UPS input (output) isolation transformer

The UPS input (output) isolation transformer not only has the function of transforming transformers in the power grid, but also can isolate the third harmonic of the power grid from equipment. The primary and secondary are shielded with copper foil, effectively protecting the interference of power grid harmonics on equipment. When the zero ground voltage is required to be zero, it can be short circuited to zero ground to better suppress power grid harmonics.

The specifications range from 1KVA to 1800KVA, suitable for various three-phase power supply scenarios with AC 50-60HZ and input and output voltages not exceeding 1600V. The input and output voltage (three-phase or multiple input and output, etc.), connection method, tap position adjustment, winding capacity allocation, secondary winding configuration, and outer box (selected according to different usage environments) of the product can all be carefully designed and manufactured according to user requirements.

Product advantages:
1. High quality brand new cold-rolled oriented silicon steel sheets are stacked together; H-grade heat-resistant 180 ° enameled wire, with beautiful and elegant bare coil winding, primary and secondary air duct fan for fast heating, galvanized tripod, treated with special dipping process, vacuum dipping, oven drying! The introduction of new processes and technologies, such as effectively reducing vibration and noise during operation, increasing electrical strength, and using high-temperature resistant insulation materials, has made transformers more energy-efficient and quieter. The energy-saving and low-noise coil is equipped with ventilation slots, ensuring smooth air flow and quickly and effectively reducing coil temperature.
