Eaton 91HD (9EHD Gen2)

Configuration / Range: 3-phase input, single-phase output (3:1) industrial UPS, 10–200 kVA class (model range).
Industrial-grade reliability: Designed for harsh environments (dust, humidity, corrosive gases) with protected PCB design, independent cooling airflow, and anti-dust structure.
Isolation for safer loads: Output isolation transformer as standard to reduce load harmonics impact and improve electrical safety; input isolation transformer optional for improved immunity to grid transients and reduced harmonic pollution to the mains.
Full digital control: DSP-based control for rectifier, inverter, and static switches, improving protection and stability.
Redundancy built-in: N+1 control power supply and fan redundancy with automatic fault detection for stable full-load operation.
Strong overload capability: 110% continuous; 125% for 10 min; 150% for 1 min.
User-friendly HMI: 7-inch industrial color touchscreen + LED indicators for quick access to input/output/load/battery status and alarms.
Connectivity: Standard Modbus / RS232 / RS485 and dry contacts; optional industrial network card supporting modern cybersecure networking standards.
Electrical (typical): Main input 380/400/415 Vac (3-phase + PE), wide voltage window; bypass input single-phase 220/230/240 Vac; output single-phase 220/230/240 Vac with ±1% regulation and low distortion (linear load).
Efficiency & scalability: Inverter mode high-efficiency design; ECO mode up to 96%; parallel up to 8 units (configuration dependent).
