M10-AC250-2 AC POWER SUPPLY

This is a laboratory/industrial isolation + variable AC power supply (often called a safety isolation transformer combined with a variac-style adjustable output). It takes standard 230 V mains and provides two independent outputs: one fixed isolated 230 V and one continuously adjustable 0–250 V, each up to ~1000 VA.Typical places / applications
Electronics / electrical repair workshops and service centers
R&D and product testing labs
Educational labs (engineering / vocational training)
Manufacturing / quality-control stations for AC-powered products
Audio, lighting, and stage equipment testing
Motor and appliance commissioning or troubleshooting
What you can do with it
Safe isolation testing
Use the fixed 230 V isolated output to power equipment under repair. Because the output is galvanically isolated from the mains, touching one side of the circuit is much safer (no direct path back through earth). Ideal for working on open equipment without residual-current devices tripping unnecessarily.
Voltage stress / ramp testing
Use the adjustable 0–250 V channel to slowly raise or lower voltage while monitoring current and behaviour. Useful for:
Finding the exact turn-on point of circuits
Checking brown-out behaviour
Soft-starting motors or transformers
Verifying over-voltage / under-voltage protection

Simulating different mains conditions
Set the adjustable output to voltages other than 230 V (e.g. 110 V, 200 V, 240 V) to test how products behave on non-standard supplies or during voltage fluctuations.
Current-limited or protected powering
The built-in over-current protection helps prevent damage when testing unknown or faulty loads. You can power devices while keeping an eye on current draw up to the rated limits (≈4 A adjustable / 4.35 A fixed).
Dual independent loads
Run one device on the fixed isolated 230 V output and another on the variable output at the same time (each up to 1000 VA, provided the total load stays within the unit’s capability).
Practical tips
Always start the adjustable channel at 0 V and increase slowly.
Do not exceed the current ratings (4 A / 4.35 A) or the 1000 VA limit on either channel.
The isolation is a safety feature for the fixed channel; treat the adjustable channel with the same caution as normal mains if it is not also isolated.
Suitable for resistive, inductive and many electronic loads within the power limits; avoid
