LQDZ-100KVA Contact Type Voltage Regulator: Precision High-Voltage Control

Advanced Voltage Regulation for Industrial Applications

The LQDZ-100KVA contact voltage regulator delivers precision voltage control from 0.38kV input to 0~3.3kV output. Engineered for critical industrial environments, this single-phase (50Hz) regulator features symmetrical compensation technology and reversed polarity voltage regulation to ensure linear, stable output with ≤3% waveform distortion. With ONAN cooling and electrical drive operation, it maintains consistent performance under 100kVA load for 60+ minutes.
