March 4, 2020 – NK Technologies released its 2020 product catalog, featuring performance data, sizes, specifications, and technical references for the company’s portfolio of current sensing switches, transducers, transformers, and ground fault protection products. The catalog includes recently-introduced products such as:
- DT-BB DC current transducer: Allows a split-core transducer to be installed over existing bus bars or wire.
- AG-LC ground fault sensor: Helps meet NEC ground fault protection requirement for the main overcurrent device feeding marinas and boat yards.
It can be mounted on a panel or DIN rail, and is rated to measure DC current with working voltage to 1500 VDC.
The design puts the current sensing components in one housing with the signal conditioning.
These services often carry up to 800 amps; most sensor designs will not allow the conductors to pass through a single sensing ring.
By designing a sensor in a large solid-core housing, the conductors will not have to be passed through a separate sensing device like a zero-sequence current transformer.
