BOQNZN50A AC Power Meter, 240V NEMA 14-50P to NEMA 14-50R LCD Display Digital Multimeter Tester with 1.3FT 10AWG Cable, Multifunction Energy Monitor Voltage Current Frequency Power Factor Outlet Monitor
Main highlights- Wide Application: Support various electrical appliances within 300V. The 14-50R socket is mainly used in power supplies such as washing machines and dryers, widely used in home appliance work and EV charging. As for AC power meters, it is widely used in industrial, power distribution systems, renewable energy installations, laboratories, and research facilities. Provides critical data and analysis for energy management, load balancing, and troubleshooting electrical issues related to power consu
- High-Precision Monitoring: With its sensitive electromagnetic coil, watt meter panel can accurately monitor various data such as voltage, current, power, frequency, and power factor in real time. Product parameters: Voltage: 40-300VAC, Current: 0-50A AC, Power Draw: 0-9000W, Frequency: 45-65HZ, Power factor: 0.00-1.00PF, Power Usage: 0-99999kwh
- Flame Retardant Material: The whole body of the monitor is made of PC flame retardant shell, which has excellent high temperature resistance, and will not produce dripping and burning at high temperature, which reduces the risk of fire spreading and provides additional security. It has good wear resistance and impact resistance, can withstand a certain degree of impact and pressure, and improves its service life
- Electricity Safety: Aging electrical equipment may have various problems, such as over-power, over-rated current, overload, etc., which may lead to equipment failure. Use BOQNZN LCD display digital multimeter, the power consumption status of these devices can be monitored in real time, abnormal data can be found and eliminated in time, and old devices can be replaced or upgraded, reducing potential safety hazards and ensuring the normal operation of the devices
- Data Recording and Recovery: Even in the event of a power outage, historical power consumption data can still be retained, which is useful for tracking equipment power consumption and analyzing power consumption trends. Long press the button on the right side of the electrical usage monitor to reset the recorded data, which can be used to monitor another electrical appliance
- Cost Control and Energy Saving: 50A AC power meter through real-time monitoring of power consumption, energy waste or inefficient equipment can be identified. Voltage fluctuations, voltage sags, swells, transients, and other disturbances that may affect the performance of electrical equipment can be monitored, so that corresponding measures can be taken to optimize energy utilization and avoid unnecessary waste to obtain a more cost-effective way of using electricity
