The AVR has the faclity for droop CT connection,to allow parallel running with other similarly equipped generators.<br> SX440 is a two phase sensed Automatic Voltage Regulator(AVR) and forms part of the exciation system for a brush-less generator.<br> The AVR senses the voltage in the main generator winding and control the power fed to the stator and hance the main to maintain the generator output voltage within the specified limits, compensating for load sprrd,temperature and power factor of the generator.<br> Vibration:20 -100HZ (50mm/sec), 100Hz -2kHz<br> Colour: Black<br> Material: metal + PC<br> Sensing Input:<br> Voltage: 190-264V ac max, 1 phase 2 wire<br> Frequency: 50-60HZ nominal<br> Power inpot<br> Voltage: 140-220 V ac max, 3 phase,3 wire<br> Current: 3A/phase<br> Frequency: 100-120HZ nominal<br> Out put<br> Voltage: max 120V/DC<br> Current: continuous 2.7A/DC<br> Intermittent 6A for 10 secs<br> Resistance: 15 ohms minimum<br> Regulation: +/-1%<br> Thermal drift: 0.03% per .C change in AVR<br> Soft start pamp time: 3 sec<br> Typical system response<br> AVR respone: 10ms<br> Filed current to 90%: 80ms<br> Machine Volts to 97%: 300ms<br> External voltage adjustment: +/-10% with 1k ohm 1W trimmer<br> Under frequency protection<br> Set point: 95%HZ<br> Slope: 170% down to 30HZ<br> Unit power dissipation: 12 maximum<br> Analogue input<br> Maximum input: +/-5V/DC<br> Sensitivity 1V for 5% Generator Volts(adjustable)<br> Input resistance 1k ohm<br> Quadrature droop input<br> 10 ohms<br> Max.sensitivity:0.07A for 5% droop OPF<br> Max.input:0.33A<br> Over excitation protection<br> Set point:75V/DC<br> Time relay:10 sec<br> Environmental<br> Vibration:20 -100HZ (50mm/sec), 100Hz -2kHz<br> Operating temperature: -40C to +70 C<br> Relative Humidity: 95%<br> Storage temperature: -55Cto +80C<br> Package Contents: 1 x Automatic Voltage Regulator<br> Only the above package content, other products are not included.<br> Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
