Significantly upgraded in 2013, the HWS-A series now has a higher efficiency (up to 91%), a lighter weight and reduced off-load power draws. The HWS-A series has five power levels, 15W, 30W, 50W, 100W and 150W, and output voltages from 3.3 to 48V. The product is covered by a limited lifetime warranty – a first for the industry when announced in 2008 for the previous HWS generation series.
