The butterfly series used to be formal bronze products. The price of this series is relatively expensive, and the cost performance is not high, so the sales volume is average. Later, in order to compete for the power supply market below 300 yuan, Zhenhua successively launched Blood Snow Butterfly and War Butterfly. The characteristics of these two products are material reduction and cost reduction (Xuediefa's products are white), and the conversion efficiency of white or close to bronze can only be achieved at 230V basically. Because full voltage is no longer supported, Zhenhua honestly marked the input voltage as 200-240V on the product nameplate. Of course, this does not mean that these two power supplies cannot work at low voltage, but the output power and conversion efficiency will be reduced.
Recently, both Xuedie and Zhandie have introduced new products, which completely adopt LLC half-bridge resonance structure, and the conversion efficiency has increased to 87% (at 230 V). In addition, the Battle Butterfly series only keeps the Battle Butterfly version, and the Snow Butterfly is increased to a series, from 400W to 550W. In addition, JD.COM also sells the 85-word Butterfly series (which is also a LLC half-bridge resonant structure) for JD.COM, not for retail. Snow butterfly faces the physical store.
