Three-Phase Power Transducers – APT Series – NK Technologies

Description click to view larger image APT Power Transducers measure three phases of current and voltage, and produces an industry-standard analog signal proportional to the watts used. The monitor uses current transformers to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC. The APT power transducer can be configured to accept 5A secondary current transformers or the safer ProteCT™ low voltage output sensors. Either type of current sensing will produce an accurate output signal to help you identify areas of excessive energy consumption and allow intervention to reduce demand. APT Power Transducers produce full range output when the current transformer is producing its maximum signal, the primary voltage is at the range maximum and power factor is at unity.  Direct connect to 120–600 V  Works with 5 A or 333 mV CTs  4-20 mA, 5 V & 10 V outputs  Externally powered  DIN rail or panel mount  5 year warranty Catalog Page 101a            APT-Datasheet Downloads APT Manual ( PDF, 115.5KB )
