Product Description

Product introduction

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

· Designed for optimal performance at altitudes reaching up to 2000 meters, ensuring efficient operation in diverse environments.



· Operates efficiently within an ambient air temperature range of 40°C to -5°C. For environments exceeding 40°C or dropping below -5°C, specify your needs for a personalized, tailor-made solution at the time of order, ensuring adaptability to unique conditions.

· At a maximum temperature of 40°C, the relative humidity should not exceed 50%. However, at lower temperatures, a higher relative humidity is permissible, ensuring flexibility in various conditions and maintaining operational reliability.
· For instance, at 20°C, the product can handle up to 90% relative humidity. Special measures should be considered for occasional condensation due to any temperature fluctuations to preserve longevity and performance.

 

Ensure the surrounding air is free from harmful gases or dust that may corrode metal and damage insulation. The transformer should remain safeguarded against exposure to water, ensuring sustained functionality and prolonged service life.
· Protect against erosion caused by rain and snow, ensuring longevity and reliability of the product in various weather conditions.
