In industrial frequency converters/inverters, Hualian optocouplers play an indispensable role by their stable performance. Both high-speed optocouplers and gate driven optocouplers have brought significant advantages to industrial frequency converters/inverters.

High speed optocouplers are mainly used for signal transmission in industrial frequency converters/inverters. Due to high-speed transmission characteristic and common mode suppression ability, frequency converters/inverters can achieve high-precision and high-speed control effects. This greatly improves the operational efficiency of industrial equipments and meets various complex and high demand industrial application scenarios.

Gate drive optocouplers are mainly used in industrial frequency converters/inverters to drive IGBTs or MOSFETs. As efficient photoelectric conversion elements, gate driven optocouplers can convert weak electrical signals into strong electrical signals which are sufficient to drive IGBTs or MOSFETs. This greatly enhances the driving capability of the converters/inverters, ensuring the stable operation of industrial equipments.

High insulation voltage between input and output, fast switching speed, strong common mode suppression ability, wide operating range of power supply voltage (driving optocoupler), multiple packaging specifications/transmission speed/output current are available.
