M10-522-30 VARIAC

M10 Series Variable AC Voltage Supplies (Variacs)This is a family of single-phase variable AC transformers (variacs / adjustable autotransformers). They take fixed mains voltage and provide a continuously adjustable AC output from near zero up to the rated maximum voltage.Main characteristics
Input: 220/230 V or 100/115 V models available
Output: continuously adjustable
0–250 V (most 220 V input models and some 100 V input models)
0–130 V (selected 100 V input models)

Power range: 200 VA to 5000 VA
Current range: 2 A to 23 A (depending on model)
Connection options: power-cable plug or binding posts (input); 4 mm safety sockets, mains outlet, or binding posts (output)
Optional digital meter
Compact bench-style units with high efficiency
Where it is used
Electronics and electrical repair workshops
Product testing and quality-control labs
Educational laboratories (electrical engineering, vocational training)
R&D and prototype development
Motor, lighting, and appliance testing benches
Any environment where controlled AC voltage is needed
What you can do with it
Voltage ramping / soft starting
Start equipment at low voltage and gradually increase to rated voltage. Useful for motors, transformers, power supplies and sensitive electronics.
Simulate different mains conditions
Set any voltage within the range (e.g. 110 V, 200 V, 230 V, 240 V) to test how devices behave under over-voltage, under-voltage or non-standard supplies.
Controlled testing and troubleshooting
Apply a precise, adjustable voltage while monitoring current and behaviour. Ideal for finding the exact operating point of circuits or checking protection thresholds.
Powering experimental or prototype circuits
Supply variable AC power to breadboards, test jigs or custom equipment within the current and power limits of the chosen model.
Educational demonstrations
Show students the effect of voltage variation on lamps, motors, transformers and other loads in a safe, controlled way.
