AC-DC power supplies for factory automation, process control introduced by TDK Lambda
SAN DIEGO, 4 March 2014. TDK Lambda Americas Corp. in San Diego is introducing the HWS-A series of AC-DC power supplies for factory automation, process control, broadcast and communications, test and measurement, and LED signage applications.
The HWS-A series of power electronics devices comprises five power levels rated from 15 to 150 Watts. The series achieves power efficiency of as much as 91 percent at full load, and as much as 90 percent improvement at low loads. Off-load power consumption is reduced, and product weight also has been reduced by 12 percent.
Operating from a universal input of 85 to 265 volts AC, from 47 to 63 Hz, the 15-, 30-, 50-, 100-, and 150-Watt models are available with nominal outputs of 3.3, 5, 12, 15, 24, and 48 volts DC. The 50-, 100-, and 150-Watt HWS-A models include active power factor correction and all models comply EN61000-3-2.

The HWS-A is a refresh of the established HWS series, which originally was introduced in 2005, and is form, fit, and function compatible with the existing series to enable upgrades. The operating temperature range is from -10 to 50 degrees Celsius at full load, and to 70 degrees C with appropriate derating.
All models meet EN55011/EN55022 and FCC curve B requirements for conducted and radiated EMI and at high line input, the HWS-A meets the requirements of SEMI F47. The TDK-Lambda HWS-A series is approved to the safety standards of UL/CSA/EN 60950-1, UL508 (with cover), is CE marked according to the LV and RoHS Directives and comes with a limited lifetime warranty.
