Power line filter modules are devices that include the components necessary to suppress voltage or current transients on AC or DC power lines. 4-160903-0 is among the leading examples of such module in today’s leading industrial sector. This device features a double-choke power line filter along with decoupling capacitors, proofers and a transient suppressor. Through this powerful combination of components, 4-160903-0 presents low losses at rated power, excellent AC/DC isolation, and a very low profile.

The main application field for this module is in the industrial HVAC, residential building, and other energy-related control systems. Its highly efficient design allows use in a variety of applications, such as static frequency converters (FC), motor speed control systems, power rectifiers, rectified outputs, and various HVAC control systems.

Furthermore, 4-160903-0 is well suited to cooperate with precision AC/DC power conversion systems, guaranteeing the continuous operation of AC and DC circuits. The transient voltage suppressors integrated in the filter module are also beneficial for preventing damage to connected equipment caused by overvoltage and overcurrent transients.

The working principle of 4-160903-0 is based on a low-capacity circuit, capable of acting as a small line conditioner, where the differential mode filter consists of an inductor and standard 82nF capacitor. The common mode filter includes both basic voltage blocking filters, and common mode filter along with a pitch connected choke, that are responsible for protecting connected equipment from overvoltages, overcurrents and other transients. The device also adds extra protection with the help of high capacitance film capacitors and connected grounds. Visual inspection of the device reveals well-made construction with neat, clearly indicated signals.

To conclude, 4-160903-0 is an ideal solution for applications that require protection from AC/DC transients, available in both single and double sided versions. Its highly efficient design provides excellent AC/DC isolation, low losses at rated power, and helps increase the system reliability. Power line filter modules such as 4-160903-0 are often the best choice for harsh, industrial environments and residential buildings due to their cost efficiency, superior construction, and high levels of safety.
