Automatic voltage controllers (servo voltage stabilizers), APFC panels and isolation transformers manufactured in Solapur, Maharashtra for Indian factories. Stabilize voltage, protect equipment and assess power-saving opportunities using your electricity bill.
Trusted by factories & industrial groups across India
Active Power Control is an industrial manufacturer of voltage stabilisation, power conditioning and electrical distribution equipment. We work with factories, plants and commercial facilities to design systems that protect critical loads, optimise energy use and extend equipment life.
Every product is engineered, assembled and tested in-house — and backed by a service team that understands real-world plant conditions, not just specifications.
Deliver dependable, energy-efficient power systems that reduce downtime and operational cost for Indian manufacturers.
Be the most trusted engineering partner for power quality and protection across industrial India.
Built to recognised industrial benchmarks with rigorous in-house testing on every unit.
Engineered for measurable energy savings, lower losses and faster payback on plant operations.
Premium core, copper and enclosure quality designed for years of continuous industrial use.
Pan-India service network with rapid response, on-site diagnostics and consultative engineering.
Six product categories engineered for stable voltage, equipment protection and efficient power conversion across plant operations.
A side-by-side view of ratings, voltage class, primary function and best-fit use-cases across our four most-specified categories.
Every APC unit is built around four engineering pillars — core, copper, enclosure and regulation. Together they deliver the reliability factories expect.
Cores are built from prime grade CRGO (cold-rolled grain-oriented) silicon steel laminations to minimise no-load losses and audible noise. Step-lap mitred joints and precise stacking ensure low magnetising current and stable flux distribution across the operating range.
Three of many — real APC installations with quantified energy, uptime and payback outcomes.
Chronic 438 V incoming supply was driving spindle drives into over-voltage trips. APC's 300 kVA servo AVC clamped output to 415 V, eliminating trips and cutting no-load losses.
Multiple LT stabilisers were replaced by a single HT AVR on the 33 kV incomer — regulating the entire plant upstream of six distribution transformers.
Common-mode noise was crashing PLCs on a granulation line. A shielded isolation transformer plus a detuned APFC panel eliminated trips and killed the PF penalty.
Enter your equipment's target voltage and pick your typical supply voltage range. We'll estimate equipment stress, the dominant loss type and the savings opportunity from voltage stabilisation.
Standard nominal: 415 V
Auto-filled from region & supply. Override if your plant uses a different baseline.
Use left and right arrow keys to adjust by 0.5%. Page Up and Page Down jump larger steps. Home sets −12%, End sets +12%.
Operating near your target voltage — minimal stress on motors and electronics.
At 0.0% deviation from your 415 V optimum, motors operate outside their efficiency curve. Expected avoidable loss sits at 1–2% of the energy bill, before counting downtime and maintenance.
A servo-controlled AVC clamps the output to the 415 V band continuously, so motors run at rated efficiency and electronics see clean voltage — recovering most of the avoidable loss.
Voltage profile is healthy. We still recommend a 7-day logged study to capture transient events and confirm.
Indicative range. APC engineering will validate with on-site voltage logging before any sizing recommendation.
Every system is sized and configured to your plant's load profile and SLD — no off-the-shelf compromise.
In-house fabrication, winding and assembly with documented quality control on every unit.
Voltage logging, audit and load study before we recommend a system — no over-selling.
On-site supervision, commissioning and operator handover by APC engineers.
Pan-India service network with rapid response and stocked spares for every product range.
Documented savings, payback projections and post-installation performance reporting.
Reference material for plant engineers, procurement teams and consulting electrical engineers.
Answers to what plant engineers and procurement teams ask us most often.
Share your plant details and our engineers will respond with a sized recommendation, indicative pricing and a payback estimate.
Share a few plant parameters. The tool will validate them, estimate avoidable loss and explain how each input affects the recommendation.
Baselines follow Global Standard (IEC 60038) — adjust min/max below to match your site readings.
Voltage and reliability issues are causing significant avoidable loss. A correctly sized AVC will recover most of it within an industrial payback window.
Loss % is derived from worst voltage deviation from your 400 V optimum, plus penalties for swing, trips, DG dependency and process impact (see bullets above).
Indicative figures only. APC engineering will validate with on-site logging and a load study before final sizing.
