Description
Maxgeek EA15A-2 Generator AVR Automatic Voltage Regulator Voltage Stabilizer Board for Brushless Generator
Specification:
Sensing Input: 220/380/440VAC, 1 phase 2 wire
Frequency: 50-60Hz nominal
Voltage Input: 100-300VAC, max 90VDC at 240VAC input
Current: continuous 5A, intermittent 20A for 10 secs
Resistance: 15Ω minimum
Regulation: +/-0.5% with 4% engine governing
Voltage Build Up: residual volts at AVR terminal ï¼5VAC
External Voltage Adjustment: +/-15% with 5k ohm 1 watt trimmer
Frequency Roll-off Adjustment:
-Connect a jumper from COM to the 50HZ terminal for 50HZ operation, or leave the two terminal unconnected for 60Hz operation.
-To reset the frequency roll-off, proceed as follow:
1. Startup engine and build voltage;
2. Adjust the prime mover RPM to the desired frequency compensation (corner frequency roll-off) point;
3. Adjust the front panel FREQ control until the output voltage low about 5V than nominal voltage (For 50HZ applications, the frequency "roll-off" is factory preset to 45Hz, for 60Hz operation, the frequency is 55Hz).
Voltage Adjustment:
1. Adjust the front panel VOLT to vary the generator nominal voltage.
2. If used, a 500Ω 1watt potentiometer may be connected to terminals VR and VR, refer to Figure 4, 5.
Stability Adjustment:
1. Adjust the front panel STAB control the system stable.
2. Rotation of the front panel STAB control in the counter-clockwise (CCW) direction will speed response time If rotated too for CCW, the generator voltage my oscillate (hunt).
3. Rotated the front panel STAB control CCW until the system start oscillating and then rotate cw just past the point where oscillation occurred.
Droop Adjustment:
The droop adjustment allows for adjustment of the amount of droop which will occur in the generator output voltage for a given amount of reactive load current. A CT should be selected which will supply the A.V.R with 3 to 5 amperes of current with rated load and power factor on the generator. With 5 Amps of current supplied by the CT, at 0.8 power factor, the amount of droop can be adjusted from 0 to 6% of nominal generator voltage.
