Topology / Control: Online double-conversion UPS with an IGBT-based inverter, fully digital architecture with twin DSP control for stable, high-quality output.
Power capability: Rated at 0.9 output power factor to deliver more usable active power for real loads.
Wide input tolerance: Input voltage range 323–478 VAC; input frequency range 45–65 Hz for better operation on unstable grids and generator supplies.
High load compatibility: Designed to handle high crest factor loads, 100% non-linear loads, and 100% unbalanced loads.
Overload strength: UPS overload capability: 110% for 60 minutes, 125% for 10 minutes, 150% for 1 minute; static bypass designed for higher overload handling.
Power quality: Voltage regulation ±1% (steady state), ±5% (transient); fast transient recovery (typical ~20 ms range); low output distortion (<1% linear, <5% at 100% non-linear).
Maintenance & serviceability: Built-in maintenance bypass and front access for spare replacement and preventive maintenance; compact footprint.
System architecture options: Supports parallel up to 6 units for scalability/redundancy; supports hot standby and dual-bus architecture (with load transfer/synchronization solutions).
Battery investment protection: Automatic battery testing, adjustable end-of-discharge settings, selectable boost charging duration, deep-discharge protection, and optional temperature-compensated charging.
Protection & resilience: Short-circuit-proof inverter, integrated back-feed dry contacts, optional lightning protection, and multiple auxiliary power supplies for redundancy on larger frames.
Monitoring & communications: Industrial protocols Modbus/Jbus and network monitoring via SNMP, plus standard dry contacts for alarms and control.
