In an automated manufacturing environment, even a brief power interruption poses serious risks. It can result in production downtime, equipment damage, data loss, and significant financial losses. Factory equipment includes CNC machines, robotic production lines, PLC control systems, automated packaging equipment, and industrial servers. These systems require a continuous and stable power supply to maintain operational efficiency.
Prostar ET100K HV stable power 100kva ups system is specifically designed to provide reliable backup power for industrial machinery and critical factory operations. With advanced online double conversion technology, this online UPS system continuously converts incoming AC power to DC and back to clean AC. This means zero transfer time, zero output distortion, and complete isolation from grid noise, sags, surges, and frequency drift. For facilities that demand reliable backup power for industrial machinery, this architecture is non-negotiable.
Manufacturing facilities often face various power quality issues, including:
Heavy industrial loads frequently cause voltage instability. Motors, compressors, and welding equipment can create sudden voltage drops that affect sensitive electronic systems.
Grid failures, transformer faults, and severe weather conditions can lead to unexpected production stoppages.
Modern industrial equipment generates harmonics that can negatively impact power quality and reduce equipment lifespan.
As factories adopt Industry 4.0 technologies, stable power becomes increasingly important for networked equipment, industrial computers, and automated control systems.
A high-performance 100kVA UPS system helps eliminate these risks and ensures continuous production.

Prostar ET100K HV is a premium 100kVA UPS system engineered for demanding industrial environments.
The system continuously converts incoming AC power into DC and then back into clean AC power. This online double conversion UPS architecture completely isolates connected loads from utility power disturbances.
Your factory can get:
The ET100K HV supports 480V three phase UPS system applications, making it suitable for large industrial facilities and heavy-duty equipment.
Industrial power grids often experience voltage fluctuations and frequency instability, especially in manufacturing facilities with heavy electrical loads.
The ET100K HV 100kVA UPS system supports a wide input voltage range and frequency range, allowing the UPS to continue operating normally without unnecessarily switching to battery mode. This feature significantly extends battery life while improving overall system reliability.
Benefits are including:

The ET100K HV adopts a bottom cable entry structure for simplified installation and maintenance.
This design is particularly beneficial in industrial environments where power cables are routed through cable trenches or raised floors.
Advantages:
Factory equipment often experiences temporary load surges during startup, motor acceleration, or process switching.
The 480V three phase UPS system provides exceptional overload performance to maintain stable operation under demanding conditions.
| Load Condition | UPS Performance |
| ≤ 105% Load | Continuous operation |
| 105% – 125% Load | Transfers to bypass after 10 minutes |
| 125% – 150% Load | Transfers to bypass after 1 minute |
This super overload capacity protects critical production equipment while preventing unnecessary system shutdowns.
Industrial benefits:
As manufacturing operations grow, power requirements often increase.
The UPS system for manufacturing facilities supports parallel-redundant operation with up to 8 units connected in parallel, providing exceptional scalability and system availability.
Users can gradually increase UPS capacity without replacing existing equipment.
Additional UPS modules can be installed to create fault-tolerant systems, ensuring continuous operation even if one UPS unit becomes unavailable.
Parallel redundancy minimizes the risk of production interruptions caused by power system failures.
The system works seamlessly with diesel generators, providing stable power during extended utility outages.
When utility power fails, the 100kVA UPS system instantly draws energy from the battery bank without any interruption to connected equipment.
The UPS continuously regulates output power, ensuring sensitive equipment receives stable voltage regardless of utility conditions.
Advanced filtering technology minimizes harmonic distortion and delivers clean power to critical loads.
The UPS conditions generator output power and eliminates fluctuations before supplying power to protected equipment.

These indicate the load has exceeded the KVA rating of the SCRs (Static Switches).
Action:
The UPS logic compares the phase angle of the Inverter vs. the Bypass. If they are 120° out of sync, the “Static Switch” cannot transfer without damaging the load.
Action:
The Rectifier (SCR or IGBT based) synchronization depends on the “Zero Crossing” of the input waves. Wrong sequence prevents the Rectifier from firing correctly.
Action:
If only one phase (e.g., Phase A) reports an error, it is likely a local distribution issue or a “Neutral Drift.”
Action:
Fans stop and alarm.
