Single-phase energy metering with an LCD, 4G connectivity and remote relay switching. Supports 32 weekly schedules, voltage/current alarms, configurable automatic disconnection and 35 mm DIN rail mounting.
Monitor and switch supply circuits in shops, rental properties, charging installations and equipment sites. Local controls and the remote platform provide access to electrical data and switching operations.
View voltage, current, active power, cumulative and daily energy, power factor, frequency and temperature.
Control the internal relay from a phone or computer, with local ON/OFF buttons and pulse operation. An external SMA antenna provides 4G connectivity.
Store up to 32 tasks with weekday, time and switching actions for recurring operating hours.
Configure overvoltage, undervoltage and overcurrent alarm thresholds and optional automatic relay disconnection.
The LCD provides live measurements, power data, a current curve and switching events. Three buttons operate ON, OFF and page selection.
35 mm DIN rail mounting for distribution panels. Contact Zhenming Electronics for circuit selection, platform access and project integration.
Review branch consumption and arrange switching around operating hours.
Monitor current, power and energy, with remote switching and threshold alarms.
Use the LCD for local inspection and the platform for online status, measurements and operating records.

Review voltage, current, active power, accumulated and daily energy in one circuit view, with power factor, frequency and temperature adding context. Name store, rental-property or auxiliary-equipment circuits by purpose, then use live data for present demand and energy totals for operating-period review. Remote access complements the local LCD for duty and inspection teams.
The 35mm DIN rail enclosure fits a single-phase panel arrangement. ON, OFF and page buttons support local work, while 4G and the external antenna connect the remote platform. The LCD shows live readings, power, a current curve and switching events. Use consistent circuit names for handover and allow panel space for the antenna, terminals and maintenance access.
Up to 32 weekly tasks align with opening, lighting or equipment periods, and pulse operation covers short triggers. Overvoltage, undervoltage and overcurrent use separate alarm and disconnection thresholds, with the configured response selected for the circuit. Recording schedules and thresholds with the circuit purpose helps operators relate actions, events and energy changes.
Alarm thresholds identify out-of-limit conditions. Disconnection thresholds govern the configured automatic opening action. Set them according to the circuit so notification and switching have clear roles.
Use store, panel and circuit-purpose names and groups. Align field labels, platform devices and operating records so different staff can identify the correct single-phase circuit.
No. The meter connects over 4G cellular service and requires adequate network coverage.
Local buttons operate the relay and display pages. Remote functions require an active connection.
0–40 A is the stated current measurement range. Relay capacity and load compatibility follow the device nameplate and selected configuration.
Overvoltage, undervoltage and overcurrent thresholds support configurable automatic relay disconnection.
The Chinese manual covers appearance, display pages, wiring, platform operation, alarms and troubleshooting.
