PET2000-NAS446 is a 2000 Watt AC to DC, power-factor corrected (PFC) power supply that converts standard AC power into a main output of +12 VDC. PET2000-NAS446 utilizes full digital control architecture for greater efficiency, control and functionality. The unit includes four 450 mm long cables with 20 pin connectors. The four connectors are intended to be attached directly to individual mining load boards. This power supply meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD). Best-in-class, 80 PLUS Platinum Efficiency Auto-Selected Input Voltage Ranges: 90 - 140 VAC, 180 - 264 VAC AC Input with Power Factor Correction 2000 W Continuous Output Power Capability Output cable wire harness set included Always-On 12 V Standby Output Full Digital Controls for Improved Performance High Density Design Small Form Factor: 73.5 x 40.0 x 331.6 mm (2.89 x 1.57 x 13.05 in) Power Management Bus Communication Interface for Control, Programming and Monitoring Status LED with Fault Signaling Cryptocurrency Mining Blockchain Applications Networking Switches Servers & Routers 2 PET2000-NAS446 PET 2000 - N A Sxxx Product Family Power Level Dash Airflow Input Suffix N: Normal PET Front-Ends 2000 W A: AC S446: (Rear to front) The PET2000-NAS446 AC/DC power supply is a fully DSP controlled, highly efficient front-end power supply. It incorporates resonance-soft-switching technology to reduce component stresses, providing increased system reliability and very high efficiency. With a wide input operational voltage range the PET2000-NAS446 maximizes power availability in demanding server, network, and other high availability applications. The supply is fan cooled and ideally suited for integration with a matching airflow path. The PFC stage is digitally controlled using a state-of-the-art digital signal processing algorithm to guarantee best efficiency and unity power factor over a wide operating range. The DC/DC stage uses soft switching resonant techniques in conjunction with synchronous rectification. The always-on standby output provides power to external power distribution and management controllers. Status information is provided with a front-panel LED. In addition, the power supply can be controlled and the fan speed set via the I2C bus. The I2C bus allows full monitoring of the supply, including input and output voltage, current, power, and inside temperatures. Cooling is managed by a fan controlled by the DSP controller. The fan speed is adjusted automatically depending on the actual 2 power demand and supply temperature and can be overridden through the I C bus. Figure 1.
