1000W Power Supply Features Medical Approvals
SAN DIEGO, CA (July 15, 2008) - Lambda has expanded its successful SWS series of single output AC-DC power supplies with the introduction
of the medically-approved 1000W units. The new SWS1000L can be supplied with the choice of a 5V, 12V, or a 24V output. The 24V model has a
peak output power of 1224W. Lambda will extend this series very soon to offer more output voltage selections between 3.3V and 60V. The
SWS1000L models have a 4kVAC input to output isolation and low leakage current (<300μA) while retaining Class B conducted and radiated EMI
performance. These high voltage isolation and low leakage specs are requirements of the medical safety standards per EN/UL60601-1; making
these supplies ideal for applications such as automated pharmaceutical dispensers, blood analyzers and gene/DNA analysis equipment.
These supplies have a low profile of only 2.4 inches. The operating temperature range is from -20 up to +74°C. In addition, these supplies
feature a low-temperature start-up capability with a 100% load, as low as -40°C; making these a reliable choice for systems that experience
extremes of temperature such as outdoor-mounted equipment including LED displays/signage, automated toll booths and traffic controls. In addition,
these power supplies feature a temperature-controlled fan, which minimizes acoustic noise (up to 8 dBA less than competitive units) under
typical operating conditions. This feature makes the SWS1000L ideal for powering indoor systems beyond medical or laboratory equipment, such
as automated self-serve kiosks, automatic test (ATE), factory automation and mechatronics.
Each model accepts a wide input range of from 85 to 265VAC, making them compatible with global power standards. The SWS1000L features a wide
output voltage adjustment range of up to ±20% to accommodate non-standard system voltages, while an external voltage programming feature
(1 to 6V input) enables the supplies to be adjusted remotely from 20% to 120% of its nominal output voltage on most models. This unique feature
allows the SWS1000L to be used as an inexpensive bench or laboratory power supply.
Other important features include a 12V@ 0.1A auxiliary output, fan fail alarm, DC output good signal and active current sharing for paralleled
connected units. Lambda has included protections for over-voltage, over-current and over-temperature conditions. The SWS1000L series is CE
marked and carries UL, CSA, EN60950-1, EN60601-1, UL60601-1 and EN50178 safety approvals and complies with MIL-STD-810F for vibration and shock.
All models conform to EN55011-B, EN55022-B and FCC-B for conducted and radiated EMI as well as EN61000-4 immunity and EN61000-3-2 Class A power
factor and harmonic distortion specifications.
The SWS1000L series are available now and priced from $460 each in 50-unit quantities. For more information visit Lambda's web site at:
