UPS System 250KVA Features
3-Phase Output
The three-phase output provides balanced power distribution. This not only improves performance but also increases the lifespan of connected equipment. It minimizes wear and stress on electrical systems.
True Online Double Conversion Design
The UPS system adopts an advanced online double conversion topology. This provides continuous power conditioning. It eliminates surges, spikes, and harmonics from the incoming AC supply. The load is always supplied from the inverter, guaranteeing clean and stable output.
Intelligent Battery Management
Equipped with smart battery charging and monitoring, the 3 phase 250kva ups system optimizes battery performance and prolongs service life. It supports multiple battery configurations and real-time status reporting.
Industrial-Grade Design
Heavy-duty metal enclosure with superior heat dissipation, designed to withstand high ambient temperatures, dust, and continuous operation in demanding environments.
User-Friendly Interface
Features a large LCD touchscreen for easy monitoring of system parameters, alarms, and diagnostics. Remote management capabilities via SNMP, Modbus, or web-based interfaces allow for proactive oversight from anywhere.
Comprehensive Surge and Transient Protection
Built-in surge suppression safeguards against lightning strikes, power surges, and transient voltage spikes. The system includes metal oxide varistors (MOVs) and gas discharge tubes for multi-stage protection.
