The PLM9805 current and voltage monitor is a versatile and easy to use electronic instrument, designed to accurately measure and monitor electrical circuits. It is a fully programmable monitor, which provides several operating modes. It has two independent inputs for measuring current and voltage, which can be read in both AC and DC scale as required. It is also equipped with a relay output, which can be used to activate external devices.

In its basic form the PLM9805 can measure and record voltage, current, frequency, temperature and any parameter related to power systems. It has two built in adjustable relays, which can be used to open or close electrical circuits. It has a wide range of alarm settings, which allow it to report any losses or gains detected in the monitored electrical system, or report any unsafe operating conditions. The adjustable relays provide a convenient means of controlling external circuits.

The PLM9805 is a suitable device for monitoring a variety of industrial and commercial systems, such as air conditioning, electrical power supply, building automation, wind turbines and PV systems. It is capable of detecting over-current, under-voltage, over-voltage, short circuits and other electrical hazards. It is programmable to alert via LCD mode, audible alarm or relays at any predetermined settings.

The working principle of the PLM9805 is extremely simple. It measures and records current and voltage using two independent inputs, which are connected to the circuit under test. The device then performs various calculations and functions, such as filter, delay, alarm detection, relay output, recording and reporting. The device also has an adjustable output timer which can be used to activate external circuits.

The PLM9805 is an ideal device for monitoring and controlling current and voltage in different applications. Its adjustable thresholds, accurate readings and various alarm settings make it a reliable and robust monitoring and control solution. It is suitable for use in medium to large sized industrial and commercial applications. The device is robust, user-friendly and highly reliable.
