Lambda Introduces Low-Power DIN Rail Power Supplies
SAN DIEGO, CA (April 15, 2005) - Lambda has introduced a family of DIN rail-mount power
supplies available with a choice of 5-, 12-, 15-, 24- and 48-volt outputs. The low-power DPP
series is an economical solution specifically designed for light industrial applications such as
chemical processing, automotive and instrumentation.
Lambda's new DPP series consists of eight models – enclosed in rugged plastic cases –
in three package sizes. The DPP15 can provide 15 watts of power in a compact 2.95 x 0.9 x
3.81 inches, models DPP30-50 up to 50W (2.95 x 1.77 x 3.58 inches), and the DPP100 up to
100W (2.95 x 2.86 x 3.81 inches).
Each model can operate worldwide without the need for pre-selecting the AC input range.
Models DPP15-50 can accept a broad range of 85 to 264 volts AC, the DPP100 automatically
selects between 85-132VAC and 176-264VAC, and all models can accept a DC input voltage.
The new power supplies feature a low ripple and noise of up to 50 millivolts and are
protected against overload and over-voltage conditions. All models are approved to UL508,
UL60950 and EN60950 specifications. The units are convection cooled and can operate at full
power over a wide temperature range of –10°C to +60°C, derating linearly at 5% of a degree
above 60°C to 71°C.
The DPP family of DIN rail-mount power supplies is available now, with prices starting at
$40 in single-unit quantities. More information can be obtained at Lambda's Web site,
For more than 50 years, Lambda has been a leading provider of standard and custom power supply solutions.
The company's broad range of products power industrial, telecommunications, data communications, medical,
and test-and-measurement applications worldwide. Lambda's corporate headquarters is at 3055 Del Sol Blvd.,
