MPS Industries, Inc. is a manufacturer of custom and standard engineered magnetic components for OEMs in the telecom, medical, and aerospace sectors. We deliver technical depth in the design and production of video isolation transformers to eliminate signal degradation and ground loop “hum” in professional electronic systems. Our team focuses on maintaining the signal integrity required for high-stakes broadcast, security, and medical imaging applications.
Learn more about the technical advantages of custom video isolation transformers, how we eliminate common-mode noise, and our capabilities for matching specific impedance and bandwidth requirements.
Solving Ground Loop and Common Mode Noise Issues
Ground loops occur when multiple pieces of equipment in a video system are connected to different ground potentials, causing current to flow through the coaxial cable shield. This interference manifests as horizontal “hum bars” or rolling noise on the display. Our video isolation transformers break this electrical path by delivering galvanic isolation between the input and output stages of the circuit.
By utilizing custom video isolation transformers, you eliminate the path for these circulating currents without degrading the baseband or high-frequency video information. This isolation also protects vital hardware from common-mode noise and potential voltage surges that travel through the cabling infrastructure. We focus on the precision required to block interference while passing the primary video signal with minimal insertion loss.
Designing for High-Definition Video Bandwidth
Maintaining the fidelity of high-definition signals, such as HD-SDI or 4K video, requires transformers with extremely flat frequency response across a broad spectrum. We design our components to handle the high-speed data rates required for modern digital video without introducing jitter or group delay. Our manufacturing process ensures that each component maintains consistent performance across low-frequency sync signals and high-frequency color information.
Impedance Matching for Coaxial Cabling
Signal reflections occur when there is an impedance mismatch between the cable and the connected hardware, leading to ghosting or packet loss. Most professional video systems utilize 75-ohm coaxial cabling. We engineer our video isolation transformers to match these specific impedance requirements, preventing return loss and maximizing power transfer across the signal path. We also deliver solutions for 50-ohm or custom differential signals used in specialized telecom or medical equipment.
Applications in CCTV, Broadcast, and Medical Systems
Reliability and consistency are the primary concerns for our OEM partners in vital industries. We supply isolated signal solutions for several demanding applications:
- Broadcast engineering. Eliminating noise in master control rooms and live production trucks, where long cable runs are common.
- Security and CCTV. Stopping hum bars in surveillance systems for industrial facilities or municipal infrastructure.
- Medical imaging. Maintaining clear signals for diagnostic equipment while meeting strict medical safety standards like IEC 60601-1.
- Telecommunications. Delivering network reliability for satellite receivers and transceivers.
