Housed in a rugged compact casing, the SDN-P 24-V DIN single-phase rail power supplies are designed for reliable operation in industrial process-control, machine-tool, and other harsh factory floor applications. They meet standards for Class 1, Division 2 hazardous-location networks as well as NEC Class 2 specifications. They're also compatible with DeviceNet specs.
Available with high efficiency levels, they meet SEMI F47 Sag Immunity standards to guard against power-line electrical disturbances. Their power-factor correction reduces power losses. These features are combined in a space-saving high-density package that's just 3.26 in. wide (model SDN 10-24-100P). Other features include an auto-select input of 115/230 V ac at 50/60 Hz, a nominal and adjustable output voltage range of 22.5 V to 285 V dc ±2% (for line, load, and temperature-related changes), and less than 50 mA p-p of ripple current.
Five versions are available: the SDN 2.5-24-100P, SDN 4-24-100P, SDN 5-24-100P, SDN 10-24-100P, and SDN 20-24-100P with respective output currents of 2.5, 4, 5, 10, and 20 A, and respective peak power ratings of 60, 100, 120, 240, and 480 W. All models can be operated in single or in parallel via a front-panel jumper.
Typical efficiency ratings for the five models are 87.5%, 88%, 88%, 88%, and 90%, respectively. The first model can accept 25 A maximum of inrush current, the next two models 20 A maximum of inrush current, and the last models 40 A maximum of inrush current.
SDN-P power-supply prices start at $155 each with availability from stock.
