PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The GW-GSP100W-5 is intended for systems requiring a stable, high-current 5V supply in a compact enclosed format. Its active PFC, natural cooling, dual isolated output design, and wide operating-temperature range make it suitable for embedded, industrial, display, and test-system integration. For this 75W capacity, 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.

Plan the GW-GSP100W-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-GSP100W-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.

POWER DESIGN

Reliability notes for continuous operation.

The GW-GSP100W-5 uses an active-PFC input stage and a single-ended flyback conversion topology to convert universal AC input into a regulated 5V DC output. Its high-current output capability supports low-voltage electronic loads, while the natural-convection design enables quiet, fanless operation.

  • The dual isolated DC output structure can support equipment architectures requiring electrical separation between output paths. Because the supplied data does not specify the individual current allocation of each isolated output, system designers should confirm channel-level loading requirements before final integration.
  • Key reliability features include:
  • · Active PFC with single-ended flyback conversion
  • · Dual isolated DC output architecture
  • · Natural-convection fanless cooling
  • · Low-ripple and low-noise regulated 5V output
  • · Adjustable output voltage with LED status indication
  • · Comprehensive SCP, OCP, OVP, and OTP protection
  • · 100% high-temperature burn-in and 5G vibration testing
  • · Conformal-coated PCB with operation support up to 5,000 meters
  • · Design aligned with IEC, EN, and UL 62368 safety requirements
