Lambda Introduces 1800W, 3-Phase AC to DC Industrial
Power Supplies with 5-Year Warranty
SAN DIEGO, CA (July 26, 2007) - Lambda has introduced a new family of 1800-watt
power supplies with a five-year warranty. The single-output HWS1800T series are ideal for
powering industrial equipment used in applications that demand long field-life and ultra-high
These 3-phase AC to DC power supplies are available in ten popular output voltages:
3.3V, 5V, 6V, 7.5V, 12V, 15V, 24V, 36V, 48V and 60Vdc. To accommodate non-standard
system applications the 3.3V to 36V models can be adjusted ±20% and the 48V and 60V
supplies can be adjusted +10/-20%. The 24 volt and higher output voltage supplies feature a
remarkable peak power of 2520-watts. For example, the 24-volt supply is rated at 75 amps and
has a peak current capability of 105 amps.
The HWS1800T series accepts a wide range of 3-phase input voltages, from 170 to
265VAC (47-63Hz) and meets the tough SEMI F47 power line sag specifications. Remote
On/Off, Remote Sense, Remote Adjust, DC Good and single-wire Current-Share controls and
signals are standard. In addition, a front panel mounted Green LED is lit when the supply is on.
Overcurrent, overvoltage and over-temperature protection is also provided.
The power supplies feature a high-quality internal fan and can be operated in a -10°C to
+70°C ambient environment. The units come in a compact footprint of 4.98 x 3.23 x 11 inches,
making them suitable for mounting in a 2U rack. Key applications include factory automation,
semiconductor fabrication and automatic test equipment (ATE).
The new Lambda power supplies meet FCC Class A and EN55011/55022-A EMI
standards (conducted and radiated) and are safety-approved to UL/CSA60950-1 specifications.
They also meet IEC61000-4-2-X immunity standards and are RoHS-compliant.
The HWS1800T series are available now and priced from $1295 each in 50-unit
quantities. More information can be found at Lambda's Web site: www.lambdapower.com.
