2. Product core advantages: The foundation of the leading position in the industry.


2.1 Installation without power outage


DP series is a kind of advanced open type current transformer, adopting a split clamp structure. The design will enable engineers to attach the existing equipment easily onto busbars or cables without affecting the operation of them and greatly improve the installation efficiency. It is suitable for the places where high power continuity should be ensured, such as data centers, production lines, and commercial buildings.


2.2 High precision output, stable and reliable signal


It can linearly convert high current signals at the primary side to standard 4-20mA DC analog signals. Its accuracy stays at a high level of ±1.5% over the whole measurement range. This stable and reliable output signal can be directly connected to PLC, DCS, or energy management systems, so that an accurate and error-free data foundation can be guaranteed for automation control and energy assessment.


2.3 Wide range of models and comprehensive range coverage


To satisfy different applications, our company offers a full range of DP series models: DP-58, DP-88, DP-812, DP-816, etc. in the measuring range covering 0 to 5000A. The full product layout will make sure that customers can find the most suitable open-type current transformer model for any given level of current monitoring.
