AVR - FC3 Operation Manual EGCON Co., Ltd
1. Introduction
AVR-FC3 is an automatic voltage regulator.
2. Feature
2.1. Available for low exciter field resistance.
2.2. Excited early. (When residual voltage is left)
2.3. Less trouble. (no relay and no transformer)
2.4. Durable under dust, damp and vibration. ( SILICON MOLDING )
2.5. ingle phase radio wave control using SCR
2.6. Available to get input power(220Vac50Hz/60Hz/125Hz) from PMG(permanent magnetic generator) or
assisting winding
2.7. Parallel operation is available.
2.8. From an external device, voltage control is available.
2.9. Available to get 220Vac or 380Vac sensing voltage
2.10. Protecting AVR and generator by controlling low frequency.
2.11. Over output voltage protector setting.
2.12. Stability setting switch for large and small capacity generator.
2.13. Substitute model for AVR126.
3. Specification
3.1. Maximum continuous output : 125Vdc, 10A(1250W)
3.2. Maximum output for 10secs (240Vac input) : 200Vdc, 15A(3KW)
3.3. Power input: Single phase 180-270Vac ±10%, 50/60/125 Hz, 1.2KVA
3.4. Sensing input: Single phase 180-270Vac, 300-450Vac, 50/60Hz. 8VA.
3.5. Exciter field resistance : 18.3-100Ω
3.6. External voltage control resistor : 2 K , 2 WΩ
3.7. Voltage build-up: raised by residual voltage(min 5 Vac) of the generator.
3.8. Voltage stability : Less than ±1% between no load to full load
3.9. Responding time : Within 1.5 cycles while ±5% sensing voltage changes.
3.10. Available for Brushless, 50 / 60 Hz generator.
3.11. Parallel input : 5Aac, 2VA, On factor 0.8, droop is adjustable to about 6%
3.12. Assistant input :±30% of Voltage can change by receiving ±3Vdc, 0.6mVA as a signal.
3.13. Low-frequency protection : Working at 47Hz when 50Hz, at 57Hz when 60Hz.
3.14. Over excitation protection: When exciter field voltage goes over 75-125Vdc, AVR stops outputting
for a while. After detecting over input voltage, it outputs for 10 secs. But delayed time is getting
shorter as voltage goes higher. When output goes over 240Vdc, AVR shut off output instantly.
3.15. Power consumption: max. 35W.
3.16. Fixing bolt: Smaller than M5.
3.17. Size: W150 H135 - D36(mm), Cut-outl: W130 H115(mm)
3.18. Weight; 0.9Kg, 1Kg(including box)
3.19. High current-limiting fuse: 250Vac, 6.3A. 5 -20L.Φ
