IBZDPS-T-3KVA transformer
Product Overview
This 3KVA transformer is designed specifically for water-cooled welding equipment, providing voltage conversion from 380V to 1.5V. It utilizes a Class F insulation system (withstands temperatures up to 155°C) and has passed the 3800V withstand voltage test (leakage current ≤ 0.5mA). It features an integrated thermal protection unit (operation threshold 85°C) and a water circulation cooling system (flow rate 8L/min, interface size ZG1/4). It meets the 50% duty cycle requirement of the EN 50504 standard and is suitable for high-intensity welding conditions.
