Gutor OP2446

Brief Introduction:

The Gutor OP2446 is a modular power stage (inverter/rectifier) unit designed for insertion into Gutor PXC-series rack-mounted UPS frames. It provides pure sinewave output with <3% THD, supports N+X parallel redundancy, and is hot-swappable for zero-downtime maintenance. In some contexts “OP2446” also appears as a control board for Gutor UPS — the primary industrial identification is the 30 kVA power module for PXC systems.

Description

Technical Specifications (Power Module Interpretation):

Model: OP2446
Rated Power: 30 kVA / 27 kW (single module, pf 0.9); earlier references list 10 kVA for smaller chassis — verify with host UPS frame model
Input: 3× 380/400/415 VAC ±25%, 50/60 Hz (rectifier section)
Output: 3× 230/400 VAC ±1% (inverter section), pure sine wave
Output THD: <3% linear load; <5% non-linear
Efficiency: ≥94% online double-conversion; ≥98% in ECO mode (if enabled)
Parallel Capability: Up to 6–8 modules in N+X redundant configuration
Hot-Swap: Yes — can be inserted/removed while system is online
Battery Management: Integrated charging/discharging control; supports external battery strings (typically 240–480 VDC depending on UPS model)
Communications (inter-module): High-speed CAN bus for load sharing & phase sync
Protection Functions: Overload, short-circuit, over/under voltage, over-temperature, battery reverse polarity
Cooling: Variable-speed fans (temperature-controlled)
Operating Temperature: –10°C to +40°C (module); –20°C to +50°C storage
Relative Humidity: 0–95% non-condensing
Enclosure / Mounting: 19″ rack slide-in module, IP20 front, rear connectors
Dimensions (approx.): 3U or 4U height × 440 mm W × 500 mm D (depends on PXC frame)
Weight: ~15–25 kg per module
Certifications: IEC 62040-3, CE, UL 1778, cUL

Functional Features:

Automatic load sharing among paralleled modules via CAN bus
Front-panel LEDs indicate Run / Bypass / Fault / Module ID
Self-diagnostics at power-up; logs fault history to UPS controller

Applications:

Critical process control rooms, DCS/PLC power in refineries, power plant control system UPS, data centers requiring modular redundancy.

Installation Notes:

Only trained personnel should insert/remove modules — verify frame is in normal operation before hot-swap
Ensure battery string voltage matches UPS nominal before closing battery breaker
Tighten DC busbar connections to specified torque; check for correct phase rotation on first commissioning
