Core Specifications

*Output current calculated from rated capacity

Engineering Advantages

✅ Space-Optimized Design

• 40% smaller footprint vs. conventional 50kVA+ regulators (540mm³ vs. industry avg. 800mm³).

• <150kg weight enables flexible deployment in skids, vessels, and mobile labs.

✅ Precision Control

• Servo motor-driven contact system with programmable speed (0.5–10 kV/min).

• Symmetrical compensation circuit ensures linear output (±0.75% deviation).

✅ Industrial Safety

• Position indicators with terminal/protection contacts for PLC integration.

• Multi-system interlocks with control panels/secondary switches.

• Magnetic oil-level gauge with dry-run prevention.

✅ Robust Performance

• ONAN cooling sustains 60-min operation at 100% load (420V, 128.6A).

• Continuous 80% derated mode (336V, 103A) for 24/7 processes.

Technical Validation

• Thermal Design: Maintains ΔT ≤65K winding rise / ≤55K oil rise (per series standards).

• Short-Cycle Withstand: Assumed 2× current (257A) for 8 cycles (verify per test certs).

• Response Time: <80ms stabilization (servo-driven advantage).

Target Applications

► Offshore power platforms ► Containerized test labs ► Compact substations ► Military mobile units ► Skid-mounted process systems

Why Engineers Specify This Model

*"The LQDZ-54kVA delivers full-power regulation in 40% less footprint – critical for offshore platforms where space costs $12,000/m². Its servo-driven control achieves ±0.75% linearity, preventing calibration drift in confined test cells."*
