GW-NHP350SW-5 300W AC-DC Power Supply

PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The GW-NHP350SW-5 is designed for equipment that requires a stable 5V rail with substantial current capacity. Its slim profile, wide input range, fanless cooling, and high-current screw-terminal output make it suitable for integrated electronic systems operating in compact or noise-sensitive environments. For this 300W capacity, 5Vdc output, backplane pinout, control signaling, and mechanical retention should be checked together before the unit is approved for production use. Installation planning should account for ambient temperature, pressure drop, service access, and the electrical limits of the surrounding platform. System validation should cover standby behavior, load transitions, protection recovery, and monitoring compatibility under expected operating conditions. Allow practical headroom for startup demand and transient loads, while keeping intake and exhaust paths clear throughout continuous operation. Record the approved operating limits and service checkpoints so future replacements can be qualified against the same baseline.

Plan the GW-NHP350SW-5 output wiring around the actual current demand: keep conductors short, use low-resistance terminations, separate power paths from sensitive signal wiring, and preserve access for retightening and inspection. Arrange the enclosure so heat from neighboring components cannot collect around the supply or its connection points.

Qualify the GW-NHP350SW-5 at several load levels, measuring voltage at both the supply terminals and the equipment input rather than relying only on no-load readings. Record cable drop, connector temperature, and enclosure temperature as baseline values. Later maintenance checks can compare against this record to identify loose joints, rising contact resistance, or deteriorating heat dissipation before they interrupt service.

CORE ADVANTAGES

300W 5V 60A Slim AC/DC Power Supply for Embedded Computing, Storage Backplanes, LED Control, and Automated Test Systems

The GW-NHP350SW-5 delivers a regulated 5V output at up to 60A, providing 300W of rated output power. It is designed for low-voltage, high-current electronic loads such as embedded computing boards, storage backplanes, LED control systems, digital processing equipment, and automated test platforms.

High-Current 5V DC Output

Ultra-Slim 26 mm Enclosed Design

With compact dimensions of 220 × 62 × 26 mm, the power supply is suitable for narrow chassis, slim equipment compartments, and space-constrained industrial enclosures. Its elongated metal housing provides mechanical protection while supporting efficient integration into compact systems.

Universal AC and High-Voltage DC Input

The unit supports a wide 90–264Vac input range and 127–370Vdc input. This allows it to operate across different regional power grids and selected high-voltage DC distribution environments, while built-in active PFC improves input current quality.

Fanless Natural Convection Cooling

The GW-NHP350SW-5 uses free-air convection cooling without an integrated fan. The fanless design reduces acoustic noise, mechanical wear, dust intake, and maintenance requirements, making it suitable for continuously operating electronic equipment.

Semi-Potted Construction for Environmental Durability

Its semi-potted internal design improves resistance to vibration, humidity, dust, and environmental stress. This construction supports reliable deployment in industrial control equipment, embedded systems, laboratory platforms, and other demanding installations.

Comprehensive Protection and Optional Monitoring

The power supply incorporates output short-circuit, overcurrent, overvoltage, and overtemperature protection functions. Optional DC OK signaling and redundant operating functions can also support power-status monitoring and higher-availability system architectures.
