Optimized Product Description

Precision Voltage Control for Critical Applications
The LQDZ Series contact-type voltage regulator delivers 0-420V AC adjustable output with ≤3% waveform distortion, ensuring stable power for:

• High-voltage equipment testing labs

• Transformer commissioning (per IEEE C57.152)

• Industrial process control systems

Engineered Resilience
Featuring dual protection systems:

1. Mechanical Position Limiter: Prevents brush overtravel during adjustment

2. 200% Short-Circuit Withstand: Survives 2× rated current transient events (8 cycles) without winding deformation

Operational Reliability

• 60-minute continuous operation at full 10kVA load

• Carbon brush design reduces contact resistance by 40% vs. conventional designs

• Low-loss core steel minimizes no-load losses (<0.8% of rating)
