About This Product

■Features

1, Realization of miniaturization By adopting a transformerless system and rational design, it can be significantly reduced in size and weight. A bypass circuit is included as standard for maintenance. 2.Improved overcurrent capability A static switch with high overcurrent capability is used as the direct feed switch, achieving an overcurrent capability of 150% of the rated current for 1 minute and 600% of the rated current for 1 cycle. Even in the unlikely event that a device failure occurs, the direct power switch will remain switched on (on) and continue transmitting power to the load. 3. Uninterrupted switching For example, when a voltage drop occurs on the power supply side and lasts for 230ms, the load side maintains a constant voltage. Additionally, there is almost no output voltage fluctuation immediately after an instantaneous voltage sag occurs, allowing a smooth transition to compensation operation. Therefore, it can be used with confidence in high-tech equipment. 4.Supports instantaneous interruptions During compensation, the switch is turned off and the bidirectional converter supplies the full voltage to the load. Since this is a parallel method, even if the power supply side is momentarily interrupted (open), it can be compensated for (not possible with a series method). In the standard specifications, compensation can be made for approximately 1 second at 100% load factor, approximately 3 seconds at 70% load rate, and approximately 5 seconds at 50% load factor regardless of the voltage drop rate. 5. Compatible with regenerative loads If regenerated power is generated from the load side during instantaneous sag compensation, compensation can be continued by charging the regenerated power into the capacitor. 6. Reduced running costs Since there is no need to replace the battery for about 10 years and it is maintenance free, running costs can be significantly reduced compared to UPS. There are other product numbers as well.
