Key Specifications

Critical Technical Features

✅ Military-Grade Resilience

• Survives 2x overload current (166.6A) for 8 cycles without winding damage or mechanical deformation (exceeds IEC 60076-11).

• Integrated damping resistor for safe discharge of capacitive test objects during transient states.

✅ Precision Voltage Control

• Contact-type regulation via symmetrical compensation circuitry ensures linear 0–420V output with ultra-low distortion (≤3% THD).

• Rated operation: 60 mins at 100% load (420V, 83.3A).

✅ Safety Systems

• Upper/lower position limiters prevent mechanical overtravel.

• Magnetic oil-level indicator with alarm contacts.

• Interlock compatibility with control panels.

Performance Validation

• Discharge Testing: Safely discharges capacitive loads (e.g., cables, transformers) via damping resistor during transient states.

• Thermal Design: ONAN cooling maintains safe ΔT:

• Winding rise ≤65K | Oil surface ≤55K (per previous models)

• Starting Voltage: ≤1.5% of rated (assumed from series consistency).

Industrial Applications

► High-power test benches ► Cable/filter capacitor testing ► Transformer impulse testing ► Research labs requiring 2x surge tolerance

Why Engineers Specify This Regulator

*"The LQDZ-35kVA delivers unmatched fault tolerance – sustaining 166% overload for 1.6 seconds (8 cycles). Combined with damping resistor discharge, it’s engineered for destructive testing labs where competitor units fail."*
