Overview:
π The AC 50-300V LCD Digital Panel Wattmeter is a sophisticated measuring instrument designed for monitoring various electrical parameters, including voltage, current, power, and frequency. With its clear LCD display, this device provides real-time readings up to 450V, making it a versatile tool for electrical engineers, technicians, and hobbyists alike.
π§ Key Features:
- Voltage Measurement: Accurately measures AC voltage within two ranges: AC 80.0-300.0V for low to medium applications and AC 200.0-450.0V for higher voltage systems.
- Current Measurement: Capable of measuring AC currents up to 99.99A, with a resolution of 0.01A, perfect for monitoring electrical loads.
- Power Measurement: Displays active power up to 45,000W with exceptional accuracy; at lower power levels, the resolution reaches 0.1W for precise readings.
- Electric Energy Tracking: Monitors energy consumption from 0 to 999,999 kWh, providing detailed tracking with varied resolution based on the range.
- Frequency Indication: Measures and displays power frequency from 45.0Hz to 65.0Hz, aiding in the analysis of electrical system performance.
- Compact Design: Dimensions of 79mm x 43mm x 48mm with an installation size of 76mm x 39mm make it easy to integrate into existing panels.
- Auto-Save Functionality: Equipped with a memory feature that retains energy measurements even when powered off, ensuring continuity in data tracking.
πͺΆ Installation Guidelines:
π§° To set up the wattmeter:
- Follow the provided wiring diagram to connect the green wire of the secondary current transformer to the blue terminal of the meter.
- Ensure the measurement circuit wire passes through the hole of the current transformer.
- Power up the device to initiate measurements and view results on the LCD display.
- To reset the accumulated electric energy to zero, press and hold the reset button for five seconds.
π Important Considerations:
- Ensure the correct voltage range is selected before use to prevent inaccurate readings or damage to the device.
- The AC200-450V model is strictly for use with 50Hz AC city electricity; misuse with inverter outputs or non-sinusoidal waveforms may lead to device failure.
- For accurate readings in three-phase systems, the AC80-300V100A model must have a neutral line; otherwise, the AC200-450V100A can only measure a single phase.
π οΈ This energy power meter is an essential tool for anyone needing precise electrical monitoring, whether for residential, commercial, or industrial applications.
