Littleton, Mass.—XP Power says its DNR family of slimline DIN-rail power supplies for factory automation and industrial process control deliver more power than similarly sized supplies or, alternatively, shrink system size for a given power level. The single-phase AC/DC units, in 25 basic models (total of 70 variations), deliver from 5 to 240 watts at 5 to 48 volts from a universal input. The supplies, which measure as small as 3.48-by-0.89-by-4.53 inches (HWD, 5-18 watt models; 5.59-by-by-3.27-by-4.57 inches for 240 watt models) are also lower in cost than existing products, according to the company.
The DNRs feature a line regulation of ±1 percent or better, load regulation of ±2 percent (±5 percent for 120 and 240 watt units in parallel), and ripple and noise of 100 mV p-p. Efficiency ranges between 84 and 90 percent (at 12 volts, 30-watt models or higher). Output range is adjustable over a wide range; for the 24-volt units, the range is from 21.6 to 30 volts. These units are rated for operation over of -10 to +70°C, with full power up to +60°C. The power supply is also capable of 70 percent of full power at +70°C. MTBF is 200 khours as per MIL-HDBK-217F at +40°C. All units have built in over-voltage and over-load protection.
The 240-watt models come with power factor correction as standard. Options available include spring clip or screw connections to simplify wiring, detachable connectors to reduce MTTR (mean time to repair), and a PFC (power factor correction) option on the 120-watt models.
The DNR supplies are approved to EN60950 for ITE and UL508 for industrial applications. The majority of models up to 60 watts 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.
