The SKB AVR-3000 is a linear (IE-core) transformer voltage stabilizer designed to protect household electrical appliances from damage caused by voltage surges, sags and fluctuations in the mains supply. It accepts an input range of 140–260 V and delivers a regulated 220 V output through a terminal block connection.

The white metal enclosure houses the IE-core transformer with a single terminal block output for direct wiring. An LED display provides visual status indication, and protection covers overvoltage, undervoltage, overload, overheat and short circuit scenarios.

Key Features

• IE (linear) transformer for straightforward voltage stabilisation
• 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 to prevent rapid cycling

Product Benefits

• The 3000VA/1800W rating handles higher-consumption appliances — such as air conditioners, refrigerators and washing machines — that lower-rated stabilizers cannot support
• The wide 140–260 V input tolerance provides robust protection across the full range of voltage irregularities found in domestic and rural networks
• Terminal block output allows the stabilizer to be wired directly into an appliance's power circuit for a clean, permanent installation
• Overheat and short circuit protection provide automatic safety cutoff in fault conditions, without requiring manual reset

Why You'll Love It

• The 3000VA/1800W capacity makes the AVR-3000 suitable for protecting large household appliances that a 2000VA unit would overload
• Terminal block output gives installers the flexibility to hardwire the stabilizer into a dedicated appliance circuit for a permanent, tidy installation
• The 6/180 sec delay timers prevent the rapid switching that could occur when mains voltage oscillates around a threshold, protecting both the stabilizer and the connected appliance
• LED status display confirms at a glance that the unit is active and operating within its regulation range
