Series of Class I, Div. 2 rated DIN Rail-mount ac-dc power supplies are available in output voltages from 5 to 48 V. The low power DPP Series is for use in chemical and petrochemical plants, pumping, and distribution stations. The series includes 6 models with Class I, Div. 2, Groups A, B, C, and D ratings; enclosed in rugged insulated cases that are 2.95 x 1.77 x 3.58 in. They are ANSI/ISA12.12 certified.
Each model can operate with ac inputs from 85 to 264 Vac without the need for pre-selecting the ac input range. Each unit will operate from a dc input ranging from 90 to 375 Vdc. The supplies feature a low ripple and noise of 50 mV or less and are protected against over-current and over-voltage conditions. The units meet EN55022 Class B EMI standards (radiated and conducted), are certified to UL/EN60950-1 specifications, and are listed to UL508 and CE Marked.
The units are convection cooled and can operate at full output power over a temperature range from -10‚Â°C to +71‚Â°C, with derating above 60‚Â°C. Typical operating efficiencies reach up to 87%. The units can be mounted on either a TS35/7.5 or TS35/15 standard DIN rail.
