Pepperl Fuchs KFD2-STC4-EXI Transmitter Power Supply
Pepperl Fuchs KFD2-STC4-EXI Transmitter Power Supply
Product Description :
- It is a specialized power supply designed to provide stable and reliable electrical power to the transmitter in communication systems, such as radio, television, wireless communication, or remote sensing equipment.
- The power supply is crucial because transmitters require high and consistent power levels to function effectively and maintain signal integrity. Whether for analog or digital transmission, the power supply needs to meet the transmitter’s voltage, current, and power demands while maintaining safety, efficiency, and low noise.
- Ensures that the transmitter receives a consistent and stable voltage, regardless of fluctuations in input voltage. This is particularly critical in communication systems where signal integrity and performance can be degraded by even slight voltage variations.
-
A Transmitter Power Supply provides isolated and regulated DC power to 2-wire and 3-wire transmitters used in industrial process control systems. It ensures consistent, interference-free power to devices like pressure, temperature, level, and flow transmitters, while also allowing accurate signal transmission back to the control system (PLC, DCS, or SCADA).
-
These units are designed with high noise immunity, galvanic isolation, and built-in protection, making them ideal for harsh industrial environments.
