Product Description

High Frequency 3-Phase UPS System for Seamless Power Protection & Voltage Stabilization

Advanced True Online Double Conversion Technology for Seamless Power Protection,

Zero Downtime & Voltage Stabilization

High-Reliability Design

✔ True Online Double Conversion technology ensures seamless power transfer.
✔ Generator-Compatible (requires generator capacity ≥ 2x UPS rating).
✔ Optional Output Isolation Transformer (factory-installed).
✔ Standard EPO (Emergency Power Off) for safe shutdown.
✔ Advanced MCU + DSP Dual-Chip Control for precision management.
✔ Parallel Redundancy Support (up to 3 units, parallel-capable models only).
✔ Adjustable Battery Configuration (16–20 sections, field-configurable).
✔ Programmable Charging Current (1–4A per charging module, default 4A).
✔ Two Model Variants Available (PF0.8 / PF0.9).
✔ Auto-Restart After Power Failure (disabled by default).
✔ Auto-Recovery Post-Battery Depletion upon AC restoration.

Comprehensive Protection Features

✔ Multi-Layer Safeguards: Output overload/short-circuit protection, inverter overtemperature shutdown, battery undervoltage warning, and overcharge prevention for maximum system stability.
✔ Optional Manual Bypass Switch enables maintenance without load interruption (seamless transition to utility power).

Intuitive Interface & Monitoring

✔ LCD Display: Real-time UPS status, operational parameters, and event logging.
✔ Remote Management: RS232/RS485, SNMP compatibility, and monitoring software for detailed UPS control via PC.
