KEY FEATURES & BENEFITS
Automatic Bivolt Grid Input & Configurable 110V / 220V Output Terminal Block
Engineered with an advanced dual-voltage power architecture (L+L+PE input), the AKH-B Series automatically adapts to 220VAC nominal utility grid standards while providing a flexible dual-phase terminal block (L1, L2, N1, N2). Users can seamlessly configure independent 110VAC / 120VAC line outputs or 220VAC / 240VAC combined outputs without external transformers.
High-Frequency Double-Conversion & Unity Power Factor (PF = 1.0)
Built with high-speed digital processing and true double-conversion online topology, delivering continuous, surge-free pure sine wave power. Features unity power factor (PF = 1.0), delivering 6000W on the 6KVA model and 10000W on the 10KVA model to maximize active power capacity for modern high-density server racks and medical equipment.
Ultra-Wide Input Voltage Window (110V – 300V AC) & 0ms Transfer Time
Operates across a wide AC input range of 110VAC to 300VAC (with active power derating below 176VAC) and 50/60Hz ±6Hz frequency sensing. Eliminates unnecessary battery discharges during routine brownouts and grid spikes, guaranteeing a seamless 0ms transfer time to battery mode during total utility blackout.
Flexible 16 / 20 Battery Array Configuration & 1A–12A Adjustable Smart Charger
Supports flexible battery bus configurations set to either 16 pieces (218.4VDC) or 20 pieces (273VDC) of 12V lead-acid batteries. Long-backup (-KL) models feature an integrated high-power charger adjustable from 1A up to 12A (5A default), enabling rapid recharge for large external battery banks.
Exceptional Peak Efficiency (95.5%) & Ultra-Low Harmonic Distortion
Achieves an impressive line mode peak efficiency of 95.5% (95% full load) and up to 95.3% battery mode efficiency. Input Power Factor Correction (PFC ≥ 0.99) and ultra-low THD (≤2% linear load) reduce heat dissipation, utility electricity overhead, and power system noise.
Interactive Graphic LCD Panel & Smart Monitoring Ports (RS232 / USB / EPO / SNMP)
Equipped with a clear graphic LCD screen displaying real-time telemetry on load levels, battery percentage, operating modes, and bypass status. Standard USB, RS232, and Emergency Power Off (EPO) terminals are paired with an intelligent card slot for optional SNMP, Modbus, or dry contact network cards.
