40 KVA Servo Stabilizer — Three Phase, Air Cooled
40 KVA · Three Phase

40 KVA Servo Stabilizer Manufacturer in India

The 40 KVA Servo Stabilizer is a three phase servo voltage stabilizer that holds your output at a precise 415V/230V ±1%, however wide the incoming supply swings. Servo Stabilizer India builds every 40 KVA unit to order — air-cooled for indoor panel rooms, with forced cooling on demand — and supplies it factory-direct across India with installation and AMC. It is sized for medium industrial and commercial loads such as CNC machines, moulding units and cold storage.

How to size a 40 KVA servo stabilizer

A 40 kva servo stabilizer is rated to deliver 40 KVA at the output. As a rule we keep 20–25% headroom above your connected load, so a 40 KVA unit is the right choice for a working load of around 32 kW. That margin absorbs the starting surge of motors, compressors and pumps without the stabilizer running hot or tripping. If your load includes several large motors that start together, send us the list — we'll confirm whether 40 KVA is enough or whether to step up to the 50 kva servo stabilizer.

At 40 KVA the air-cooled for indoor panel rooms, with forced cooling on demand. It is supplied as a three phase 415V unit with independent phase control, so it corrects each phase separately even when the incoming supply is unbalanced. Read our KVA sizing guide or air vs oil cooled comparison for more detail.

40 KVA Servo Stabilizer FAQs

The price of a 40 kva servo stabilizer depends on the phase (three phase), cooling type (air cooled) and input voltage window you need. Servo Stabilizer India builds each 40 KVA unit to order and sells factory-direct — no dealer margin. Share your load and we send a same-day quotation. Call +91 81788 87426.

A 40 KVA servo stabilizer comfortably runs a connected load of about 32 kW — we keep 20–25% headroom for motor starting surges so the unit stays cool and lasts longer. It suits medium industrial and commercial loads such as CNC machines, moulding units and cold storage. Send your machine list and we confirm the right rating.

The 40 KVA Servo Stabilizer is a three phase (415V, 4-wire) unit — standard for industrial loads of this size. For smaller single phase requirements we also build ratings up to 15 KVA.

On a three phase 415V supply the approximate full-load current is 56 A per phase. We size the input/output MCCB and bypass switch accordingly.
