YDD series power transmitterDetailed product description：

YDD series transmitter
SENECA Transducers
characteristic
Purpose: It is a type of input component for analog signal acquisition in remote control devices, computer inspections, and automation control systems. It is used to isolate and transmit electrical parameters such as current, voltage, frequency, power, power factor, and electrical energy in the power grid into linear DC analog signals. It can be widely used in power systems, industrial systems, building systems, and other industrial and coal mining enterprises.
Measurement: single-phase AC, three-phase three wire, three-phase four wire
Voltage transmitter, current transmitter, power transmitter, power factor transmitter, frequency transmitter, electrical energy transmitter, etc
Accuracy: ± 0.2% RO
