Yg889E-9Sy Power Meter Digital Multifungsi Dengan Layar Lcd Rs-485

Multi-function power meter has measurement, display, digital communication and electrical pulse output functions. It is able to accomplish power measurement, energy metering, data display, collection and transmission, and can be widely used for transformer substation, power distribution, intelligent building, company. It can measure current, voltage, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy, inductive capacitive energy, positive and negative reactive power. The power meter is easy to operate, safe, accurate, durable, intelligent, and energy saving. Housing is made of flame retardant ABS material, the structure is more secure. Plug type connectors are more convenient to wire. Designed with many heat dissipation holes on the back for more safe use. High quality blue backlight LCD screen offers a high-definition display on day or night. Support RS485 communication. Display: 4-digit Insulation Resistance: greater than equal 100MΩ Working Environment: Temperature: -1055°C; Relative Humidity: less than equal 93%; No corrosive gas; Altitude: less than equal 2500m Note: 1, The meter should be connected to power for 15 minutes before use. 2, Protect it against vibration or impact and do not use it in environment of mu dust or noxious gas. 3, Input wire should not be too long. If measured signal input terminal is too long, please try using twisted-pair shielded wire. 4, If signal has high frequency interference, low frequency filter should be tried using in wire. 5, During long-term storage, please connect it to power for at least 4 hours once every three months. 6, For long-term storage, it should be kept in temperature - 25℃ 55℃ and away from direct light. 7, If meter does not display, please first eck if the voltage of auxiliary power supply is in the normal range. 8, Terminals of CTcircuits must be connected tightly, ensuring reliable input/output contact. 9, Do not use PT signals as auxiliary power, in
