PL120HB is a multifunctional monitoring device mainly used for protection and control in motor, transformer, generator, power distribution equipment and other power systems. It has the characteristics of stable performance, high accuracy, multi-function and high reliability.

The working principle of PL120HB is based on the joint action of current collect and voltage collector. It is composed of a host computer and a current and voltage collector, which are connected by data interface. Its main function is to collect the DC voltage and AC current data of the monitored equipment, and output it to the host through data interface, alarm, display and save the protection type of events.

The application fields of PL120HB are mainly distributed in the transformer, electric motor, converter and other important power system equipment. For example, it can be used in motor-driven hoist, electric motor-driven refrigeration equipment, motor-driven industrial drawing machine, etc. Its application also includes power system control, industrial control, intellectualized mechanical automation control and other fields.

PL120HB can be used for power and protection of high and low voltage equipments in power system, such as motor, transformer, generator and switch cabinet. It can realize functions such as automatic fault protection, alarm setting, automatic running monitoring, overload protection, high and low pressure protection, reverse rotation protection and so on. Also, it has good application effect on the DC power system. PL120HB monitors the three-phase voltage, phase current, line current, frequency, rotation, load disruption and other parameters of the DC power system in real time.

In addition, PL120HB can provide highly reliable protection and control for automatic operation of electric equipment. Its protection and control functions are complete, comprehensive, practically strong, and realize procedures such as setting, writing and testing. It can prevent power system power equipment from tripping in response to transient changes, or when there are threats of overload, undervoltage, overvoltage and other functions of the device.

PL120HB has the advantages of high performance, high accuracy, complete functions, strong practicability and ability to protect power equipment from damage. It has been widely used in various power and protection systems and proved to be an effective tool in enhancing equipment automation and protection levels, and making power system more intelligent and reliable.
