Prostar GT500K 3 phase uninterruptible power supply ups 500kva

Provides reliable power protection and advanced technology for high power applications.

SKU: GT500K Category:

Prostar GT500K 3 phase uninterruptible power supply ups 500kva meets the unique requirements of medium to large data centers, industry, buildings, and mission-critical environments. This UPS includes ECO Mode, with cost-saving energy efficiency, and SPoT operation mode, which increases on-site test capability without additional load bank.

Uranus Series Low Frequency Online UPS includes 3-phase ins and 3-phase outs from GT6K-GT500K, which can be in parallel with 8 units UPS directly, conveniently and fast. flexible parallel technology could be applied to different loads and systems. According to the needs of customers’ constitute, it could make N+1 or N+X construction, but also according to the different needs of customers with different capacity, it could be in parallel with random 8 units UPS, and all the load will be loaded by all 8 units UPS averagely of the parallel redundant UPS system. Any UPS of the parallel redundant system was failed, the UPS will share its load immediately, to ensure system running normally. During the process of the parallel UPS, it does not set the host and the standby one, but was selected by customers flexibly. The first turned on UPS is automatically set to the host, when the host system failed, the host identity immediately transferred to another UPS, thereby ensuring the supply of electricity for clients during the using process, so it could become a true uninterruptible power supply.

Online Mode

During normal operation, Prostar ups 500kva will provide precise regulated and transient-free power to the critical applications. The mains supply provides power to the rectifier/charger.

The rectifier/charger will provide regulated DC power to support the inverter and simultaneously maintain the battery in a fully chargeed condition.

The inverter will convert the DC power into regulated AC power for the load.

Battery Mode

Upon failure of the mains supply, input power for the inverter will automatically be supplied from the directly connected battery. When the mains is restored or the standby generator set supply is ready, input power for the inverter and for recharging the battery will automatically be supplied from the rectifier/charger.

If the input does not return, the UPS 500kva will automatically shut itself down in an orderly manner when the discharge limit of the battery is reached.

Bypass Mode

Upon the failure of static inverter, the no-break static transfer switch will be activated automatically to isolate the faulty inverter and at the same time maintain a continuous supply to the system load. The automatic transfer mode will also operate in the event of system overloading or if irregular or undesirable output for the load is detected. In this case, the system would automatically return to the original mode of operation if the disturbance is cleared.

Manual Bypass Mode

If the UPS system needs to be isolated for testing or removed from service for maintenance, the maintenance bypass will transfer the loads from inverter to the mains without interruption and vice versa.
