Description
D85-2042A digital AC voltage and ammeter display the measured AC voltage and AC current simultaneously on the same instrument. The meter does not need to increase the working power supply and AC transformer (the meter is equipped with a precision small transformer), and the measurement is very convenient and accurate. Widely used in substation automation, power filters, timing devices, audio power amplifiers, distribution boxes, power distribution cabinets, voltage stabilizers, teaching appliances, small household distribution boxes, etc.
Specification
1. Measurement accuracy: 1%±2 words
2. Measuring range: AC voltage: AC80-300V 200-450V, AC current: AC0.1-100A 1.0-199.9A [Note: The meter comes with a miniature precision transformer, select 100A to measure the current between 0.1-100A, and measure The accuracy remains the same. If you select 200A for current measurement above 100A, the measurement accuracy remains unchanged. 】
3. Power consumption: 0.2VA
4. Measuring speed: about 2 times per second
5. Dimensions: 70*40*39mm, visible screen size: 48×24.5mm
6. Installation size: 68*38mm (embedded installation)
7. (100A transformer hole diameter 15.5mm) can meet the national standard 21-25 square (mm) standard copper wire passing through
8. (200A transformer hole diameter 24mm) can meet the national standard 30-45 square (mm) standard copper wire through
9. The lead of the split type transformer can be extended by about 0.5-3 meters by itself (using 0.3 square wire or ordinary bulb wire, it does not affect the measurement accuracy) and then use a cable tie or wire binding to fix it at the ideal position of the device. .
Note: This instrument is only suitable for pure AC 50-65HZ mains power supply. It cannot be used for thyristor, square wave inverter output and sine wave circuit measurement, otherwise the instrument will be permanently damaged!
