DC to AC Inverters

Power Innovations International's inverter modules convert high voltage DC input power to pure sine wave AC power, and are configurable via command from a shelf controller. Multiple inverter modules can be arranged to operate in parallel or to be phase-shifted to create 3-phase power systems in a power shelf, and support Modbus RS-485 communication. With demonstrated near-continuous uptime and ease of installation, these inverters are easily implemented into data center environments. Pii offers 3-slot power shelves for all modules, as well as shelf controllers and power management controllers.

1. Inverter Modules +
Our core inverter modules convert high voltage DC input power to pure sine wave AC power. Configurable via command from a shelf controller, they deliver highly reliable output suitable for data center environments.
Return to System Overview
2. Power Shelves +
Robust 3-slot power shelves act as the foundation for the system, allowing multiple inverters to operate in parallel or to be phase-shifted. This enables highly scalable three-phase output that adapts seamlessly to your infrastructure demands.
Return to System Overview
3. Shelf Controllers +
Installed directly into the power shelf, these dedicated shelf controllers manage the local inverters to ensure precision output. They provide critical constant power, constant current, and constant voltage regulation.
Return to System Overview
4. Power Management Controllers +
The Power Management Controller (PMC) manages inverters via Modbus RS-485. It connects to the upstream system controller via Ethernet to configure parameters, collect data, and orchestrate the entire power shelf.
