Description
MICROMAX POWER SUPPLY BOARD
MODEL NUMBER
43E9999UHD
The image displays a power supply board, which is a crucial component in electronic devices like televisions, responsible for converting incoming AC power into various DC voltages required by the device's other circuits.
Key details visible on the board:
Primary Side:
This section, labeled "Primary," handles the high-voltage AC input from the mains power. It includes components like the main input connector, fuses (indicated by "CAUTION FOR CONTINUED PROTECTION AGAINST RISK OF FIRE REPLACE ONLY WITH SAME TYPE AND RATING OF FUSE"), large capacitors, and the primary winding of the main transformer.
Secondary Side:
Labeled "Secondary," this section deals with the lower DC voltages generated after rectification and regulation from the primary side. It contains components such as output capacitors, diodes, and connectors for delivering power to other parts of the device.
Transformers and Inductors:
Several yellow-taped transformers and copper-wound inductors are visible, indicating voltage conversion and filtering stages.
Capacitors:
Various electrolytic and ceramic capacitors are present, used for filtering, smoothing, and energy storage.
Heat Sinks:
A prominent black heat sink on the primary side and a smaller silver heat sink on the secondary side are present, indicating the presence of power transistors or ICs that dissipate heat during operation.
Connectors and Mountings:
The board features various connectors for input power and output to other boards, as well as mounting holes for securing it within a device.
Labels and Markings:
The board includes numerous labels for components (e.g., C301, R210, D501), test points, and safety warnings, aiding in identification and troubleshooting.
