BY81JF SERIES INTELLIGENT CAPACITORS
Product information
BY81
SERIES INTELLIGENT CAPACITORS

Product details
The BY81 series intelligent capacitors, with Δ-type (2 units) or Y-type (1 unit) low-voltage power capacitors as the core, integrate microelectronics, sensing, network and advanced manufacturing technologies to achieve intelligence, miniaturization and modularization, representing a major breakthrough in low-voltage reactive power compensation technology.
Featuring a simple structure, easy production and lower cost, they can improve performance and simplify maintenance. They can be flexibly adapted to various low-voltage reactive power compensation scenarios, completely innovating the traditional equipment mode.

Integrates measurement and control technology with synchronous switch, precisely controls switching, eliminates bouncing, extends service life to one million times, with advantages of high reliability, low failure rate and low power consumption.

No inrush current during closing, zero-crossing switching, avoiding overvoltage, breakdown, arcing and restrike.

Reasonable compensation method, full functions, excellent performance, including high-grade power analysis function, and can be equipped with various peripherals.

Complete measurement and protection, covering temperature, harmonics, phase loss, three-phase imbalance and other protections.

Multiple units can be combined in a modular way, automatically generating a host, automatically switching in case of failure, with high intelligence and intuitive working condition display.

ABOUT INSTALLATION
It is recommended to have a professional electrician perform the installation when there is a power outage, which can avoid electric shock caused by improper operation and product damage caused by improper wiring (product damage caused by incorrect wiring is not a quality issue and cannot be returned or compensated);
REGARDING ORDERING
1. Before placing an order, please consult whether the product is suitable to avoid unnecessary trouble
2. Some models are unconventional and cannot be stocked. Please contact customer service to confirm the delivery time before placing an order
ABOUT DIMENSIONS
The product dimensions are measured using a vernier caliper and tape measure. Due to differences in tool sand manual measurement methods, there may be normal range errors in the results, which is a nomal phe.nomenon and not a problem with workmanship or quality.
DELIVERY
The warehouse will arrange the shipping route based on the size, quantity, and weight of the products. By
default, the shipment will be sent to the destination city via logistics and self pickup is required. If you need
to specify the logistics, please contact customer service for a note.
