HPR12K-00-001 is a 12 kW rack-mounted power distribution system designed to integrate four HPS3000-9-001 power supply units into a standard 19-inch rack configuration. The system provides AC input distribution, main DC output, auxiliary DC output, and I2C/PMBus communication interfaces for remote monitoring and control. It features manual ON/OFF operation via DIP switch SW1 and remote ON/OFF capability through the PSON# signal (active low, pulled to 3.3V standby), with a power-up delay of 5 to 400 milliseconds. The HPR12K-00-001 includes multiple connectors for input power (ring lug terminals with #12 screws), output distribution, and communication, along with load-share bus capability for synchronized operation of multiple power supplies. This configuration is ideal for mission-critical applications requiring redundancy, scalability, and centralized power management in data centers, telecommunications, semiconductor equipment, and industrial systems.
