The Rish CON-P programmable transducer series measure and convert active, reactive and apparent power of a single-phase or three-phase AC system with balanced or unbalanced loads. The output signal is proportional to the measured value of the active or reactive power and is either load-independent DC Voltage or DC Current output signal. The CON-P transducer is field programmable and/or data can be retrieved via optional 7 segment LCD display with backlit keypad or connecting a PC with RS232 interface and PRKAB601 adapter connected to the CON-P’s front panel programming connector, or simply networked via the RS485 port.
