NAGKT-III Three-Phase AC and DC calibration meter (three-phase power supply)
Also called name
Three-phase AC and DC meter, three-phase power supply, portable meter, integrated meter calibrator, three-phase active and reactive power meter, three-phase phase meter, three-phase meter calibration table calibrator
Overview
NAGKT-III-type three-phase AC and DC calibration table (three-phase four-wire system) is a new generation of portable table meter integrated meter calibrator. The product has the appearance of the United States, full-featured, excellent indicators, high reliability, simple operation and so on. Phase table, power factor meter, frequency table, synchronization table, single-phase power meter, three-phase active and reactive power meter, phase table, power factor meter, frequency meter, All kinds of energy meter.
Main function and characteristic
1, DSP-based digital signal synthesis and data acquisition and processing technology, making the device output stable and reliable, high precision, excellent indicators. Device class 0.1.
2, the output AC (three-phase) voltage, current, DC voltage, current
3, voltage, current range can be set according to the table under test, automatic shift.
4, the table source of one, with power, frequency, phase, power factor and AC and DC voltage and current standards, without the need to reprovision the standard table manually or automatically check a variety of instructions Meter, error. During calibration, both primary and secondary values can be displayed at the same time.
5, the calibration results can be stored, preview.
6, the configuration of a powerful computer management platform, through computer verification, transmission, printing and data management.
7, large-screen LCD display, pop-up menu in English and Chinese, the cursor any move to provide online help prompts, the operation is very simple, display rich content.
8, the device has an external software calibration.
9, load capacity, can be directly with 1uF capacitor (100V file)
10, multiple protection: power linkage protection, current limit protection, automatic power amplifier output off.
11, strict overload test, the shock test, misuse test, high-temperature aging test, the reliability of abnormal good.
12, use German standard chassis, small size, light weight, easy to carry.
