FP3LDLD02M7 is a flat 3-phase power factor controller. This product has been designed for optimizing power factor up to 0.96 and THDc (Total Harmonic Distortion current) unbalance lower than 5%. This power factor controller is suitable for three-phase loads that are connected to the AC power network. It is also applicable for all kinds of motors and other inductive loads where the need for power factor correction is necessary.

The application field of FP3LDLD02M7 is in low voltage systems up to 500V (440Vrms). It can be used mainly in commercial setups to monitor the current taken from the AC power network. In some cases, such as in data centers, the power factor controller is also used for active load balancing so that the harmonic distortions do not exceed a certain limit. Furthermore, the power factor controller can also be used in residential buildings where they are integrated to the residence AC circuit in order to reduce power wastage.

The working principle of FP3LDLD02M7 consists of two parts: phase shift and true power factor adjustment.

In the phase shift process, a control signal is sent between the inductive load and the AC power network, so as to regulate the load current in accordance with the value of the voltage of the AC power network. This process eliminates the in-phase harmonics (above the fifth harmonic) and reduces the distortion of the overall load current.

On the other hand, the true power factor adjustment process begins after the current and voltage adjustments are completed. The overall power factor is dynamically regulated through the adjustment of the power factor control ranges to their lowest point.

Additionally, FP3LDLD02M7 has a built-in over-voltage protection which limits the voltage increase in case of fault or short circuit conditions. This ensures the safety of the system. The device is also waterproof, dustproof, and anti-corrosive, which makes it ideal for use in harsh environments.

In summary, FP3LDLD02M7 is a flat 3-phase power factor controller which has a wide range of applications. It can be used for optimizing power factor up to 0.96 and THDc (Total Harmonic Distortion current) unbalance lower than 5%, and is suitable for use in commercial, residential, and industrial environments. It also provides over-voltage protection, which ensures the safety of the system.
