Description
AC Voltmeter and Ammeter 50–500V 10A
This AC voltmeter and ammeter measures voltage (50–500 V AC) and current (0–10 A) simultaneously on the same AC circuit. It is powered directly by the measured line, so no separate power supply is required. The compact panel meter has a stated class 0.1 accuracy and displays voltage and current in real time.
🔧 Technical specifications
- AC voltage range: 50–500 V

- Accuracy: class 0.1 (±0.1%, ±1 digit)
- Display: backlit LCD, simultaneous V and A readings
- Power: supplied from the measured AC phase and neutral
- Certification: CE
- Panel dimensions: 48 × 29 × 22 mm; cut-out: 45 × 25 mm
💡 Typical applications
- Monitoring voltage and current in domestic or industrial installations
- Checking the consumption of machines, motors, and pumps
- Installation in electrical panels and control desks
- AC circuit troubleshooting and testing
- DIY energy-monitoring projects
🛠️ Pinout and wiring
| Terminal | Function | Typical connection |
|---|---|---|
| L+ | Phase (measured voltage and meter supply) | 50–500 V AC phase line |
| N− | Neutral (voltage reference and supply) | AC neutral line |
| I+ | Current input + (internal shunt) | Load phase wire, series input |
| I− | Current input − (internal shunt) | Load phase wire, series output |
Connect L+ / N− to the line being measured to power the meter. Then route the load’s phase wire through I+ → I− to measure current. AC mains voltage can cause serious injury; disconnect power before wiring and use appropriately qualified personnel.
