ISO-500 1:1 Isolation Transformer 500VA

The ISO-500 is a compact 500VA 1:1 isolation transformer, wound and 100% tested in our own factory in Yueqing, China. It is the entry size for buyers who need galvanic isolation for test benches, audio gear, small lab equipment, or a single sensitive appliance, and it is the model we recommend to first-time isolation transformer buyers.

Key Specifications

What You Get

• Compact 500VA size, ideal for workbench and single-device use
• True 1:1 isolation, not an autotransformer
• Screened primary for lower noise
• Copper windings, varnish-dipped
• Batch test certificate with every order

Why Choose This Model

For many buyers, 500VA is exactly the size needed: it runs a turntable, a DAC, a small amplifier, a lab power supply, or a test instrument with plenty of margin, and it does not dominate the desk. The 1:1 isolation means you plug your equipment into a clean, isolated supply, and the hum, ground loops, and common-mode noise disappear. It is also the size that teaches the value of isolation without a big investment. If your load grows later, the same range goes up to 5000VA.

Typical Applications

• Audio components: turntables, DACs, preamps, small amps
• Test benches and lab instruments
• Single sensitive appliances and electronics
• Repair shops testing equipment safely
• Home theater components that pick up hum
