4U Low-Voltage Complete Equipment for Intelligent Computing Center

4U low-voltage equipment integrates compact power distribution and high-capacity cooling solutions to support AI, HPC, and hyperscale data centers efficiently.

Overview

4U low-voltage equipment is designed to maximize rack space while delivering high power and cooling capacity for intelligent computing centers. These systems are ideal for high-density environments where AI, HPC, or cloud workloads demand reliable, scalable, and energy-efficient infrastructure. They typically combine rack-mounted power distribution units (PDUs), coolant distribution units (CDUs), and intelligent monitoring systems in a compact 4U form factor.

Cooling Solutions

Inova NovaCool™ Rack CDU delivers 120 kW of cooling in a 4U rack, supporting AI and HPC workloads. It features N+N redundant pumps, dual power supplies, and integrated 7″ HMI with Modbus, SNMP, and web access for intelligent monitoring and control. The system ensures global compatibility with a wide input voltage range (100–240 V AC, 50/60 Hz) and includes built-in leak detection and dew-point control for safe operation . Motivair In-Rack CDU provides up to 105 kW of cooling in a 4U design, creating an isolated water loop for precise coolant flow and temperature control. It supports AI-driven workloads, HPC, semiconductor manufacturing, and hyperscale data centers, with redundant circulating pumps and flexible top or bottom rack installation .

Power Distribution

Server Technology intelligent PDUs offer AC and DC input options with voltages from -48VDC to 415V three-phase and power capacities up to 57.6 kW. Form factors include 0U vertical and 1U–4U horizontal racks, with advanced features like alternating phase technology, hot-swappable iX Controllers, ±0.5% metering accuracy, and multi-layer redundancy.
