Description

High-Power Oil-Immersed Contactless Voltage Stabilizer

High-power oil-immersed inductive contactless voltage stabilizers adopt microcomputer control technology and are manufactured with customized components and high-quality electrical materials. Without wearing parts such as carbon brushes, mechanical chains or spark-generating contacts, they feature strong voltage regulation, low power consumption, long service life and maintenance-free operation. They are widely used for voltage stabilization of high-precision equipment and whole-facility power conditioning.

Application Scenarios:
   This series of voltage stabilizers generates no interference signals and is suitable for various equipment and sites, including color printing machines, computerized vacuum coating machines, SMT equipment, CNC machines, EDM machines, high-end precision equipment, large machine tools, whole-factory power systems, highways, mine tunnels, and more.

   Product Features:
   1. Wide voltage regulation range: ultra-wide input range, fast response and high precision.
   2. Contactless and wear-free: equipped with inductive voltage regulators (IVR) as core components; no carbon brushes, mechanical chains or spark contacts, with a service life of more than 15 years.
   3. Dual-loop control system: adopts large-scale integrated circuits with automatic switching between dual control systems, greatly improving reliability and ensuring stable output voltage for normal load operation.
   4. LED digital display: clearly shows input voltage, output voltage, load current and other electrical parameters.
   5. Strong preset functions: output voltage, regulation accuracy and protection thresholds can be set freely.
   6. Stepless voltage regulation (brushless): linear and stable output without step changes.
   7. Sufficient capacity and strong loading capacity: supports 100% load and continuous operation.
   8. Excellent performance: uses Japanese high-permeability silicon steel sheets to minimize no-load/load losses and no-load current.
