Electricity meter PSCH-4TM.05
Used for commercial and technical forward and reverse recording of active and reactive electrical energy consumption in three-and four-wire AC circuits with voltage of 3x57. 7 / 100 V or 3*120-230 / 208-400 V, rated (maximum) current 1 (1. 5) A or 5 (7. 5) A and frequency 50Hz.
Meters are equipped with RS-485 interfaces and optical port and can be used as part of an automated registration system as well as part of a monitoring system. Meters support SET-4TM02 compatible protocol. Meters come in several modifications with various accuracy classes, rated voltage and current, presence of backup power unit.
