MULTI POWER MONITOR Model: 53U

MULTI POWER MONITOR

Model: 53U

MULTI POWER MONITOR

Model: 53U - 1102 - AD4

Functions & Features
• Measures simultaneously several variables of a heavycurrent
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
• Conversion factors, system configuration, interval times
are programmable using the front keys
• Open collector output for alarm or energy count
Typical Applications
• Multi-functional power monitor incorporated in an electric
device: saves space, wiring works, and cost
