3IN1 Din Rail LED Display Voltage Current Frequency Meter 80-300V 200-450V 0-100A Voltmeter Ammeter Three in one with Extra CT(250 to 450V)

Voltage Testers Din-rail AC Digital-display meter can measure and display the AC voltage and current, voltage frequency at the same time. Technical Indicators 1. Accuracy: 1%±2 words 2. Displayer:AC voltage and voltage frequency show with four yellow LED of 0.32 inch, AC current show with four green of LED of 0.32 inch 3. Measure Range: AC voltage: AC 80.0 - 300.0V or AC 250 - 450V ( PLEASE CHOOSE THE TYPE YOU NEED) AC current: AC 0.00-100.0A Frequency: 45.00 - 65.00Hz 4. Speed: 2 times per second 5. size: 54*80*64 6. Installation: Din, you can install the meter with the air-switch (like c45) on the same din rail. 7. Only for extra CT, There are no CT inside the meter. Application Method 1. Connect the measuring voltage to the 1 and 2 terminal. 2.Connections of meter with internal current transformer as graph 1. Make the wire through the hole in the meter and the direction chose arbitrarily. 3.Connections of meter with external current transformer as graph 2. Make the wire through the hole in the meter, and connect the two wires of the secondary transformer to the 3 and 4 terminal. The meter can only use to measure 45-60Hz AC city electricity, it will be destroyed when use to measure square wave, output of inverter and correction sine wave. ========== Battery Included : No High-concerned chemical : None Voltage range : Other Certification : CE Origin : Mainland China Model Number : D52 DIY Supplies : Electrical Dimensions : 54*80*64 Operating Temperature : Normal Accuracy Class : 1%+- words Power Supply : AC Display Type : Digital Only Measuring Range : 80-300V, 0-100.0A
