AC-DC Power Supplies

Description

TDK Corporation announces the introduction of the TDK-Lambda HWS-A series of AC-DC power supplies, comprising of five power levels rated from 15-150W. The HWS-A is a significant refresh of the established HWS series, which was originally introduced in 2005, and is completely form, fit and function compatible with the existing series to enable an easy upgrade. The new series 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.  Product weight has also been reduced by up to 12%. Operating from a universal input of 85-265Vac (47-63Hz), the 15, 30, 50, 100 and 150W models are available with nominal outputs of 3.3, 5, 12, 15, 24 and 48Vdc. The 50, 100 and 150W HWS-A models include active power factor correction and all models are compliant EN61000-3-2. The operating temperature range is wider than its predecessor; from -10 to +50°C at full load, and up to 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.
