Key Product Advantages
Stable Voltage Regulation Performance
Built with ±2×2.5% tapping adjustment range on primary side, staff can manually adjust tapping position according to actual onsite grid voltage changes. It efficiently stabilizes output voltage, avoids equipment damage caused by overvoltage or undervoltage, ensures all electric devices operate within safe voltage scope.
High-Efficiency ONAN Cooling System
Natural oil circulation combines with natural air heat dissipation, no extra fan cooling device required. The cooling structure is simple and failure-free, effectively dissipates operating heat generated during long-time full-load operation, maintains stable internal temperature, lowers daily maintenance cost and energy consumption.
