Product Description

Product introduction

Introducing the D-R series jack special transformer, a marvel of precision engineering designed for AC circuit frequencies of 50Hz. This transformer stands out as a superior choice for local lighting power supply needs across machine tools and various equipment. It strictly conforms to the Q/ZT 258 standards, ensuring reliability and superior performance.
Expertly crafted with excellence, this transformer system ingeniously integrates the highly acclaimed NDK series transformer with a robust protective shell. The shell features thoughtfully positioned terminals that ensure seamless input power and load wiring, while secure ground screws enhance grounding integrity for optimal safety.

· Crafted for peak performance at impressive altitudes of up to 2000 meters.



· Operates with unparalleled efficiency within an ambient air temperature range of 40°C to -5°C. For environments surpassing 40°C or dropping below -5°C, please specify your requirements for a bespoke, tailor-made solution at the time of order.

· At a peak temperature of 40°C, the relative humidity should remain below 50%. However, at cooler temperatures, greater relative humidity is allowed, ensuring versatile functionality across varying conditions.
· For instance, at 20°C, the system can accommodate up to 90% relative humidity. Special considerations should be taken to address occasional condensation due to any temperature variations.

 

Ensure that the surrounding air is devoid of harmful gases or dust that could corrode metal or damage insulation. The transformer must be protected to prevent exposure to water, thereby ensuring its long-lasting functionality and durability.
· Safeguard against any erosion caused by rain and snow, thereby ensuring the product's longevity and reliable performance.
