Variable Transformer 15A (1500VA) | 0–130VAC Benchtop Variac - SC-15M

1500VA Heavy-Duty Variable Autotransformer (15 Amp) | SC-15M

The SC-15M is a high-performance 1500VA variable autotransformer designed for heavy-duty industrial, laboratory, and DIY applications. It provides a smooth, adjustable output from 0 to 130VAC at a powerful 15 Amps, making it the ideal choice for high-draw equipment that standard 5A or 10A units cannot handle.

Why Choose the SC-15M?

• High-Current Capacity: The 15 Amp (1500VA) rating is built for larger industrial loads, motor speed control, and high-power appliance testing.

• Precision Monitoring: Features an integrated LCD digital voltmeter for real-time, high-visibility tracking of your output voltage.

• Universal Application: Ideal for CNC machinery, heating elements, and product development labs requiring reliable AC power adjustment.

• Rugged Build: Housed in a heavy-duty ventilated steel casing with dual AC outlets and a built-in fuse for circuit protection.

Technical Specifications:

• Type: Non-Isolated Variable Autotransformer

• Model: SC-15M

• Input Voltage: 117VAC @ 50/60Hz

• Output Voltage: 0~130VAC Variable

• Rated Capacity: 1500VA (15 Amp Continuous)

• Display: Digital LCD Volt Meter

Safety Note: This is a non-isolated autotransformer. While it provides excellent voltage regulation for machinery and general testing, it does not provide galvanic isolation. For vintage radio or "hot-chassis" repair, please see our Isolated collection.

Need Help Choosing the Right Amperage?

A common question for industrial and lab applications is whether a 15 Amp (1500VA) unit can replace a 20 Amp (2000VA) model.

• Check Your Continuous Load: Most standard laboratory equipment, continuous-duty bench setups, and AC motors pull under 12–15 Amps during standard operation. If your peak continuous draw is 15A or less, the SC-15M offers identical performance with the added benefit of high-precision digital monitoring.

• Precision Over Raw Amperage: Unlike legacy 20A analog models where you have to estimate your voltage adjustments, the integrated LCD voltmeter on the SC-15M allows you to dial in exact voltages safely—preventing costly testing errors on sensitive components.
