Product Description

Product introduction

The D-R series jack special transformer is meticulously engineered for an AC circuit frequency of 50Hz, making it an unrivaled choice as a local lighting power supply for machine tools and various equipment. It strictly adheres to the Q/ZT 258 standards, ensuring high performance and reliability.
Expertly crafted for durability and efficiency, this transformer system is a masterful combination of the renowned NDK series transformer, housed within a robust protective shell. The shell is thoughtfully equipped with terminals for seamless input power and load wiring, complemented by secure ground screws that guarantee optimal grounding integrity. This design ensures both safety and ease of use.

· Engineered for optimal performance even at altitudes reaching up to 2000 meters, assuring reliable functionality across varied terrains.



· Operates with remarkable efficiency within a wide ambient air temperature range from 40°C to -5°C. For conditions exceeding 40°C or dropping below -5°C, our tailored solutions are available to meet your specific needs at the time of order, ensuring that unique operational environments are no barrier to performance.

· At a peak temperature of 40°C, the relative humidity should not surpass 50%. However, the design allows for higher humidity at lower temperatures, providing adaptability across diverse environmental conditions.
· For example, at a comfortable 20°C, the product can manage up to 90% relative humidity, accommodating various climatic conditions. Special precautions should be taken to mitigate occasional condensation due to temperature variations, ensuring continuous performance.

 

Ensure the surrounding air is devoid of harmful gases or dust that could corrode metal parts and damage insulation. The transformer must be shielded from water exposure, preserving its functionality and longevity.
· Protect the equipment against damage from rain and snow to guarantee its longevity and reliability, ensuring continuous operation in diverse weather conditions.

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
