General
PM series digital display AC ammeter can be used to measure distribution system's single or three-phase current. The ammeter's transformer ratio can be programmed. It supports switch volume input, electric relay output, analog output and communication functions (Modbus-RTU Communication Protocol). There are also different installation sizes. It can replace analog pointer ammeters.
