Variable Isolation Transformer 10A (1000VA) 0–130VAC with LCD Voltmeter | SC-10T-2
Product Overview: The SC-10T-2 is a heavy-duty 10A (1000VA) variable AC isolation transformer engineered by PHC Enterprise, Inc. 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 Variable Isolated Variac?
- True Galvanic Isolation: Essential for safely servicing "hot chassis" vintage electronics, tube amplifiers, and antique radios. Isolating the output from the main AC line separates the circuit reference and protects ground-referenced test tools like oscilloscopes from direct line loops.
- 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 bonded earth ground on the output receptacles?
A: The SC-10T-2 is engineered with a floating secondary output to provide true galvanic separation. This prevents dangerous ground loops when connecting grounded diagnostic instruments like oscilloscopes to unpolarized or vintage equipment under test.
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 with a separate instrument, 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 vary voltage but do NOT separate your device from mains AC line power. The SC-10T-2 combines variable voltage control with true galvanic isolation in a single benchtop unit.
Safety Note: This unit is built strictly for professional laboratory, engineering, and repair environments. Galvanic isolation separates mains reference, but technicians must still adhere to strict electrical safety protocols when working with energized circuits.
