Description

KSTAR YDC3320S 20KVA/240V

YDC3300 series UPS is a three-phase in and three-phase out high-frequency UPS with medium and large power capacity.

Benefits from the high-efficiency transformerless double conversion technology, YDC3300(10-40kVA) can achieve 96% efficiency and high PF 1.0 thereby reducing the power and cooling costs.

It is designed to provide strict voltage regulation, frequency regulation, and zero transfer time to the battery during a power failure, making it ideal for small and medium data centres and other critical business applications.
