The SKB AVR-5000 PRO is a high-capacity voltage stabilizer using a toroidal transformer with a servomotor for precise, continuous voltage correction. It accepts an input range of 140–260 V and delivers a regulated 220 V output through a terminal block connection, making it suitable for hardwired appliance circuits.

The white metal enclosure houses all components, and an LED display provides real-time operational status. Built-in protection covers overvoltage, undervoltage, overload, overheat and short circuit, with configurable delay timers to prevent rapid cycling.

Key Features

• Toroidal transformer with servomotor for continuous, high-precision voltage correction
• Input voltage range: 140–260 V
• Terminal block output connection
• Multi-mode protection: overvoltage, undervoltage, overload, overheat, short circuit
• LED display for operational status
• Built-in delay times: 6/180 sec

Product Benefits

• The servomotor-driven toroidal transformer provides tighter output regulation than relay-switched or static designs, maintaining 220 V even during gradual voltage drift
• At 5000VA/3000W, the AVR-5000 PRO can protect high-consumption appliances — such as large air conditioning units, industrial refrigeration and power tools — that smaller stabilizers cannot handle
• Terminal block output enables permanent hardwiring into a dedicated circuit, eliminating socket-adapter intermediaries
• The combination of overvoltage, undervoltage, overload, overheat and short circuit protection provides five distinct safety layers for connected equipment

Why You'll Love It

• The toroidal + servomotor combination is a step up from relay-based stabilizers — it regulates output voltage continuously rather than in discrete steps, resulting in smoother, more accurate output
• At 13.7 Kg the AVR-5000 PRO is robust yet manageable enough for a single technician to install beside a large appliance
• The 5000VA rating future-proofs the installation — as appliances are replaced with higher-wattage models, the stabilizer does not need to be upgraded
• LED status feedback provides instant confirmation of normal operation without requiring the user to measure voltage with external equipment
