CNPS (Computer Noise Prevention System) with Auto Control Cooling NMB MAT Fan
By implementing heat-sensor circuitry that controls the cooling fan's speed (rpm) in relation to the temperature within the power supply, emanating noise has
been greatly reduced. The graph below shows the CNPS characteristics of our product.

Noise Level(dB) Changes In relations to Power Supply's Internal Temperature
The graph shows that the ZM460-APS in ®Noiseless or ®Silent mode can operate when the power supply's internal temperature is kept below 56 degrees C.
This information is in compliance with the 2nd Revision of ISO7779, an international standard for noise level measurement. Results may vary for different
system configurations and/or the test environments.
mproving Power Factor & Reduced Harmonics through Active PFC

Using the Multi-Connector (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.

Strict DC Voltage Regulation & Low Output Ripple / Noise
The following figures show the ripple and noise measured from the DC output of the ZM460-APS.
¡Ø Each DC output had a 0.1¥ìF ceramic capacitor and a 10¥ìF electrolytic capacitor attached as the bypass and the oscilloscope (input impedance 1M¥Ø)
measured the waveforms at 20MHz frequency bandwidth. The waveforms may differ with varying measurement conditions.
