Three Phase 30kVA Industrial Power Supply Voltage Stabilizer

Product Description

GRT-VFDC Features
GRT-VFDC series inverter voltage drop DC bus protection device is an efficient energy management system specially designed for inverter.It adopts advanced super capacitor technology, which can quickly compensate the DC bus voltage and prevent the inverter from shutting down in case of short-term utility power failure or voltage dips. The device has a built-in high-precision voltage monitoring circuit, which monitors the utility and DC bus voltage in real time to ensure the system's rapid response to voltage changes. The intelligent control system adopts advanced algorithms to ensure that the charging and discharging process of the supercapacitor is accurately controllable, avoiding over-discharging and charging and extending the service life of the device. Its functions also include status monitoring and alarm, data recording and analysis, and remote monitoring and management. This system not only has significant advantages in terms of stability, reliability and continuous operation performance of the inverter, but also reduces the maintenance cost and downtime of the system, and improves productivity and equipment utilization. Therefore, it has a wide range of application prospects in the field of industrial automation, and is an ideal choice for improving the stability and efficiency of production lines.
