ZX3030A AC Program Controlled Three Phase Standard Power Source Long Life

Introduction

ZX3030A three-phase program-controlled standard power source adopts with the integrated structure of meter and source, full digital closed-loop standard source technology, and uses a series of advanced devices such as embedded system, large TFT screen, CPLD chip and high precision A/D, D/A. It can be widely used in electric energy metering industry, electrical laboratory and other related departments, and is easy to carry to the field.

Features

1. Using touchable screen and film button.

2. Embedded high-level standard power watt-hour meter and digital closed-loop feedback based on it. Other parameters such as voltage, current, frequency can also be used as standard.

3. current limit protection, voltage short circuit protection, current open circuit protection and other functions.

4. Within the allowable output range of the instrument, users can arbitrarily set the rated voltage and current gears of three-phase voltage and current.

5. There are abundant current and power factor test points, which make it easy to configure various calibration schemes.

6. It can check all kinds of single-phase, three-phase and active and reactive watt-hour meters.

7. The large amount of data storage makes it easy to query the validation data.

8. With RS232 serial port, it is convenient for computer control and upgrading software.
