omron inverter repair, Shenyang on people (certified), a large stone bridge inverter maintenance provided by the Shenyang Electric Co., the people. Shenyang on China Electric Co. (www.zsmsy.com) is specialized in the "high-low-voltage inverter, high and low voltage soft starter, magnetic switches, programmable logic controller (PLC)" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Wei Song. Use drive repair electrolytic capacitors note 1, electrolytic capacitors have polarity inverter due to maintenance, and therefore can not be reversed in the circuit connection use. In the power supply circuit, the output voltage is positive then the positive power output of electrolytic capacitors, negative ground, the output voltage is negative then the negative output terminal, positive ground. When the power supply filter capacitor circuit in reverse polarity, because of the filtering effect of greatly reduced capacitance, while causing the power supply output voltage fluctuation, on the other hand because of the reverse energized to make this point is equivalent to a heat resistance of the electrolytic capacitor. When the reverse voltage exceeds a certain value omron inverter repair, reverse leakage resistance and capacitance will become very small, so energized to work soon, so that the capacitor can overheat and burst damage. 2. Applied to both ends of the electrolytic capacitor voltage can not exceed the allowable operating voltage, in the actual circuit design should leave a margin depending on the circumstances, the transformation of the sensor in the design of imported power supply filter capacitor, if the AC voltage is 220 ~ rectifier transformer secondary voltage up to 22V atv61 drive repair, then select 25V voltage electrolytic capacitors generally meet the requirements. However, if the AC power supply voltage fluctuations are large and there is likely to rise to more than 250V, the best choice for the electrolytic capacitor voltage above 30V. 3, electrolytic capacitors in the circuit should be close to power the heating element to prevent the acceleration due to heat leaving dry electrolyte. 4, for positive and negative polarity signal filtering, can take two electrolytic capacitors in series with the polar method, as a non-polar capacitor.
