50A High Current EMI Power Filter VIP5-4AG5-50-S(30004) Suppress Common & Differential Mode Noise

Product Overview
VIP5-4AG5-50-S is an industrial grade three phase EMI power filter designed for heavy duty three phase power supply systems. Its rated voltage reaches 380 440VAC with a maximum rated current of 50A RMS and supports 50 60Hz mains frequency. It adopts a professional three phase LC filtering circuit to deliver excellent noise suppression performance. This filter comes with outstanding high voltage resistance and high insulation value, alongside reasonably controlled leakage current. It maintains stable operation in the temperature range from minus 25 degrees Celsius to 85 degrees Celsius. It effectively suppresses common mode and differential mode noise on three phase power cables, improves overall power quality and protects precision control circuits of high power industrial equipment to satisfy EMC certification standards.

Application Scope & Usage
This three phase EMI filter is built to eliminate electromagnetic interference transmitted over three phase AC power lines and stabilize the incoming power supply. It protects delicate electronic components from damage caused by power noise. It is widely applied in high power industrial automation machines, large scale power control units, industrial drive systems and other heavy duty equipment that has strict EMC requirements. It prevents unexpected equipment faults induced by power interference and ensures long term continuous and stable operation of industrial machinery under complicated electromagnetic surroundings.

 FAQ for Power Filters

Q1. What is common mode noise and differential mode noise? A1. Common mode noise refers to the noise signal that exists on all power lines relative to ground. Differential mode noise is the interference signal between two power lines. EMI power filters are designed to suppress both types of noise simultaneously to clean the power supply.

Q2. Can I connect multiple EMI filters in series for better filtering performance? A2. In theory series connection can increase noise attenuation, but it may bring extra impedance and voltage drop. It also raises the overall cost and volume. It is better to select one proper filter model rather than simply connecting filters in series.

Q3. What is insertion loss of an EMI filter? A3. Insertion loss indicates the noise reduction capability of a filter. It measures how many decibels of noise will be reduced after installing the filter. Higher insertion loss means stronger ability to block high frequency electromagnetic interference.

Q4. What risks will high leakage current bring to the whole machine? A4. Excessive leakage current may trigger leakage protection devices such as residual current circuit breakers and cause unexpected power cut. It also increases the risk of electric shock for operators. Users should pick filters with leakage current matching their product application.

Q5. Does the power filter affect the power factor of the equipment? A5. Standard AC EMI filters have limited influence on power factor under rated working conditions. If you need to adjust power factor separately, you should add dedicated power factor correction modules instead of relying on the EMI filter.
