Multifunctional Panel Meter PM 835

l         High Sample Rate: the synchronous sampling rate reach as high as about 6kHz.

l         Real-time  Operation: within 2mS after very cycle, the meter can liquidate all the  RMS value, power and other parameters to meet the requirement of  protected-level operation.

l         High Communication Rate:RS485 :1200 bps-115.2kbps.

l         Flexible communication protocol: each meter supports several usual protocol addresses or specially designed protocol addresses .

l         Analysis of Higher Harmonic : harmonic measurement:2^nd-60^th, the harmonic algorithm accuracy: 0.2%；the accuracy of the whole meter :0.5%

l         Abundant  Statistical Data: the meter can calculate the demand and the maximum or  minimum of the voltage ,current and power with the RTC time label to  choose.

l         High  Reliability: the meter has passed 4 level EMC test and can operate with  full voltage under the perceptual power-fail intelligent storage  system.
