Active filter how to sure product selection?

active filter how to affirm the product selection?

① understand the installation capacity

active filter installation capacity is by the management of harmonic current output can be expressed, the unit is ampere (a). The larger the installed capacity of active filter, the higher the total price. For example, a 300A active filter of the same brand is more expensive than a 100A active filter.

1. The load characteristics of each user are different, so the harmonic spectrum distribution is different. For example: some loads are mainly based on 3,5,7 harmonics; some load harmonics are very rich, with 2 to 25 harmonics, or above harmonics. 2. Each brand of different series of active filters can filter out the number of harmonics is not the same. Some active filters can only filter 25 times and the following harmonics, some active filters can filter 50 times the following harmonics, these indicators on the manufacturers are not the same.

If the number of harmonics that the active filter you choose can handle cannot cover the user's main harmonics, the final result is that the harmonic filtering effect is not good enough to handle the user's request for harmonic filtering. LBAPF-TY series of general-purpose active filter installation mainly to 3, 5, 7 filter-based.

source filter has three types: modular, wall-mounted and whole cabinet structure, they are all composed of APF power unit, the only difference is the shape structure, size is different. 1. The whole cabinet type active filter installation is composed of one or several APF power units, which can be directly installed on the project site to prevent the problem of users from setting themselves, and is simple and convenient. The maximum capacity of a single whole cabinet can be 500A.

2. Wall-mounted

The installation of wall-mounted active filter is to meet the needs of customers with small capacity requirements and limited requirements for device space, which can save space. There is 50a. 75A and 100A and other specifications to choose from.

3. Modular Collar

This kind of products can meet the needs of users who have complete sets of talents and need to save money. We can provide you with APF modules. You can assemble them into the cabinet by yourself. The module specifications are 50A, 75A and 100A, and the combination can be matched arbitrarily.
