Features:
- Converts wide-range AC or DC input power into multiple regulated DC outputs with ±1% voltage regulation.
- Uses large heat sinks together with extensive filtering components to enhance thermal performance and reduce electrical noise.
- Provides up to 150 W of power with high-current output capability and convenient rack installation features.
General Electric DS3800NPSE1E1G serves as the power distribution hub within the Mark IV control system. Stable low-voltage power is essential for analog and digital circuitry, and the board supplies multiple regulated outputs to support those functions. Broad input voltage compatibility allows flexible integration into various industrial installations.
Electrical performance is supported by a 150 W power rating and output capacities reaching 20 A on the +5 V rail and 2 A on the ±15 V rails. Numerous capacitors and filter inductors are arranged across the board to improve waveform quality and suppress unwanted noise. Such characteristics contribute to dependable operation in environments where electrical disturbances are common.
General Electric DS3800NPSE1E1G is also engineered with long-term reliability and serviceability in mind. Heat generated by power semiconductor devices is managed through two large metal heat sinks, helping maintain stable performance during continuous operation. Dedicated connectors and extractor clips allow technicians to install, remove, and service the board efficiently within Mark IV cabinets.
The DS3800NPSE1E1G General Electric Power Supply Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
