Model# 2493

Triple Function Digital Switchboard Meter

The Model 2493 (Triplefunction) Digital Switchboard Meter was developed to provide customers with a versatile AC digital power meter.

  • End user programmable for CT ratios and PT ratios
  • End user selectable legends Watts, kWatts and mWatts, etc.
  • Non-volatile memory. If loss of power occurs, all settings will remain the same.
  • Accuracy of + 0.2% of reading, + 0.1% Full Scale.
  • True RMS current and voltage measuring. Most desirable if distorted sine wave is present.
  • Security of settings………. Complete removal of cover is required to access selectable or programmable
    variables. Four push buttons are used for quick setup, except 2493 with front panel configuration.
  • Display averaging………… Programmable from 1 to 25 samples to eliminate annoying digit bounce.
  • RS485 communication option allows up to 32 units to be networked together for remote reading.
  • Analog output option allows ability to connect to data acquisition systems.
  • Complete operating instruction manual included with each meter.
  • NIST Calibrated Certificate/Test data available as an option.
  • Modbus communication option allows connection to existing control systems.
