Project Description

• Voltage adjustment rate < ±0.5%
• It is applicable to 220/380/440VAC brushless generator.
• Chosen by toggle switch: 50/60Hz
• Small, light and strong weather ability
• With the function of under-frequency protection and slow voltage build-up
• With EMI suppression circuit
• With function of high breaking capacity fuse protection

Detected input voltage: 220/380/440VAC, single-phase two-wire, chosen by toggle switch
– Frequency: 50/60Hz, chosen by toggle switch
– Power input voltage: 100~300VAC, single-phase two-wire
– Output voltage of magnetic field: max voltage 90VDC when input 240VAC
– Continuous current: 5A
– Discontinuous current: 7A within 10s
– Resistance: Min 12Ω,Max 100Ω
– Voltage adjustment rate: < ±0.5% (the engine speed changed within 4%)
– Voltage build-up when the residual magnetism voltage of AVR input terminal is above 5VAC
– Outside voltage adjustment rate: ±7% (used 1KΩ, 1Watt potentiometer)
