ASMJ Ac Filter Power Condenser
Jinneng electric has developed the ASMJ Ac Filter Power Condenser,which is a self-healing AC filter capacitors. These products are designed for systems with high harmonic content and are used in conjunction with filter reactors. They provide a low-impedance path for one or multiple harmonic currents in 50Hz or 60Hz AC power systems, effectively absorbing high-order harmonics while also serving as reactive power compensation.
- Product Introduction
In recent years, with the rapid development of technology, power systems have increasingly use rectifiers, frequency converters, and large power electronic equipment. harmonic pollution in the power grid has become more seriously. Harmonics can damage capacitors, shortening their lifespan.
To deal with the increasingly challenging power grid environment, our company has developed the ASMJ Ac Filter Power Condenser. It is designed for systems with high harmonic content and are used in conjunction with filter reactors. They provide a low-impedance path for one or multiple harmonic currents in 50Hz or 60Hz AC power systems, effectively absorbing high-order harmonics while also serving as reactive power compensation.
Product features:

Installation and operation guidelines:
1. Rated Voltage Selection
Consideration for voltage rise caused by series EMF in the circuit when selecting capacitor rated voltage.
Technical Note: Ensure the selected voltage rating accommodates potential overvoltage conditions during operation.
2. Multi-Capacitor Installation
Spacing Requirement: Maintain >30mm gap between capacitors.
Ventilation: Install in well-ventilated areas to facilitate heat dissipation.
Purpose: Prevents localized overheating and extends service life.
3. Re-power on After Shutdown
Critical Interval: Wait ≥3 minutes before re-power on to avoid voltage superposition (residual charge buildup).
Safety Rationale: Allows internal discharge resistors to reduce residual voltage below hazardous levels.
4. Terminal Connection Method
Recommend: Use flexible cables for terminal connections.
Advantage: Reduces mechanical stress on terminals due to thermal expansion/vibration.
Quality control:
●Our company has gotten ISO9001 quality system certificate and implement this quality manage system.
