P12P - Programmable Transducer 1-Phase | Energy Meter | Power Analyser

P12P type Programmable transducer is designed to convert single-phase network parameters: a.c. voltage and a.c. current, frequency, active, reactive and apparent power, power factor cosj, active power to reactive power ratio, phase shift angle,active, reactive and apparent energy into a digital or standard current or voltage signal. 

The output is galvanically isolated from the input and supply. The insulation exists also between the current and voltage input. The P12P type transducer has programmable measuring and auxiliary functions. The parameter modification is possible through the PD14 programmer, the RS-485 interface or from the keyboard. The transducer is commonly used in computer systems, e.g. with LUMEL-ENERGY program.
P12P type transducer has a programmable auxiliary function:
Conversion of measuring value into an output signal on the base of the individual linear characteristic
Recalculation on the input quantity into any indication on the base of the individual linear characteristic
Programming of alarm outputs
Signalling of the measuring range exceeding
Recording of any input signal in programmed segments of time or event recording,
Programming of the indication resolution
Preview of all measuring values and set parameter values
Programming of voltage and current ratio
Zeroing of energy counters
Storage of all counter states in case in case of a decay of the supply voltage
Automatic setting of the decimal point
Storage of maximal and minimal values of all input quantities
Programming of the time and kind of measurement averaging: arithmetic mean, walking window
Display of the unit
Service of the RS-485 interface in the MODBUS protocol, both in ASCII either in RTU mode
Data protection by means of a password.
