The StromerPower 70kVA Three Phase Alternator (STRO-70K) is a commercial-grade, three-phase low-voltage AC alternator engineered within a strict ISO 9001 quality assurance environment to deliver uncompromising reliability. Designed as a premium component for stationary diesel generator sets, mobile power plants, and industrial equipment, this 4-pole brushless alternator features high efficiency, low reactances, and exceptional motor-starting capacity under heavy starting loads.

  • Dual-Rating Performance: Delivers 63kVA Prime power and up to 70kVA Standby power output at a stable 50Hz frequency (PF = 0.8).
  • Advanced Voltage Regulation: Features the industry-standard SX460 AVR model maintaining a tight +/- 1% voltage regulation to shield sensitive equipment from fluctuations.
  • Clean Power Winding: Implements a 2/3 pitch stator winding layout that cleanly suppresses lower-order harmonic distortion, keeping Total Harmonic Distortion (THD) under 5%.
  • Rugged Mechanical Interface: Built with a resilient single-bearing configuration optimised for native SAE housing flange and clutch flex plate alignment setups.
  • Industrial Grade Protection: Outfitted with an IP23 weather-protective enclosure, Class H insulation, robust steel base, and dynamically balanced rotors compliant with ISO 1940 vibration specifications.
SUPERIOR QUALITY AND PERFORMANCE

Our company sets new global standards in quality in all the aspects from design, manufacturing, material selection, production and testing equipment, tooling, and quality control.

GENERAL SPECIFICATIONS

StomerPower 70kVA Alternator

Scale up your standby generation infrastructure and protect your operations from municipal power failures with the StromerPower 70kVA Three Phase Alternator (Model: STRO-70K). Engineered explicitly for high-demand industrial installations, heavy workshops, and commercial complexes, this brushless synchronous power unit delivers great load-carrying capacity during severe load-shedding cycles. Running smoothly at a synchronised 1500rpm operating speed, the 4-pole self-excited design manages heat buildup efficiently while providing superior transient voltage recovery times.

Designed to maintain balanced multi-phase power across all three distribution lines, the STRO-70K delivers a rock-solid 63kVA prime power capacity. Sourcing this genuine StromerPower industrial unit ensures that your facility's automated fabrication cells, ducted cooling grids, large agricultural water pumps, and local data nodes remain completely live when primary power networks fail.

Precision Three-Phase Power Regulation and Harmonic Suppression Architecture

Featuring optimised, heavy-duty cooling fan chambers and tight production tolerances, this machine matches up cleanly with mid-to-large diesel engines without creating alignment deviations or high mechanical shaft wear. The thick structural steel base and high-purity copper windings give plant engineers a long-term, dependable asset built for continuous productivity under testing environmental loads.

StromerPower 70kVA Alternator Key Features

  • High Multi-Phase Capacity: Delivering a reliable 63.6kVA prime rating, this alternator easily manages unbalanced loads across busy commercial properties and light manufacturing facilities.
  • Refined Vibrational Baseline: Dynamically balanced rotor components comply with strict ISO vibration criteria, reducing overall machine wear inside soundproof canopy assemblies.
  • Optimised Copper Cores: Built using premium-grade copper stator windings to keep internal impedance low, helping to limit engine fuel burn during extended backup runs.
  • Rigid Structural Chassis: The heavy-gauge steel base frame prevents physical warping during logistics transport and stands up well to high-torque start-ups.
  • Precise Loop Regulation: Comes equipped with a responsive Automatic Voltage Regulator (AVR) to steady outbound currents and protect sensitive electronics from voltage sag.
  • Industrial Isolation Rating: Outfitted with Class H thermal insulation and an IP23 outer protective shell to keep production lines active in humid or dusty spaces.
  • Accessible Junction Design: An expanded top-mounted enclosure gives field technicians straightforward access for quick output terminations, checks, and AVR fine-tuning.
  • Harmonic Control Barrier: Supported by StromerPower's established engineering background, this low-reactance assembly limits distortion to maintain a clean, smooth electrical sine wave.
