The most suitable applications for these rugged DIN-rail power supplies are factory automation, light industrial, process control and instrumentation. With single-phase AC input, ratings of 5, 10, 18, 30 and 60 are available. There is a choice of models with output voltages from 5VDC to 48VDC, offering a solution for virtually any industrial application.
A wide output adjustment range is standard on all models. For example the 24V units are adjustable from 21.6 to 28V, depending on the model. An operating temperature range of -10 to +70 degrees C with full power up to 60 degrees C ensures no derating at high temperatures. The power supply is also capable of 70% power at +70 degrees C. Most competitors' models derate at 40 or 50 degrees C.
From the 30W models upwards, the efficiency is between 84 and 90% for 12V or higher voltage models. For monitoring, the 24V models at all power levels above 18W come equipped with a DC-OK relay, and all units feature a DC On indicator. The DNR power supplies are very compact; the 5, 10 and 18W models measuring just 115 deep x 88 high x 23mm wide.
Options available include spring clip or screw connections to simplify wiring, detachable connectors to reduce MTTR (Mean Time To Repair), and all units have built in overvoltage and overload protection.
The DNR supplies are approved to EN60950 for ITE and UL508 for industrial applications. The majority of models up to 60W are also approved to UL1310, making them compliant to NEC Class 2 rating. Additionally, the units meet EN61000-3-2,-3 and Level B performance for conducted emissions.
