Powering the next generation of AI data centers
Modern data centers are evolving from traditional IT facilities into high-performance AI infrastructures, where power has become just as critical as compute. As AI workloads continue to increase in size and complexity, operators are adopting more efficient power architectures, including 800 VDC distribution, solid-state transformers and integrated energy storage. These next-generation designs reduce conversion losses, improve scalability and enable the high power densities required by modern GPU clusters. This transition creates new opportunities, but also introduces new challenges because they place greater demands on protection and power management. This makes ultra-fast, intelligent DC protection essential for ensuring maximum uptime, efficiency, safety and reliability. Reliable DC protection is becoming a critical part of every future-ready power architecture.
Astrolkwx combines decades of experience in power electronics with proven DC protection technologies to support the next generation of AI-driven data centers.
Single module air-cooled SSCB
Rack-internal protection. An ultra-fast, air-cooled SSCB designed to protect individual server hardware within the rack. It manages directional current flows between 125A and 300A, isolating faults instantly before they can impact neighboring hardware.
Single-module water-cooled SSCB
Rack-level freeder protection. A single-module, water-cooled SSCB built to safeguard the main power feed of a complete compute rack. Handling directional currents from 1,250A up to 1,500A, it prevents localized rack faults from cascading into the wider DC grid.
Single-module or multi-module water-cooled SSCB
Battery Energy Storage System (BESS) Protection. Designed for bidirectional power flows between 1,500A and 3,000A. This single- or multi-module water-cooled SSCB provides high-speed directional protection, safely managing the heavy charge and discharge cycles of the battery backup.
Single-module or multi-module water-cooled SSCB
Main DC distribution zone protection. A high-capacity, multi-module water-cooled SSCB serving as the main breaker for entire rows or zones. It features fully bidirectional current and protection capabilities (2,500A to 10,000A) to clear massive fault currents anywhere in the data hall distribution.
Multi-module water-cooled SSCB
The ultimate line of defense at the main power input. This heavy-duty, multi-module water-cooled SSCB manages currents up to 10,000A. It isolates the entire DC data hall from the Solid-State Transformer (STT) grid connection in microseconds during a catastrophic event.

Expertise in modern DC power architectures
Future data centers require more than efficient power conversion. They demand intelligent power distribution that safely integrates renewable energy, battery storage and high-density AI workloads.
We support customers developing advanced DC infrastructures, including:
- 800 VDC and future 1500 VDC power architectures
- Solid-State Transformer (SST) based systems
- Common DC bus and multi-bus topologies
- Battery Energy Storage System (BESS) integration
- High-power DC protection and fault isolation
Proven DC protection technology
Protecting a DC network is fundamentally different from protecting an AC system. Without a natural current zero crossing, faults develop extremely fast and require protection technologies capable of interrupting fault currents within microseconds.
Our portfolio includes proven solutions for mission-critical DC applications, including:
- Ultra-fast solid-state DC breakers
- Latching current limiters
- Liquid- and air cooled rectifiers
- Super capacitors
- High power resistors
