480B High-precision Power Meter
♦ Overview
If connected with the integrated thermal analyzer, the load power meter can provide multi-dimensional data of voltage, current, power and temperature at the same time for comprehensive analysis, such as the relationship between temperature and power of components, heating conditions under different voltages during heating material analysis, etc.
Dianyang Technology has completed the alignment work, and is able to provide 480B High-precision Power Meter and Dingyang DC Load Analyzer.
The design of 480B adopts an advanced 32-bit high-speed processor and a dual-loop 24 bit AD converter, with characteristics of high precision, wide dynamic range, as well as compact and dexterous structure. It is a new-generation touch screen digital power analyzer. Its RS232/485, USB, Ethernet and other interfaces can satisfy the different demands of users for communication testing.
♦ Basic technical indicators:
| Technical indicators | Technical parameters |
| Bandwidth | DC: (0.5 - 1) KHz |
| Input mode | Floating input is adopted for both voltage and current |
| Display update | The update cycle can be set between 0.1 and 5 seconds |
| Line filtering | Cut-off frequency of 500Hz |
| A/D conversion | The sampling period is about 70μS, 24 bit; simultaneous sampling of voltage and current is supported |
| Input impedance | The voltage input impedance is about 2MΩ, the current input impedance is about 0.5Ω at low level and about 4MΩ at high level. The input impedance of the signal input terminal of the external sensor changes with the input voltage. For example, when the input voltage is 10V, the input impedance is about 100kΩ; and when the input voltage is 2V, the input impedance is about 20kΩ. |
| Zero calibration method | It will calibrate to zero whenever the measuring range is changed or the measuring mode is changed. |
| Measuring mode | True RMS, voltage mean, AC, DC |
| Overall power consumption | < 10VA |
| Working power supply | AC: 100V - 240V 45-440Hz; DC: 100V - 300V |
| Communication interface | USB (standard), RS-232/485 (standard), Ethernet (optional) |
