Variable Isolated Transformer 10A (1000W) 0–130VAC with LCD Voltmeter | SC-10T-2
The SC-10T-2 is a heavy-duty 10A (1000VA) variable AC isolated transformer (variac) engineered for safe workbench testing, electronics repair, and lab prototyping. Featuring True Galvanic Isolation, continuous variable control from 0 to 130VAC, an integrated digital LCD voltmeter, and dual AC outlets, it delivers clean, isolated AC power for sensitive equipment.
Why Choose the SC-10T-2 Isolated Variac?
- True Galvanic Isolation for Safety: Essential for safely servicing "hot chassis" vintage electronics, tube amplifiers, and antique radios. Isolating the output from the main AC line eliminates shock hazards and protects ground-referenced test tools like oscilloscopes.
- Precision Real-Time Monitoring: Integrated digital LCD voltmeter allows instant, accurate tracking of variable AC voltage adjustments.
- Dual AC Output Sockets: Power multiple test devices or auxiliary bench tools simultaneously from a single isolated power source.
- Industrial Steel Housing: Ventilated heavy-duty steel enclosure designed for continuous commercial, repair shop, and laboratory use.

Frequently Asked Questions
Q: Why is there no grounding pin on the AC power cord or outlets?
A: The SC-10T-2 is intentionally engineered without a ground path to provide a fully "floating" isolated AC output. This is an industry-standard safety requirement for servicing vintage "hot-chassis" radios and audio gear without blowing fuses or creating dangerous ground loops with oscilloscopes.
Q: Can I use this unit to bring up old tube amplifiers or vintage radios slowly?
A: Yes. The 0–130VAC continuous variable dial allows you to slowly increase voltage while monitoring current draw, making it ideal for reforming old electrolytic capacitors and safely restoring vintage electronics.
Q: What is the difference between a standard variac and an isolated variac?
A: Standard autotransformers (variacs) vary voltage but do NOT isolate your device from mains AC line power. The SC-10T-2 combines variable voltage control with true galvanic isolation in a single unit for maximum bench safety.
