Stabimatic Vanguard-45 3-Phase Automatic Voltage R...

The Stabimatic Vanguard‑45 3‑Phase Automatic Voltage Regulator is a robust and high‑performance servo‑type AVR designed to deliver stable, clean, and consistent power in environments with unreliable mains voltage. Built for industrial, commercial, and heavy‑duty electrical systems, this regulator ensures your machinery and sensitive equipment operate safely and efficiently even when input voltage fluctuates dramatically.

Featuring a wide input voltage tolerance from 190 V to 450 V (three‑phase), the Vanguard‑45 maintains regulated output voltage at stable 380 VAC with selectable 220 VAC options — making it suitable for a broad range of three‑phase electrical loads. Its independent 3‑servo motor controllers continuously monitor and adjust each phase to balance and stabilize power in real time.

The built‑in digital display panel shows both input and output voltage & current for all three phases, as well as load and overload status — giving you immediate, accurate insights into system performance. Constructed with 99.99 % pure copper transformers, the unit maximizes efficiency and durability, even under continuous operation.

Safety is paramount; the Vanguard‑45 includes surge protection, short‑circuit protection, no‑phase detection, and an alarm system when operating in protection mode. Devices are safeguarded against abnormal supply conditions, ensuring less downtime and longer equipment life. A manual bypass adds flexibility for maintenance, bypassing the regulator when needed without disrupting power.

Designed for demanding power environments, the Stabimatic Vanguard‑45 AVR is an ideal solution where voltage stability is essential — from factories and industrial plants to commercial facilities and critical electrical infrastructure.
