The LIART220A is a compact and robust current/voltage monitor relay with both single-phase and three-phase versions. The LIART220A can be used for monitoring the range of currents or voltages from 0.1 mA to 5A or from 10V to 300V. It provides reliable overcurrent, overvoltage or undervoltage protection in a wide range of applications in industries, including electrical, automation, telecommunications, HVAC and more.

The LIART 220A is specifically designed to detect and control overvoltage or overcurrent problems in one or more circuits. It comes with relay outputs that can be programmed and can be used to activate override controls or alarm systems. The relay outputs can also be used as direct alarms to cut off the power or start the cooling system. The potentiometer on the front panel of the device is used to adjust the trip point and the delay timer. The trip point may be set for either over or undervoltage/current alerts, and the delay timer can be set to vary from 0 to 5 seconds.

The LIART 220A also provides a host of adjustable features that allow the user to customize the device to their specific needs. It features adjustable pre-trip time, adjustable over-voltage alarm range, adjustable filter delay time, adjustable trip time, adjustable hysterisis, and adjustable time lag setting. All these features provide the user with flexibility and control when it comes to setting up the device.

The LIART 220A has an impressive accuracy range of +/- 1%. This means that the device can detect currents or voltages within +/-0.1% of the programmed level. The device also has a wide operating temperature range of -25°C to 70°C. This ensures that the device can operate without a problem in most environments.

The LIART 220A is a versatile and reliable monitor and control device. It can be used in a wide range of applications including power monitoring, overvoltage and undervoltage protection in electrical, automation, telecommunications, HVAC, and other applications. The device also has adjustable features, allowing users to customize the device to their specific needs. The device has a wide operating temperature range, ensuring that it can operate properly in different environments.
