. These relays are for DIN-rail or panel mounting. Each model measures 3.54 by 3.86 by 4.97 inches and weighs 35.2 ounces. For more information contact the company online at www.teledynerelays.com.
