Form Factor / Mounting Type
Standardized 19-inch rack-mounted casing (2U to 3U profile), designed for standard server cabinet integration.
Intelligent Communication Expansion
Graphic LCD display with RS-232, USB and EPO ports; optional SNMP / Modbus cards enable real-time PC and mobile remote management.
Battery Quantity Customization
Highly flexible hardware battery mapping (configurable for 16, 18, or 20 units on 6KVA/10KVA models).
KEY FEATURES & BENEFITS
High-Frequency Double-Conversion Online Topology with 0ms Transfer
Engineered with advanced DSP digital control and double-conversion online architecture, delivering continuous, uninterrupted pure sine wave power to mission-critical IT equipment. Zero transfer time (0ms) from utility grid to battery mode eliminates server reboots and data corruption during power outages.
Unity Output Power Factor (PF=1.0) & Maximum Active Power Yield
Provides unity output power factor (PF=1.0, e.g., 3KVA=3000W, 10KVA=10000W), maximizing usable active wattage for modern high-density server racks and active PFC blade servers without power derating.
Ultra-Wide AC Input Range (110Vac–300Vac) & Active PFC (PF ≥0.99)
Tolerates extreme voltage fluctuations (110Vac to 300Vac) without switching to battery power, preserving battery lifespan for genuine blackout emergencies. Input power factor corrector (PFC ≥0.99) reduces grid distortion and lowers operational electricity costs.
19-Inch Rack / Tower Convertible Enclosure
Designed for versatile deployment in standard 19-inch IT equipment cabinets, network racks, or freestanding tower configurations. Space-saving rackmount form factor optimizes rack U-space while featuring a rotating LCD control panel for easy viewing.
Adjustable Strong Charger (1A–12A) for Long-Backup (-L) Configurations
Long-backup models (-L) feature powerful 1A to 12A digitally adjustable AC chargers, capable of rapidly recharging high-capacity external lead-acid or LiFePO4 battery banks to ensure multi-hour runtime during extended utility outages.
Comprehensive Smart Ports (USB / RS232 / EPO / Optional SNMP)
Equipped with USB, RS232, and Emergency Power Off (EPO) terminals as standard. Supports optional SNMP network cards and dry contact relay cards for centralized remote monitoring, automated server shutdown, and cloud telemetry.
