What is a UPS 15kVA 3 Phase?

A UPS 15kVA 3 phase is an uninterruptible power supply designed to deliver 15kVA capacity across three-phase electrical systems. It provides:

Continuous, clean power via double conversion technology
Protection against blackouts, surges, sags, and harmonics
Seamless transition to battery during outages
Stable output for industrial-grade equipment

As a true UPS 15kVA 3 phase unit, it provides 15,000 Volt-Amperes of apparent power. It typically supports a real power load of roughly 12kW. It serves as a firewall between your sensitive equipment and the unpredictable utility grid. This eliminates risks from surges, sags, frequency variations, and total blackouts.

Why Choose ET15K HV UPS 15kVA 3 Phase?

True Online Double Conversion Technology

The ET15K HV reliable industrial UPS 480V uses online double-conversion topology, ensuring:

Zero transfer time
Pure sine wave output
Complete isolation from grid disturbances

This guarantees consistent power quality, even in unstable grid environments.

480V High Voltage Design

Designed for high-voltage industrial applications, the 480V configuration offers:

Reduced current losses
Higher efficiency in power transmission
Compatibility with heavy-duty machinery

It manages 480V 3-phase loads with precision. This makes it ideal for North American industrial standards. It is also perfect for heavy-duty machinery that requires stable, high-tension power.

Built-in Isolation Transformer

A key differentiator of this UPS 15kVA 3 phase ups system is its integrated isolation transformer, which provides:

Electrical isolation between input and output
Enhanced safety for sensitive equipment
Superior noise suppression
Improved load compatibility

Advanced DSP Control Technology

The industrial ups system integrates digital signal processor (DSP) control, enabling:

High-speed response to load changes
Precise voltage and frequency regulation
Intelligent fault diagnostics
Enhanced system stability

Intelligence Meets Resilience

Equipped with an intuitive LCD interface and remote monitoring capabilities (SNMP/Modbus), your facility managers can track real-time health metrics. It doesn’t just provide backup; it provides data-driven reliability.

UPS with Transformer Diagram

The 15kVA transformer-based UPS, the internal inverter drives the primary winding of the output transformer. This physical separation between the DC bus/battery and the AC load ensures a unique layer of protection. Electronic circuits alone cannot match this protection. The transformer creates a physical “air gap” between the input source and the output load. This protects sensitive equipment from DC offsets, common-mode noise, and catastrophic faults on the utility line.

FAQ

Q1: Can the ET15K HV UPS system operate on 208V or 380V?

The “HV” model is specifically optimized for 480V nominal systems. Some universal models support a wide range. However, using a dedicated 480V unit like the ET15K HV ensures optimal efficiency. It also ensures component longevity for high-voltage infrastructures. For 208V/380V needs, a different model variant should be selected.

Q2: Can a UPS 15kVA 3 phase handle unbalanced loads?

Yes, advanced ups systems like ET15K HV support 100% unbalanced loads, ensuring stable performance in real-world conditions.

Q3: Can this high voltage UPS 480v handle motor loads?

Absolutely. Many UPS systems struggle with the inrush current of motors. However, Prostar ET15K HV’s robust inverter is specifically designed to handle the dynamic loads common in manufacturing environments.

Q4: Can the ET15K HV industrial ups 15kva 3 phase be paralleled for redundancy?

Yes. The ET15K HV industrial ups 15kva 3 phase supports up to 4 units in parallel (N+1 redundancy or capacity expansion). This allows for 45kVA/45kW of total capacity or the ability to lose one unit without disrupting the critical load.

Q5: Is the ET15K HV 15kVA UPS compatible with lithium-ion batteries?

Absolutely. The UPS features a configurable charge voltage and current profile. It is compatible with both traditional lead-acid (VRLA) and modern Lithium Iron Phosphate (LiFePO4) batteries. This offers a longer lifespan and faster recharge times.
