Lambda Adds 180W Single-Output Power Supply that
Delivers 9.6W per Cubic Inch in a 3- x 5-inch Footprint
SAN DIEGO, CA (May 31, 2005) - Lambda has introduced a 180-watt single-output power
supply that delivers an exceptional 9.6 watts per cubic inch in an industry-standard 3- x 5-inch
footprint, up to 90% efficiency, and excellent EMC performance. Part of Lambda's NV-Power
series of high-density, environmentally friendly AC-DC power supplies, the new NV-180 is ideal
for use in high-density medical, process control and test-and-measurement equipment.
The NV-180 is built on Lambda's patented multiple resonant topology (MRT), which
uniquely uses synchronous rectification to achieve the supply's high efficiency and allows
significantly reduced power loss without compromising size for power.
The new power supply is a very compact 3 x 5 x 1.25 inches – making it compatible with
1U enclosures. Moreover, its simple open-frame construction and absence of power
components on the underside of the board make the unit easy to cool.
The Lambda NV-180 is initially available with outputs of 5, 12 and 24 volts and with
currents up to 25 amps. It is also available with an optional high-power standby output rated at
5 volts, 2 amps; remote on/off; and power good signal. In addition, a cover option may be
Because of its soft-switch MRT design, the NV-180 has inherently low emissions, aided by
the use of silicon carbide Schottky diodes. The new power supply has EN60601 medical
approval combined with EN55022 Level B conducted emissions – unique for this class of
product – as well as EN61010 and EN60950 approvals.
The NV-180 is available now, priced at $89 each in 100-unit quantities. More information
is available at Lambda's Web site, www.lambdapower.com.
