Three phase 300 kVA isolation transformer offers consistent, smooth voltage transformation at 480V AC input, 480V to 400V version or 400V to 480V is available, and other voltages can be customized.
Generally, isolation transformers with power above 150KVA will be equipped with an alarm, which is used to detect the temperature of the transformer. When the temperature of the transformer rises to 150 degrees, the alarm will be triggered. At this time, the transformer needs to be manually suspended or stopped. Wait until the transformer temperature returns to normal, then continue to use.

Tips: Using isolation transformer to reduce the zero voltage of UPS
For medium and small power UPS, generally, an isolation transformer is installed at its output part; for a three-in to three-out high-power UPS, the transformer is usually at its bypass input. This method can eliminate the problem that zero voltage is low before the UPS powering on while zero voltage rises after UPS turning on. The UPS power system makes no negative impact on the power grid and load through this method.
