Product Description

Product introduction

Introducing the D-R series jack special transformer, a masterfully engineered marvel designed for AC circuit frequencies of 50Hz. This transformer stands out as an exceptional power supply solution for local lighting in machine tools and other equipment, meticulously crafted to align with the stringent Q/ZT 258 standards.
This expertly crafted transformer system harmonizes the esteemed NDK series transformer with a durable protective shell. The shell is ingeniously designed to feature terminals for smooth and seamless input power and load wiring, complemented by secure ground screws, ensuring impeccable grounding integrity and reliability.

· Engineered for peak performance at altitudes reaching up to 2000 meters, offering adaptability in diverse environments.



· This remarkable transformer operates with impeccable efficiency within an ambient air temperature spectrum of 40°C to -5°C. For environments where temperatures exceed 40°C or fall below -5°C, we offer bespoke, tailor-made solutions upon request, ensuring precise accommodation of your specific needs.

· At a peak temperature of 40°C, the relative humidity should stay under 50%. However, at cooler temperatures, the allowance for higher relative humidity introduces flexibility, making this transformer adaptable to a variety of environmental conditions.
· For example, at 20°C, the transformer can adeptly manage up to 90% relative humidity. It is advisable to consider special precautions to address potential condensation resulting from any temperature variations.

 

Ensure the surrounding atmosphere is devoid of harmful gases or dust that can corrode metal and compromise insulation. The transformer must be shielded from water exposure, safeguarding its continued functionality and performance.
· Take protective measures to prevent damage from rain and snow, ensuring the transformer's longevity, reliability, and sustained operational excellence.

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
