Frequently Asked Questions
Q: What type of electrical system is this three-phase energy meter compatible with?
A: This LCD digital energy meter is designed for AC 400V, 50Hz, three-phase 4-wire power systems. It is ideal for industrial panels, commercial buildings, and heavy-duty equipment circuits requiring accurate kWh consumption tracking.
Q: How is this energy meter installed?
A: The meter supports standard 35mm DIN rail installation, making it straightforward to mount inside electrical distribution panels or control cabinets. It can also be wall-mounted. Installation should always be carried out by a licensed electrician following local electrical codes.
Q: What is the pulse output used for on this kWh meter?
A: The 400 imp/kWh pulse output, isolated via optical coupling, allows the meter to interface with external data loggers, building management systems (BMS), or automation controllers. This enables remote energy monitoring and data recording without direct electrical connection to the metering circuit.
Q: Does this energy meter require a battery?
A: No, this meter does not require a battery. It is powered directly through the monitored electrical circuit, eliminating the need for battery maintenance or replacement.
Q: Can this meter handle currents above 5A up to 100A?
A: Yes. While the rated current is 5A, the meter supports a maximum current of 100A, giving you flexibility across a wide range of three-phase load applications.
