Power Line and Environmental Monitor OM-PQR1010

Feature

Electronic equipment is damaged more often by power disturbances than by fire, theft and vandalism combined. Intermittent power problems are the most expensive hidden expense to users of microprocessor-based equipment.

 

The OM-PQR1010 power quality recorder is a state-of-the-art, fully integrated instrument that measures, records and reports power disturbances, aiding in the analysis of power quality in medical, commercial and industrial applications.

 

The OM-PQR1010 monitor unit will detect a wide range of power disturbances including spikes, sags, surges, common mode noise, dropouts and high frequency noise on two phases of ac voltage and one dc voltage channel; it will also test the temperature, humidity and ac current. For ac current measurement, the OM-PQR1010 is equipped with a pair of banana jacks designed to accept a 10 mV/output current transducer (CT). Disturbances detected on multiple channels are recorded by their time, date, magnitude and duration in a non-volatile RAM memory. Stored data can then downloaded and analyzed by connecting the OM-PQR1010 to your PC’s serial port and running the included Windows data analysis software. Input connections to the OM-PQR1010 are made between the safety connectors on the back of the unit and the circuit panel to be tested. The OM-PQR1010 operates on standard 110 Vac/220 Vac power. Once plugged in, the OM-PQR1010 immediately begins testing the signals on the input connectors.
