DYT 480B ເຄື່ອງວັດແທກພະລັງງານຄວາມແມ່ນຍໍາສູງ (DC: 0.5 ~ 1 KHz)
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)
