General description

The K65-12B and K125-10B Voltage Regulator are contained in an encapsulated plastic case. The regulator controls the DC exciter field power conventional, 50 or 60Hz brushless generators.

Regulation is provided by sensing the generator output voltage, converting it to a DC signal, and comparing the signal to a reference voltage signal. An error signal is developed and used to control the DC field power in order to maintain a constant generator output.

The regulator included frequency compensation with selectable slope, inverse time over-excitation shutdown, solid-state build-up circuitry, single-phase or three-phase voltage sensing, single-phase or three-phase shunt, or permanent magnet power input, and parallel droop compensation, and an accessory input. The accessory input provides compatibility with accessories such as the var/power factor controller.

Technical Specifications

  • Regulation Less than ±1% no load to full load
  • Regulator drift Less than ±1⁄2% steady-state
  • Temperature drift Less than ±1% for any 40° C change over the operating temperature range
  • Regulator response Less than 4 milliseconds
  • Regulator sensing Three phase or single phase available on SE and PM generators
  • Regulator stability
  • The regulator responds to the fundamental component of the sensed voltage and remains stable for total harmonic distortion of the generator output voltage waveform up to 20%.
  • Regulator filtering Telephone Influence Factor (TIF) less than 50.
  • Optional filtering packages available to comply with MIL-STD 461B Part 9 and VDE 85 level N.
  • Harmonic tolerance The AVR will maintain precise control of the generator output with up to 20% harmonic distortion in the generator output voltage.
  • The voltage adjust range –25% to 10% of nominal
  • Regulator build-up voltage Regulator will build up with the generator output voltage as low as 6 VAC when used with SE generators. No minimum requirement when used with PM generators.
  • Regulator start-up voltage Voltage overshoot at full throttle engine starting will not exceed 5% of rated value.
  • Frequency compensation Voltage is linearly proportional to frequency for 8 Volts/Hz or 16 Volts/Hz below-knee frequency. Knee frequency is adjustable from 45 Hz to 65 Hz. This provides matched engine/generator performance for improved block load performance.
  • Reactive droop adjustment Adjustable from 0% to 10% at rated input current (1A or 5A)
