UPS Modular 208V 15-90kVA

Power Range: 15-90 kVA

| RADIANT

RADIANT UPS is AEC’s modular three-phase, double-conversion online UPS series, available in power ratings from 15 kVA to 90 kVA.

The UPS is designed for 208 V, three-phase, 4-wire (3Ph + N + G) systems.

The system is built on 15 kW hot-swappable power modules installed in a 90 kVA frame with 6 module slots, supporting a maximum configuration of 90kW or 75 kW + 1 redundancy (5 × 15 kW active modules + 1 redundant module).

This architecture allows incremental capacity expansion and N+X redundancy, enabling module replacement without load interruption.

RADIANT operates with online double-conversion topology, delivering efficiency up to 94% and a unity (1.0) output power factor.

The system is equipped with a 7-inch touchscreen display for monitoring, configuration, and diagnostics.

Advantages

Improved Voltage Control

A 3-level IGBT inverter introduces an intermediate voltage state (OV), yielding three discrete levels: +Vdc, OV, and Vdc.

Cleaner waveform

The staircase-shaped output more closely resembles a sine wave, reducing THD and interference.

Lower Harmonic Distortion (THD)

3 level IGBT reduces THD compared to the 2-level's rough waveform, improving power quality and reducing harmonic pollution.

Lower switching stress

Smaller voltage transitions mean each IGBT experiences less stress and switching loss, allowing for the use of lower-voltage, faster devices.

Higher efficiency

With reduced losses, heat dissipation and improved waveform quality, efficiency jumps above 96%, especially in new demanding critical power applications.

UPS Modular technology N+X

Modular UPS technology revolutionizes power protection by offering scalability, flexibility, and serviceability in a single solution. Unlike traditional monolithic systems, a modular UPS is composed of independent power modules that can be added, removed, or replaced without shutting down the system.

This architecture enables N+X redundancy, where “N” is the number of modules required to support the full load, and “X” represents additional modules for backup. For example, a 50 kW load can be protected by six 10 kW modules (N=5, X=1), ensuring continued operation even if one module fails.

Touch screen Smart Display

Clear Display: A 7-inch color touchscreen provides an easy and intuitive way to control the UPS.
Secure Access: Three access levels (User, Technician, Manufacturer protect system settings.
Full Configuration: Adjust input, output, battery, communication, language, and operating modes directly from the screen.
Live Monitoring: View real-time data like voltage, load, frequency, and battery status by cell at a glance.
Event History: The UPS logs up to 10,000 events, downloadable via the built-in USB port.
Generator Ready: Advanced settings ensure stable operation and communications with diesel generators.
Custom Alarms: Set and manage dry contact alarms right from the touchscreen.
Self-Cleaning: Automatic fan cycles help remove dust and keep internal parts clean.
Waveform Display: The system periodically records inverter, rectifier, and control waveforms for diagnostics.
