Applications for DC Transducers and DC Switches
Many catastrophes can be avoided by using current sensors to monitor critical loads. When loads are powered by DC current it becomes more of a challenge than monitoring AC current. By far the simplest and most accurate method is to use an NK Technologies DT or DS series current sensor. This Hall-based non-contact design requires no cutting or terminating of the conductor. Just pass the lead through the sensor, or snap the sensor in place over the lead, and the sensor is ready to go. DT transducers produce a signal to the control system proportional to the current in the conductor, and the DS switches provide a contact, solid-state or electromechanical relay, which changes state at an adjustable current level.
NK Technologies can provide a cost effective method to monitor DC powered loads. Compare features with competitive methods; we hope your choice will be the most accurate, reliable and responsive current sensing products available.
