PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The GW-GSP550W-15 is designed for systems requiring substantial current from a regulated 15V rail. Its active PFC, half-bridge LLC conversion, built-in fan, remote sensing, and high conversion efficiency support integration into precision electronic and industrial platforms. For this 549.9W capacity, allow practical headroom for startup demand and transient loads, while keeping intake and exhaust paths clear throughout continuous operation. Before integration, confirm the connector mapping, chassis clearance, and supported input conditions against the target power shelf.

Plan the GW-GSP550W-15 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-GSP550W-15 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.

POWER DESIGN

Reliability notes for continuous operation.

The GW-GSP550W-15 combines an active-PFC input stage with a half-bridge LLC conversion architecture to produce a regulated 15V output from a universal AC source. Because the output current can reach 36.66A, conductor resistance, terminal quality, connector selection, PCB copper capacity, and load-side voltage drop should be considered carefully during integration.

  • The remote-sensing function can compensate for voltage loss between the power supply and the connected equipment. Sense wires should be connected according to the system design and routed separately from high-current or high-noise wiring.
  • Key reliability features include:
  • · Active PFC with PF greater than 0.97 and half-bridge LLC conversion
  • · Universal 90–264Vac input compatibility
  • · Up to 93.5% conversion efficiency
  • · Built-in DC fan for forced-air cooling
  • · Remote ON/OFF control with remote voltage sensing
