J7-20A Panel Energy Meter, AC 80–300 V, Up to 20 A
Read electrical values at the front of a suitable equipment panel. The J7-20A AC meter combines voltage, current and selectable power-related readings in one display. It is for qualified installers who can provide a correctly rated enclosure, wiring and circuit protection.
- ✅ Review a connected load at the panel — Voltage and current readings share the front display.
- ✅ Compare usage between checks — The energy counter records consumption for the connected load.
- ✅ Check more than instantaneous power — Selectable views include frequency, power factor and loaded operating time.
- ✅ Read in a dim cabinet — The backlight can be switched at the meter.
- ✅ Notice a threshold on the display — Adjustable voltage and power prompts use flashing indications.
Electrical readings within a compact panel opening
The meter fits a stated 63 × 63 mm opening, with a 68 × 68 mm front and approximately 22 mm depth. Rear screw terminals provide the direct connection arrangement. It is a component for an enclosed electrical installation, not a plug-in socket meter.
The stated voltage range is AC 80–300 V, current up to 20 A and power up to 4.4 kW. All limits apply together, with wiring and protection selected for the actual circuit. Flashing threshold prompts are visual indications, not a circuit breaker or automatic overload disconnection.
The energy and time counters can be reset, and retained data after power loss is stated. Loaded operating time does not count an unloaded circuit. One meter is supplied; enclosure, wiring and protective devices are not confirmed included. Installation must be completed with the supply isolated by a suitably qualified person.
Follow the supplied terminal and settings instructions.
Display window dimensions are stated as 41 × 48 mm.
Rear terminals require an enclosed, correctly protected installation.
Check the panel opening and front dimensions before fitting.
Voltage, current and the selected additional value share the display.
Threshold settings produce visual prompts, not circuit isolation.
The selectable view includes instantaneous power.
The energy counter records the connected load's use.
Power factor is one of the selectable values.
Loaded operating time can be displayed.
