Product Description



Introducing the D-R Series Jack Special Transformer, meticulously engineered for AC circuits with a frequency of 50Hz. This specialized transformer serves as a robust local lighting power supply specifically designed for machine tools and similar equipment. Fully compliant with the standard: Q/ZT 258, it guarantees reliability and efficiency in every application.
The D-R Series Transformer is innovatively crafted, comprising the advanced NDK series transformer encased in a durable protective shell. The shell is thoughtfully designed with terminals for seamless input power and load wiring, along with sturdy ground screws to ensure secure grounding.

·Designed for optimal performance, the transformer is suitable for use at altitudes not exceeding 2000 meters.
·Engineered to withstand a diverse range of temperatures, the upper ambient limit is 40°C, while the lower limit is -5°C. For environments exceeding these parameters, bespoke customization is available upon request, ensuring tailor-made solutions for every unique need.

·Under maximum ambient conditions of 40°C, the air's relative humidity does not surpass 50%. However, at reduced temperatures, a higher humidity level is permissible, accommodating more diverse climatic conditions.
·For instance, at 20°C, an impressive 90% relative humidity is viable. In cases of occasional condensation due to temperature fluctuations, we recommend implementing protective measures to maintain integrity.

The ambient environment must be free from corrosive gases or dust that can damage metal or compromise insulation. The transformer is built to withstand operational challenges but must not be exposed to water,
nor be subjected to rain and snow erosion, ensuring longevity and durability.
