Functions & Features
• Measures simultaneously several variables of a heavy-current power system: current, voltage, active, reactive and apparent power, active and reactive energy, power factor, frequency, etc.
• All measured values, counter values, display mode, setting data are stored in the non-volatile memory at the power off
• Parameters are programmable using the front buttons or the PC via infrared interface
• Mounted using M5 screws or mounting brackets
• 60-segment bargraph
• Displayed measurands are freely selectable
• Open collector output for alarm or energy count
• Loop test output
Typical Applications
