Introduction

VR6 AVR are contained in an encapsulated plastic case, and regulator controls the DC exciter field power of conventional, 50 OR60 HZ 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. Which 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 includes 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 threephase

 

shunt, or permanent magnet power input, and parallel droop

 

compensation, and an accessory input. The accessory input provides

 

compatibility with accessories such as a var/power factor controller.

 

1.AVR VR6 is our new design specially for generator.

 

2. Thermal stability: Less than 0.5% per 40* amblent temperature change

 

3. AC input power:100 to 280 VA, single-phase 50  to 400 Hz, or 63 to 105 VA; three phase , 50 to 400 Hz, 1092 VA maximum continuous burden AC sensing voltage: 90 to 140 VA, 50/60 Hz; single- or three-phase. 

 

4. Regulator response: Less than 4 milliseconds
