The SAM ELECTRONICS NG3028G202 AS10 Power Supply PCB is a crucial printed circuit board designed for use within SAM Electronics (now typically part of Wartsila Voyage) marine systems. As a power supply unit, its primary function is to convert and regulate incoming electrical power to the precise voltage and current levels required by other electronic components and modules within the host system. This ensures stable and clean power delivery, which is essential for the reliable operation of sensitive navigation, automation, or communication equipment. As a replacement or spare part, the NG3028G202 AS10 PCB is vital for maintaining the continuous and correct functioning of the larger SAM Electronics system it supports.
Functional Specifications:
- Primary Purpose: To convert and regulate electrical power from a primary source into stable, usable DC voltages required by various sub-systems and components within the larger SAM Electronics equipment (e.g., navigation systems, automation systems, display units, communication equipment).
Technical Specification
- Input Voltage Range:
- Given it’s for marine use, it would typically accept standard shipboard power, which can vary. Common inputs might be:
- DC: 24V DC (nominal, with a wide tolerance for battery fluctuations, e.g., 18V-32V DC).
- AC: If it’s an AC-DC power supply, it might accept 110V/220V AC (50/60Hz).
- Output Voltages: Provides multiple, regulated DC output voltages specific to the needs of the system it powers. Common output voltages might include:
- +5V DC (for logic circuits)
- +12V DC (for various modules, fans, displays)
- -12V DC (for analog circuits, if required)
- Other specific voltages as needed by the host system.
- Power Output Capacity: Rated for a specific total power output (e.g., in Watts) to adequately supply all connected loads.
- Regulation: Provides highly regulated and stable output voltages despite fluctuations in input voltage or load changes.
- Protection Features: Likely incorporates various protection mechanisms crucial for marine environments:
- Over-voltage protection (OVP): Protects connected loads from excessive voltage.
- Over-current protection (OCP): Protects the power supply and loads from excessive current draw.
- Short-circuit protection (SCP): Prevents damage in case of a short.
- Over-temperature protection (OTP): Shuts down if internal temperature becomes too high.
- Reverse polarity protection (for DC inputs): Prevents damage if power is connected incorrectly.
- Filtering: Incorporates filtering to minimize electrical noise (EMI/RFI) on both input and output lines, crucial for sensitive marine electronics.
System Integration & Compatibility:
- Manufacturer: SAM Electronics (part of Wartsila Voyage).
- Application: Integral part of a specific SAM Electronics marine system (e.g., radar, integrated bridge system, automation system). The “AS10” might refer to a specific system or series.
- Role: Essential replacement or spare part to ensure the continuous and correct power delivery to the system’s components.
Physical Specifications (Inferred):
- Form Factor: Printed Circuit Board (PCB), designed to fit a specific enclosure or rack within the host SAM Electronics equipment.
- Connectors: Features input power terminals/connectors and multiple output connectors/pins for distributing power to other boards/modules.
