Product Description

Product introduction

The D-R series jack special transformer is meticulously engineered for AC circuit frequency of 50Hz. It serves as an exceptional local lighting power supply for machine tools and various equipment, adhering strictly to the Q/ZT 258 standards.
Expertly crafted, this transformer system combines the renowned NDK series transformer with a robust protective shell. The shell is thoughtfully designed with terminals for seamless input power and load wiring, alongside secure ground screws for optimal grounding integrity.

· Designed for optimal performance at altitudes up to 2000 meters, ensuring reliability in varied terrains.



· Operates efficiently within an impressive ambient air temperature range of 40°C to -5°C. For environments exceeding this range, specify your needs at the time of order for a bespoke, tailor-made solution that meets your precise requirements.

· At a maximum ambient temperature of 40°C, the relative humidity should not exceed 50%. However, flexibility is retained at lower temperatures, permitting higher humidity, ensuring adaptability across diverse conditions.
· For instance, at 20°C, this product can handle up to 90% relative humidity. Consider special measures for occasional condensation due to temperature fluctuations to maintain its pristine condition.

 

Ensure the surrounding air remains free from harmful gases or dust that may corrode metal and damage insulation. Safeguarding the transformer against exposure to water ensures its sustained functionality and longevity.
· Protect against erosion caused by rain and snow, ensuring prolonged longevity and unwavering reliability.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 2000m
The waveform of the power supply voltage	similar to a sine wave
