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).

Description
Within the Mark IV control system, General Electric DS3800NPSE1E1G provides regulated power for various control and monitoring functions. The board accepts a wide input range of 90–264 VAC or 24–48 VDC and generates stable +5 V, +15 V, and -15 V DC outputs. With a total power rating of 150 W, the board supports demanding industrial applications requiring reliable power conversion.

Power distribution is one of the major functions of DS3800NPSE1E1G. The +5 V output can deliver up to 20 A, while the ±15 V outputs provide up to 2 A. Voltage regulation accuracy of ±1% helps maintain stable operating conditions for sensitive analog and logic circuits throughout the control cabinet. Numerous capacitors and filter inductors are incorporated to smooth voltage waveforms and suppress ripple and high-frequency electrical noise commonly found in industrial environments.

General Electric DS3800NPSE1E1G also features a hardware layout intended for continuous operation. Two large metal heat sinks are mounted on key power semiconductor devices to improve heat dissipation under heavy loads and reduce the risk of voltage drift caused by excessive temperature. Dedicated two-pin and multi-pin connectors support high-current input and output connections, while extractor clips simplify installation and removal from the rack. The board operates within temperatures from 0°C to 60°C and humidity levels between 5% and 95% RH without condensation.
