HWS-A series of AC-DC power supplies, comprising 5 power levels rated from 15 to 150 W and achieves up to a 3% efficiency improvement at full load (up to 91%), and up to a 4% improvement at low loads.
Off-load power consumption is considerably reduced, thereby contributing to a reduction in environmental impact. Operating from a universal input of 85 to 265V AC (47 to 63 Hz), the 15, 30, 50, 100 and 150 W models are available with nominal outputs of 3.3, 5, 12, 15, 24, and 48V DC. The 50, 100, and 150 W HWS-A models include active power factor correction and all models are compliant with EN61000-3-2. The operating temperature range is wider than its predecessor; from 14 to 122°F (-10 to 50°C) at full load, and up to 158°F (70°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.
