SchP02P, SchP72P, SchP96P, SchP120P

Meters are intended to measure and convert the effective value of current, voltage and frequency in one-phase and three-phase AC circuits into output unified DC signals and to transmit measured values through serial digital interface RS485, which allow using meters in automated systems of various purpose.
The meters have the possibility of programming with built-in buttons or through interface RS485:
– Indication range, position of decimal point;
– level of controlled input signals (settings);
– change in brightness of digital indicators illumination;
– interface parameters.
SchP120P meets the requirements of PJSC ROSSETI and PJSC FGC UES, they are recommended for the use at facilities of JSC ROSSETI and PJSC FGC UES.
