- Page 6 (ZM-MC1) How to Use The Muti-connector, included free in every Zalman power supply, is used to supply +5V or +12V power to any additional fans that a user may wish to install. Connect it to the power supply’ s output connector (P9) and simply attach the fans to the 3-pin connectors at the other end.
- Page 7 PFC circuit. This circuit has a theoretical power factor of over 95%, accepts a full range (90VAC ~ 260VAC) of AC input, and reduces total harmonics noticeably. However, it needs a complicated EMI filter and an input source circuit, and is costly to build. Zalman Tech’s ATX /ATX12V power supply uses this type of PFC. 2) Passive PFC This type of PFC uses passive elements such as a ferrite inductor on the input source to create a countering reactance.
