500VA Isolation Transformer 117VAC to 117VAC | ISO-500
The ISO-500 is a professional 500VA isolation transformer engineered for controlled AC power in electronics repair, oscilloscope troubleshooting, engineering R&D, educational labs, and audio testing. With 117VAC input and 117VAC isolated output, a floating output design, polarized 2-prong outlets, and rugged steel housing, it provides a dedicated isolated source for bench work.
Why Choose the ISO-500 Isolation Transformer?
- True Galvanic Isolation: Physical separation between the AC line and the output creates a floating source for appropriate electronics testing and repair setups.
- Oscilloscope-Friendly Floating Output: Helps reduce unintended ground paths when testing equipment with grounded measurement tools. Follow appropriate isolated-power procedures and never defeat required safety grounds.
- 500VA Bench Capacity: Provides 500VA of isolated AC power and includes a 5A fast-blow fuse for circuit protection.
- Rugged Professional Design: Heavy-duty steel housing and polarized 2-prong output outlets suit repair benches, laboratories, and technical workstations.

Frequently Asked Questions
Q: What does the ISO-500 isolation transformer do?
A: The ISO-500 accepts 117VAC and provides a 117VAC output that is physically isolated from the incoming AC line. It is rated for loads up to 500VA.
Q: Why use the ISO-500 with an oscilloscope?
A: Its floating output can help reduce unintended ground paths when the device under test is connected to grounded measurement equipment. Use qualified electrical-safety procedures and do not defeat the oscilloscope safety ground.
Q: Is the ISO-500 output grounded?
A: The output is floating and has no input-to-output ground bond. The polarized 2-prong output does not provide an Earth-ground path, so the unit should be used only by people trained in isolated-power safety.
Q: How much power can the ISO-500 supply?
A: The ISO-500 is rated for a maximum load of 500VA and includes a 5A fast-blow fuse. Keep the connected equipment within the transformer rating and follow its operating instructions.
Q: Does the ISO-500 change the voltage?
A: No. It provides 117VAC input-to-output isolation rather than stepping the voltage up or down.
