Thiết bị đo công suất, Model: L53U-1211-AD4/A

MULTI POWER TRANSDUCER

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, setting data are
stored in the non-volatile memory at the power off.
• Conversion factors, system configuration, interval times
are programmable.
• Open collector output for alarm or energy count.
