Three-phase current and voltage table offer a combination of AC and DC current and voltage table Shanghai factory quality assurance instrument manufacturers high imitation brand PD194 series of DC current and voltage combinations table summarizes: direct current voltage combinations table can directly replace conventional measuring instruments. As an advanced intelligent front-end digital capture devices, the power meter has been widely used in various control systems, SCADA systems and energy management systems. Features: The instrument can have a RS-485 communication interface, using Modbus-RTU protocol; available with analog output, relay alarm output, digital input / output. Depending on the requirements, through the instrument panel buttons on the transformation ratio, alarms, communications, digital output setting and control. Features: Measurements: Three-phase voltage, phase current displays three rows: LED digital display, highly visible communication: RS485 communication, MODBUS-RTU protocol Input: Road switch input and output: switch output Road Expansion: programmable set of input parameters changed directly from current and voltage transformer signal, than the use of the site can be widely used in substation automation, distribution automation, intelligent building, internal energy measurement, management and evaluation
