Product Description

200KVA Low Voltage Three Phase Dry Type Transformer 690V To 400V



1. Feature


A transformer is an electrical device that is used in AC power distribution systems to safely “step up” or “step down” voltages to meet the incoming power requirements of connected equipment. Transformers achieve this goal without modifying the frequency or amount of electrical power to help ensure connected devices can operate reliably.
