centers, cutting machines, precision devices, EV charging stations,
generators and motor testing, it delivers stable voltage control to
eliminate fluctuation risks and protect critical industrial
equipment.
Features & Advantages
Our three phase oil-immersed variac delivers industry-leading
performance with core strengths of ±1% output precision, ultra-fast
voltage response, long service life, low energy losses, full
capacity output and a wide 0-1300V adjustable voltage range
(customizable). Its oil-immersed design enhances insulation and
heat dissipation, paired with a porous cooling structure and
built-in fans to rapidly reduce operating temperature. Premium core
components include 100% pure dull purple copper coils for accurate
regulation and non-derated power, a heavy-duty drive motor for fast
brush adjustment, high-conductivity double carbon brushes with
minimal abrasion, and high-insulation reliable terminals for safe,
convenient wiring. It also features a multifunctional digital
display panel, high-security cabinet lock, and produces no
additional waveform distortion for full compatibility with
sensitive precision equipment.
