What is a variac dimmerstat used for?
A variac dimmerstat is a variable autotransformer that lets a user smoothly adjust an AC output voltage from a fixed mains input, using a rotating contact arm on a toroidal winding. In electrical and electronics laboratories it is used to supply a controllable AC voltage to test transformers, motors, heaters and power-electronics circuits at other than full line voltage, and is available in single-phase and three-phase, panel-mounted and portable configurations.
Selected Variac Dimmerstats - Model Numbers
| Product Code | Product Name |

| JA-VD-1553 | Variac Three Phase Flush Back of Panel Open |
| JA-VD-1554 | Single Phase Portable Table and Floor Mounting Enclosed |
| JA-VD-1555 | Variac Three Phase Portable Table |
Applications
| Application Area | Typical Use |
|---|---|
| Electrical laboratories | Providing adjustable AC supply for transformer and motor testing |
| Power electronics laboratories | Variable AC input for SCR/triac phase-control experiments |
| Panel-mounted installations | Flush back-of-panel variac mounting for control desks |
| Portable bench use | Table or floor-mounted enclosed units for general lab use |
Frequently Asked Questions
Should I choose a single-phase or three-phase variac dimmerstat?
Single-phase variac dimmerstats suit standard single-phase lab supplies and small motor/transformer tests, while three-phase units are used where the experiment or equipment under test itself runs on a three-phase supply; confirm the supply configuration of your lab before ordering.
What is the difference between the panel-mounted and portable variacs?
The flush back-of-panel open models (JA-VD-1552 single phase and JA-VD-1553 three phase) are for mounting in control desks. The portable models (JA-VD-1554 single phase enclosed for table and floor mounting, and JA-VD-1555 three phase table) are for general bench use.
