YD2050 Intelligent Power Monitoring Instrument
YD2050 Intelligent Power Monitoring Instrument I. Product Functions and Features The YD2050 acquisition system consists of a host (YD2050), 40 switch
Product details
1、 Product functions and features- YThe D2050 acquisition system is composed of a host computer（YD2050）、 40 way switch quantity（YD2050-40K) and 40 current channels（YD2050-40I) Measurement module and external sensor（YComposed of D2050-50/10 or KD2050-500/10, it can simultaneously measure over 100 states and electrical parameters
- Host（YD2050) is used to measure 34 parameters of a main circuit, including 3I, 3V, 3U, 3P, ∑ P, 3Q, ∑ Q, 3S, ∑ S, F, PF, ± ∑ Wh, ± ∑ Qh, and zero line current; 40 channel switch module（YD2050-40K) can be connected to 40 switch signals and 40 current modules（YD2050-40I) can measure 40 current channels; External current sensor andYD2050-40I is compatible for use, with a maximum input current of 63A and 630A (to be ordered by the user according to actual needs)
- Adopting a dot matrix LCD display, the Chinese English interface can be switched, and all statuses and data can be output through the RS485 serial port,
