Lambda's DPP series includes 6 models with Class I, Div. 2, Groups A, B, C and D ratings; enclosed in rugged insulated cases that are only 2.95" H x 1.77" W x 3.58" D. These ANSI/ISA12.12 certified supplies include the following models (volts/amps): DPP25-5 (5V/5A), DPP30-12 (12V/2.5A), DPP50-15 (15V/3.4A), DPP30-24 (24V/1.3A), DPP50-24 (24V/2.1A) and DPP50-48 (48V/1.01A). The addition of the "UL1604" suffix to these model numbers will insure the proper UL label will be provided (e.g., DPP50-48 UL1604).

Each model can operate worldwide with a broad range of AC inputs from 85 to 264 volts AC without the need for pre-selecting the AC input range. In addition, these units will operate from a DC input ranging from 90 to 375 volts DC.

The supplies feature a low ripple and noise of 50 millivolts or less and are protected against over-current and over-voltage conditions. In addition the supplies meet EN55022 Class B EMI standards (radiated and conducted), are certified to UL/EN60950-1 specifications, are listed to UL508 and CE Marked.

The units are convection cooled and can operate at full output power over a wide temperature range of from -10°C to +71°C, with derating above 60°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.

The DPP family of DIN rail-mount power supplies is available now with prices starting at $37 in 100-unit quantities
