AC VOLTAGE CURRENT STANDARD

상품 상세설명

구입 및 기술문의 : 010-4221-0660

The 2558A is a cost-effective, high-precision instrument capable of outputting a wide range of AC voltages and currents for the calibration of AC measurement devices such as analog wattmeters, power meters, clamp-on testers, and current transformers. Intuitive front panel controls and various computer interfaces enable the 2558A to be operated manually or become integrated into an larger system.

The 2558A AC Voltage Current Standard offers users the best-in-class functionality and reliability customers have come to trust from Yokogawa.

A suite of features for verification and testing of AC measuring devices

Voltage, Current, and Frequency sweeping
Output Divider
Direct Readout of the Deviation
Digital Display of Output
Common Current Output Terminals

Go beyond conventional accuracy and output standards

The wide output ranges of 1.00 mV to 1200.0 V AC and 1.00 mA to 60.00 A AC mean that the 2558A is the instrument of choice for the cost effective calibration of AC analog meters. Rotary controls and a range of computer interfaces enable the 2558A to be intuitively operated through the frontpanel or controlled by an ATE system.

High Accuracy

AC Voltage: +/- 0.04 %
AC Current: +/- 0.05 %

The 2558A AC Voltage Current Standard is more than sufficient to calibrate meters with a class 0.1 % accuracy.

High Stability

AC Voltage/Current: +/- 50 ppm/h

+/- (20 ppm of range + 30 ppm of range)/h

Perform measurements with high repeatability over time

Wide Output Range

AC Voltage: 1.00 mV to 1200.0 V
AC Current: 1.00 mA to 60.00 A

6 voltage ranges (100 m/1/10/100/300/1000 ([V]))
4 current ranges (100 m/1/10/50 ([A]))

The generation range is 0 to 144 % of range

Wide Frequency Range

40 to 1000 Hz (Frequency accuracy: +/- 50 ppm)

The 2558A provides fixed frequencies of 50/60 Hz (commercial) and 400 Hz (marine and aviation), as well as variable frequencies from 40 to 1000 Hz.

The high frequency accuracy of the 2558A (50 ppm) also enables it to be used to calibrate frequency meters.

Multiple 2558A units can be synchronized using the internal phase shifter. This means that two 2558As can be used as accurate sources of voltage and current for calibrating power meters.
