H-127 Potentiometers, Variable Resistors

H-127 is a current-to-frequency converter designed for industrial applications. It\'s mainly used to measure the resistive current by converting it to a frequency signal. It is an essential device for many applications, such as power engineering, energy measurement, monitoring and control, power quality, communication systems and so on.

Principle of Operation

H-127 converts the current signal that passes the device to a frequency signal proportional to the current, while maintaining its linearity. It features a wide current range, and its frequency output changes linearly and continuously with the size of the current passing through it.The current-to-frequency conversion principle of the H-127 is based on an electrical circuit similar to a Wheatstone bridge. The current to be measured passes through the resistor arm of the bridge. The fixed and variable arm of the bridge consist of a variable resistance that receives a fixed voltage at its terminals. As the current passing through the resistor arm increases, the voltage at the variable resistor terminals will decrease. This voltage changes will then be picked up by an operational amplifier and the output frequency of the circuit will be adjusted accordingly.

Application Fields

H-127 devices are most widely used in measuring electrical parameters such as voltage, current, power and energy. It can also help to measure the frequency, frequency response, angle and phase of a signal.H-127 is also suitable for use in various applications, including motor control and protection, generator protection, battery systems, automotive, home appliances, power supplies, UPS systems, etc. It can also be used to monitor and control the quality of power grids.
