Description
A three-phase UPS with a capacity of 15–20 kVA provides high-quality, stable power for mission-critical facilities.
The cold start function allows the power supply to be turned on and connected equipment to be powered exclusively by batteries in the absence of an external 220V voltage. This ensures temporary operation of the equipment during a power outage.
