Description

Used product. The LIFASA PECA 20700300A set consists of 3 power electronics capacitors, each with a nominal capacitance of 30 µF ±10%, a rated voltage of 700 V DC, and a rated AC voltage of 400 V AC.

The components are designed for use in power circuits, conversion systems, and electrical filtering applications, where stable capacitance is required in the presence of high voltages.

The set includes the three capacitors in an assembled configuration, with a metal structure and connections using threaded terminals. Normal signs of previous use are present, particularly on the hardware and metal connection components. Electrical functionality cannot be determined by visual inspection alone.

⚙️ Technical Specifications

• Brand: LIFASA
• Series/Model: PECA 20700300A
• Quantity: 3 capacitors
• Rated Capacitance: 30 µF per capacitor
• Tolerance: ±10%
• Rated Voltage: 700 V
• Rated AC Voltage: 400 V AC RMS
• Class/Series: HSF 25/070/56
• Marking: 560-12

The set therefore has a nominal total capacitance of 90 µF if the three capacitors are considered individually in the same electrical configuration. The actual equivalent capacitance depends on the type of electrical connection used in the equipment.

⚡ Function in the Electrical System

The LIFASA PECA capacitors are intended for power electronics applications, where they may perform functions such as:

• Voltage filtering
• Electrical circuit stabilization
• Reduction of oscillations and unwanted components
• Temporary energy storage
• Support in AC/DC and DC/AC conversion systems
• Industrial applications involving high operating voltages

The configuration with 3 identical capacitors is particularly suitable for systems requiring a multiple capacitor bank with uniform electrical characteristics.

🏭 Construction & Installation

The three capacitors feature a cylindrical metal construction with connections made through threaded terminals.

The group is held together by an assembled metal connection structure. This configuration may facilitate replacement of an original capacitor group, provided that the electrical schematic, terminal arrangement, and mounting system are verified beforehand.

During installation, proper tightening of the terminals and connections must be ensured to prevent loosening, overheating, and loss of electrical contact.

🌐 Applications

The set may be used as a replacement in various industrial and power electronics equipment, including:

• Industrial inverters
• Static converters
• AC/DC and DC/AC systems
• Electrical drives
• Filtering equipment
• Industrial power supplies
• Energy conversion and management systems
• Electrical power cabinets and equipment

For replacement purposes, compatibility must be carefully verified against the original component, considering capacitance, voltage, current, frequency, dimensions, and connection configuration.

🛡️ Safety & Product Condition

⚠️ WARNING: HIGH-VOLTAGE APPLICATION CAPACITORS.

The capacitors may retain a dangerous electrical charge even after the equipment has been disconnected from the power supply. Before any handling or intervention, they must be properly discharged and the absence of residual voltage verified using suitable test equipment.

The set is used and shows signs of previous installation, including surface oxidation on the hardware and metal connection components.

Electrical functionality is not guaranteed based on visual inspection alone. Before use, it is recommended to test each of the three capacitors individually by measuring capacitance and checking insulation.
