AC-DC DIN Rail Power Supplies operate off 3-phase AC input.
September 30, 2009 -
Featuring 12-24 Vdc outputs, DPP120 series is rated at 120 W, while DPP240 series, rated at 240 W, and DPP480 series, rated at 480 W, offer 24-48 Vdc output. Output voltages are adjustable and all units feature biphase operation, allowing them to operate under dropped phase condition with output power derated to 80%. Operating in -25 to +71°C temperatures, they include power factor correction and overcurrent, overvoltage, and overtemperature protection with auto recovery.

TDK-Lambda Introduces DIN Rail Power Supplies That Operate with 3-Phase AC Inputs
San Diego, CA - September 2009 - TDK-Lambda has released a new series of AC-DC DIN Rail-Mount power supplies with outputs rated from 120 to 480-watts that operate off a 3-phase AC line input from 340 to 575 VAC. These models are ideal for factory automation, industrial control systems and test and measurement equipment.
Each series are available with the most popular output voltages: 12VDC and 24VDC outputs are available in the DPP120 series (rated at 120W) plus 24VDC and 48VDC outputs are available in the DPP240 series (rated at 240W) and the DPP480 series (rated at 480W). An important feature of these new units is their bi-phase operation; under a dropped phase condition they will continue to operate with the output power derated to 80%. All models incorporate power factor correction in accordance with EN61000-3-2.
Output voltages can be adjusted to allow for the voltage drop in cables and similar factors. Load regulation is ±1% when the supplies are used individually and ±5% when two supplies are connected in parallel for higher power applications.
For additional convenience in control and automation applications, the 24V model includes a voltage monitoring (DC Good) relay. The relay contacts are rated at 0.3A and they close when the output voltage is above 17.6V to 19.4VDC; this can be useful in protecting devices such as sensors and solenoids that may be unpredictable at reduced voltages, i.e., below their nominal 24V rating.
Further features of these DPP 3-phase series include over current protection, over voltage protection and over temperature protection with auto recovery. The operating temperature range of the power supplies is from -25°C to +71°C.
These new DPP 3-phase series power supplies from TDK-Lambda meet EN55022 Class B EMI standards (radiated and conducted), are CE marked, and are safety-approved to UL/EN60950-1 and UL508 specifications. All models are suitable for either TS35/7.5 or TS35/15 DIN-Rail mounting, and have a robust metal case with convenient screw terminal connections. All models carry a two-year warranty.
The DPP 3-phase series are available now and priced from $64.00 each in quantities of 1k units. For more information, please call TDK-Lambda directly at 1-800-LAMBDA-4 or view our full specs on this and other DIN Rail Mount supplies at: http://us.tdk-lambda.com/lp/products/dpp-series.htm
