Product Description

DZ****3B Portable Three Phases Energy Meter Testing Equipment Main Performance: The operation can be controlled via computer software or special keyboard. Program controlled power source, high precision reference standard meter. Output voltage and current adopts soft-stop and start, alarm protection when voltage short circuit and current open circuit, Voltage, current, frequency and phase shall be set freely under manual calibration. Output voltage and current signal can be set according to the city power. Small size, high stability and portable. Index: Accuracy class: 0.*5, 0.1. Output voltage: *0, **0, **0, **0, 0－**0% of each range can be continually adjusted. Output current: 0.1A, 0.5A, 1A, 2.5A, 5A, *0A, *0A, *0A, 0－**0% of each range can be continually adjusted. Phase scope: 0～**9.9°, adjusted resolution is 0.1°. Three phase un-symmetry: <0.5°. Output power stability: <0.*5%. Output voltage and current distortion: <1.0%. Range of frequency is from *5.*0 to *5.*0Hz, adjusted resolution is 0.1Hz. Power supply: AC **0±*0%.
