Understand Power Supply Loop Stability and Loop Compensation—Part 1

An unstable or marginally stable power supply can oscillate and cause increased ripples, voltage, current, and thermal stresses, and possibly damage the supply and its critical load devices. To check power supply feedback loop bandwidth and stability, loop Bode plots are widely used to provide accurate and quantified values of loop performances.

4-20 mA Current Loop | Basic Fundamentals - INSTBLOG

To generate the output, there must be a power source. We need to remember that the power source must supply a DC current. Many common voltages are used with 4-20 mA current loop like 9, 12, 24 V, etc. depending on the setup. It is important that the power supply must be greater than 10% of the total voltage drop across the loop.

Back to Basics: The Fundamentals of 4-20 mA Current Loops

A current loop requires voltage to drive the current. This is provided by the power supply, with the voltage of the supply labeled as Vtot. Current then flows through the loop, passing through each load. The voltage drop at each load can be calculated from Ohm's Law. The voltage drop V1 across R1 is: Figure 2. Ohm's Law

Current Loop Products - 4-20mA Current Loop - Maxim Integrated

Unlike voltage, current does not vary due to line resistance or capacitance—both which change with cable length. Current loops provide a high level of noise immunity. As a result, they are widely used in electrically noisy environments. Maxim provides a wide range of products designed for implementing and protecting 4-20mA communication links.

Current Loop voltage drop calculator - DIVIZE

When the power supply voltage to the current loop is to low, the required maximum current of 20 mA can not flow.The calculation shows the current will stick at a certain level. The PLC, DCS system or other receiver will not detect the insufficient voltage supply, so the measured current will be used as a normal measured value.

What is a 4-20 mA current loop? - Fluke Corporation

In a current loop, the current signal is drawn from a dc power supply, flows through the transmitter, into the controller and then back to the power supply in a series circuit. The advantage is that the current value does not degrade over long distances, so the current signal remains constant through all components in the loop.
