Single Phase Energy Meter Digital Electricity Meter AC 40-300V 100A 1 Phase Electric Meter Wattmeter DIN Rail Watt Meter KWh Meter Type CT

General Description The SJLERST single-phase energy meter is a digital device designed to measure electricity consumption accurately. It is capable of measuring AC voltages ranging from 40 to 300V and currents up to 100A. Thanks to its colorful LCD screen with a full 178° viewing angle, it simultaneously displays six parameters: AC voltage, AC current, active power, power factor, frequency and electrical energy. Compact and lightweight, it is ideal for use in various sectors such as the chemical industry, power plants and automation systems.Technical Specifications Item Type: Watt-hour meter Model: D52-2066 Material: ABS Measuring accuracy: 1% ± 2 words Measuring range: AC voltage: 40.0-300.0 V, AC current: 0-100.0 A Current display resolution: 0.01 A Power frequency: 45.0 Hz - 65.0 Hz Power factor: 0.00 - 1.00 PF Active power: 0-30000W (resolution: 0.1W up to 9999.9W, 1W beyond) Electricity: 0-9999kWh (resolution: 0.01kWh), 1000.0-9999.9kWh (0.1kWh), 10000-9999kWh (1kWh) Measuring speed: about 2 times per second Installation method: DIN rail type Installation Connect the measured voltage to terminals 1 and 2 at the bottom left of the meter. The built-in transformer must be wired according to the wiring diagram provided. The measuring loop wire can pass through the hole under the meter or through the circular hole at the top.Connect the external transformer according to the wiring diagram and connect the wires to terminals 3 and 4 on the top left of the meter. Usage After powering on, the device will display the measurement parameters. To reset the energy measurement, hold the RESET button for 5 seconds. The device automatically saves data when the power is turned off and continues to accumulate previously saved data when reconnected. Other information
