Regardless of the experiment and heating, the FDDG and FDSG series transformers need to be stepped down from the power supply voltage to rise.The low voltage current up to thousands or million amperes.The high voltage voltage of this series is generally 220 volts, 380 volts and 650 volts.Its low-voltage voltage is different by the magnitude of the rise, and it is a series.When using this series of products, it is generally necessary to add voltage regulation on the front side of the power supply.The low pressure side to achieve stepless adjustment.The transformer is suitable for continuous working, and the output voltage is safe voltage 3V, 6V, 9V, 12V, 15V, 24V, 36V, etc.(can be designed according to customer requirements).Applicable places are suitable for continuous load testing of electrical equipment, such as electroplating, smelting, textile motors, diamond industry, heating of current and current transformers,Circuit breakers, contactors, thermal relays, switches, etc.As a power source for temperature rise experiments, protection characteristics experiments, continuous load experiments, and electrical parameter measurement experiments.

Energy-saving low-noise: Stacked with high quality cold rolled silicon steel sheets;It is treated by special dipping process, which effectively       reduces vibration and noise during operation;And the use of high temperature insulation materials and design of new technology,The         introduction of new technologies makes transformers more energy efficient and quieter.The energy-saving low-noise coil has a ventilation slot, and the air flow is smooth, which effectively reduces the temperature of the coil.

High reliability: The structure is reasonable, the efficiency is high, the waveform is not distorted, the use is convenient and reliable, and it can run for a long time.The performance indicators are in full compliance with the GB/6450 dry power transformer standard requirements.

It can isolate the main power supply, shock, anti-interference and lightning protection.

Environmental protection characteristic ：It has heat resistance, moisture resistance, stability, chemical compatibility, low temperature, radiation resistance and non-toxicity.

Versatility:From a single transformer to a multi-functional combined transformer with cold air, protective casing, transformers, etc.
