Description
It Cuts the Power Before the Voltage Damages Anything.
5 KVA · 140–270 V · Digital · 2 Ton.
Bluebird's 2-ton stabilizer, and the most capable unit in the range · high-low voltage cut-off — when the supply goes beyond what any stabilizer can safely correct, it disconnects the AC entirely rather than passing the fault through · a digital display showing input and output voltage live, so you can actually see what your supply is doing · microcontroller-based sensing for faster, more accurate correction than relay-only designs · 100% copper winding for lower heat and longer life · a 5 KVA rating for one AC up to 2 ton, inverter or fixed-speed · a 140 V to 270 V input range · a vacuum-coated transformer that runs cooler · wall mount or floor standing · made in India · 2-year warranty
Hi-Lo
cut-offknows when to give up
Every stabilizer has a limit, and what it does at that limit is the thing worth paying for. Within its range this unit corrects the voltage and passes clean power to the AC. But when the supply goes beyond what can be safely corrected — a severe sag, a spike, a neutral problem — a basic stabilizer simply passes it through, and your compressor takes it. High-low voltage cut-off disconnects the output instead, restoring supply only when conditions return to safe. Your AC stops working for a few minutes; without it, your AC may stop working permanently. On a 2-ton machine, that's the most valuable feature here.
A digital display, and why it's more than a gadget
Most stabilizers are a sealed box with a lamp: you have no idea what your supply is doing or whether the unit is working. This one shows input voltage and output voltage live — and seeing both is genuinely useful. You learn what your building's supply actually does across a day, which tells you whether your area needs this at all. You can see the stabilizer working: input swinging, output holding steady. And if there's ever a complaint about AC performance, the display tells you immediately whether voltage is the cause — instead of guessing. Behind it, microcontroller-based sensing corrects faster and more precisely than older relay-only designs.
Sizing — and a note on inverter ACs
5 KVA is rated for one air conditioner up to 2 ton, and it's stated as suitable for both inverter and fixed-speed machines. One AC only — this isn't a whole-house unit, and adding a second appliance will overload it. What actually settles correct sizing is the AC's rated current, its compressor starting load, and the AC manufacturer's own recommendation. Worth knowing honestly: many recent inverter ACs are specified by their makers as needing no external stabilizer, because the voltage tolerance is built in. If yours is one of them, fitting this does no harm but may be unnecessary. Send us your AC's make, model and tonnage and we'll tell you either way.

🎯 Right for
For a 1.5-ton AC, our 4 KVA models cost less and are the correct rating — this 5 KVA unit is for 2-ton machines.
⚙️ At a glance
Copper conducts better than aluminium, so less energy is lost as heat — and heat is what ages a transformer. It's the specification worth asking about on any stabilizer you compare.
A 2-ton AC compressor replacement costs many times this, and repeated low-voltage starting is one of the things that kills them.
When the AC underperforms, the display tells you at a glance whether the supply is the cause — no electrician needed to find out.
Wall or floor. Wall mounting keeps it away from children and water and in free air, which extends its life.
Send us your AC's model and tonnage before ordering and we'll confirm this is the right rating.

Bluebird 5 KVA · BA 514C · Voltage Stabilizer for 2 Ton AC · 140–270 V Input · 100% Copper Winding · Digital Display · Microcontroller Control · High-Low Cut-Off · 2-Year Warranty
Warranty as per Bluebird's terms and conditions — 2 years manufacturer warranty, subject to T&C; coverage of the transformer winding, relay and control components, microcontroller and regulation circuit, display, cabinet, cables and accessories, parts and labour, exclusions, service type and the service process are subject to brand policy and the final invoice or warranty documentation. Regulation performance, supported input range, cut-off behaviour, display accuracy, electrical loss, heating and noise depend on incoming voltage, load current, compressor starting current, AC type and model, wiring condition, earthing, socket and MCB rating, ambient temperature, ventilation, installation quality and maintenance. The 5 KVA rating and suitability for one AC up to 2 ton are general compatibility guidance: verify the connected AC's rated current, maximum input, starting load and the AC manufacturer's own stabilizer recommendation before purchase and installation. Do not connect multiple appliances or an incompatible load. High-low cut-off reduces risk but does not guarantee protection in every fault condition; a voltage stabilizer manages fluctuation within its specified range and cannot protect against every surge, lightning strike, short circuit, wiring fault, neutral failure or voltage outside that range. Installation and electrical connection must be carried out by a qualified electrician with proper earthing, wiring, MCB protection and ventilation clearance. Do not cover the unit or install it near water, heat, direct sunlight or flammable materials.
