FANAL DSL7-10 Analog output card

The predominant source of transformer sound is the core. The core sound depends on the flux density in the laminations and the magnetic properties of the core steel. The low-frequency and tonal nature. It occurs at twice the power frequency. Magnetic forces within the core will create vibration and sound. Load sound is the sound emitted by a loaded transformer in addition to its no-load sound. It is caused by electromagnetic forces resulting from leakage fields. The load sound is proportional to the fourth power of the current. The sources of this sound are the vibration of the tank walls, magnetic shields, and the windings.

Our products

A company specializes in the sales of module spare parts of global famous brands (DCS system) (robot system) (large servo control system). The company's products include distributed control system (DCS), programmable controller (PLC), MOTOROLA MVME industrial module, industrial control communication converter (Anybus), remote output/input module (RTU), industrial computer (IPC), industrial low screen screen (IPC) HMI SCSI (50, 68, 80Pin) AnyBus (Gateway) has become a global sales enterprise of industrial automation spare parts and components

The core and winding sound dominates the intermediate freq.

 range between 100 and 600 Hz. Sound produced by the cooling fans ( aerodynamic and motor/bearing sound ) is usually broad band in nature. Factors that affect the total fan sound output, include type speed, blade design, number of fans, and the arrengement of radiators. Pump sound is normally not significant if the fans are running, although low frequency sound may be present. The definitions have been given in IEC 60076 – 10.
