The StromerPower 28kVA Single Phase Alternator (STRO-22K) is a commercial-grade, single-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 25.5kVA Prime power and up to 28kVA Standby power output at a stable 50Hz frequency (PF = 1).
  • 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 28kVA Alternator

Drive your custom power generation projects forward with the StromerPower 28kVA Single Phase Alternator (Model: STRO-22K). Built specifically to endure the extreme operational stresses of frequent utility disruptions, this heavy-duty brushless synchronous component functions as a durable powerhouse for industrial machinery setups, regional infrastructure links, and large rural properties. Running at a steady 1500rpm operating speed, the 4-pole self-excited system controls transient thermal buildup effectively while ensuring immediate voltage recovery during large power spikes.

Tailored for heavy single-phase operations, commercial business complexes, and demanding processing plants, the STRO-22K delivers a highly stable 25.5kVA prime power capacity. Selecting this premium StromerPower trade component ensures that your distribution boards, continuous refrigeration systems, local data server racks, and agricultural pump systems receive smooth, dependable electrical currents whenever the municipal grid cuts out.

Integrated Automatic Voltage Regulation and Harmonic Control

Featuring balanced airflow cooling paths and superior heavy-load stability, this unit integrates seamlessly into existing plant enclosures without creating excessive structural strain or unexpected technical downtime. Its heavy-gauge frame construction and proven copper-winding technology offer an excellent, long-term asset investment for facility managers aiming for true operational peace of mind.

StromerPower 28kVA Alternator Key Features

  • Durable Electrical Output: Providing a continuous 25.5kVA prime capacity, this component easily manages medium-to-large single-phase installations for farms, estates, or commercial units.
  • Smooth Mechanical Operation: Designed with tight manufacturing tolerances and high-grade internal balances, the unit minimises vibrational noise to fit quietly within soundproof generator canopies.
  • Conversion Efficiency: Built with high-purity copper windings to maximise mechanical-to-electrical conversion, directly lowering engine fuel consumption rates during extended runs.
  • Compact Footprint: The rigid steel base frame delivers extreme environmental durability while keeping a highly compact frame footprint for streamlined integration.
  • Smart AVR Monitoring: Factory-fitted with an Automatic Voltage Regulator (AVR) module to maintain steady line output and safeguard delicate electronics from spikes.
  • Environmental Safety Isolation: Protected by premier H-class thermal insulation layers and an IP23 housing shell to ensure continuous production in hot, humid, or dusty working spaces.
  • Spacious Junction Box: Features an expanded top-mount terminal terminal box that gives technicians easy access for quick wiring links, maintenance, or AVR tuning.
  • Validated Performance: Backed by StromerPower's established industry reputation, this low-reactance alternator ensures exceptionally clean electrical sine waves across complex commercial applications.
