As an advanced intelligent front-end digital capture devices, Digital Power Meter The power meter is widely used in various control systems, SCADA systems and energy management systems. Instrument AC sampling technology to measure grid current, voltage frequency, active power, reactive power, active power, reactive power and other parameters can be set via the membrane switch panel magnification with RS485 communication, alarm output, digital input / output functions. This power meter is designed for power monitoring requirements and power systems, industrial and mining enterprises, public facilities, intelligent buildings, intelligent power monitoring l Operating temperature: LCD display: -10 ℃ ~ + 45 ℃; LED display: -10 ℃ ~ + 55 ℃ l Storage temperature: -20 ℃ ~ + 70 ℃ Relative humidity, etc. l: ≤93% RH, non-condensing, non-corrosive gas l Altitude: ≤2500l C - with RS485 communication interface, using MODBUS protocol, DC4- 20MA signal everywhere 4 optional features l K - with digital input / output l M - Analog Output l J - relay alarm output 1, before using the instrument required power for 15 minutes. 2. Attention to prevent vibration and shock, do not use in a place of excessive dust and excess of harmful gases. 3. Input wire should not be too long, such as the signal input is longer Try shielded twisted pair cable. 4. If the signal is accompanied by high frequency interference, try low-frequency filter online. 5. Long term storage when not in use, the power once every three months at least 4 hours. 6, long-term preservation should avoid direct sunlight, should be stored at ambient temperature -25 ° C ~ 55 ° C. 7, such as instrument no display, you should first check the auxiliary power supply voltage in the range. 8. The display is not normal, check the input signal and the signal terminals tightened. 9. Unless the PT have enough power, or can not use the PT signal at the same time as an auxiliary power to ensure that the instrument work. 10, CT circuit current terminals are tightened to ensure that the inlet / outlet access to reliable, in order to avoid failure. 11. To calibration instruments, calibration equipment should be better than 0.1 in order to ensure that the calibration accuracy. Jiangxi Huajian Power Industry Co., Ltd.
