Shanghai,Ningbo,Qingdao,Guangzhou,Yiwu,etcIn Uninterruptible Power Supply (UPS) systems, MKP X2 capacitors are mainly used in AC input and EMI suppression circuits to reduce electrical noise and absorb voltage transients.
By using metallized polypropylene (MKP) film dielectric, MKP X2 capacitors deliver low loss performance, high insulation resistance, and stable capacitance under fluctuating AC conditions.
They play a critical role in improving system stability and protecting downstream electronic components in UPS power architectures.
Their compact structure and safety-certified design make them suitable for both single-phase and multi-phase UPS systems.

FAQ
1. Q:What is the principle of explosion-proof safety film capacitor?
A:The metallized electrodes adopt tiny fuses structure. If there is any failure during capacitor operation, the power supply is automatically cut off by disconnecting the micro-fuse. In this way, the failure can be prevented and self-safety protection realized.
2. Q:What’s meaning of P0(S0) and P2(S3) in the EVA capacitor?
A:P0(S0) and P2(S3) are refer to the class of safety protection. P0(S0) means non-explosion-proof. P2(S3) means explosion-proof.
3. Q:Common Installation Methods of Fan Capacitor
A:According to customers’ different installation methods on products, EVA-capacitor can provide the following capacitor styles. EVA-ac motor capacitors are used for starting, running and adjusting speed. EVA-Capacitor are widely applied in table tans, floor fans, ceiling fans, wall fans, luxury ceiling fans, exhaust fans, extractor fans, heater, smash paper machine, turbine, dehumidifier, etc.
Noted: Since the capacitor is made of plastic material, improper installation of the capacitor can cause the plastic ear to break. Therefore, the customer should pay attention to the URYU, screw, hole position to maintain vertical state during the fan capacitor installation.
4. What capacitance tolerances are available?
A:Tolerance on rated capacitance determines its application. Common values are ±5%（J）,±10%（K0）, ±20%（M）.
