Lambda Introduces 480W DIN Rail-Mount Power Supplies
SAN DIEGO, CA (November 21, 2006) - Lambda has extended its DPP family of DIN rail-mount
power supplies with the addition of a 480-watt package. The new DPP480 series provides an
especially economical solution for mid-power factory automation and process control applications.
The DPP480 series is available with a nominal output of 24 or 48 volts and can be adjusted –
using a front panel potentiometer – to compensate for cable drops. Load regulation is maintained
within a 0% to +1% window when units are used individually or ±5% when connected in parallel. Up
to three units can be paralleled when the system power exceeds 480 watts.
Pre-selecting the AC input voltage range is not required because both models operate
continuously over an input of 90 to 264 volts AC or 120 to 370 volts DC. Active power factor
correction is incorporated, ensuring full compliance to EN61000-3-2. The series also meets EN55022
level A EMI standards (radiated and conducted), is approved to UL60950 and EN60950
specifications, and is listed to UL508.
The power supplies feature a low ripple and noise of less than 100 millivolts and are protected
against over-current and over-voltage conditions. The 24-volt model includes LED indicators and
incorporates a voltage monitoring relay that is activated if the output drops below a preset level.
Both models are convection cooled and can operate at full power over a wide temperature range
of -25°C to +71°C, derating linearly at 2.5% of a degree above 56°C to 71°C.
The units are enclosed in a rugged metal case measuring 6.89 x 4.92 x 4.9 inches and will
mount on either a TS35/7.5 or TS35/15 DIN rail.
The new DPP480 series power supplies are available now, with prices starting at $145 each in
100-unit quantities. More information can be found on Lambda’s Web site, www.lambdapower.com.
