PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The GW-GSP100W-27 is designed for equipment requiring a regulated 27V DC supply with compact installation dimensions and fanless operation. Its active PFC, dual isolated outputs, screw-terminal connection, and wide operating-temperature range make it suitable for communication, measurement, monitoring, and specialized electronic applications. For this 102.6W capacity, before integration, confirm the connector mapping, chassis clearance, and supported input conditions against the target power shelf. For long-term service, document fan inspection, connector seating, event-log review, and replacement procedures as part of the maintenance plan.

Plan the GW-GSP100W-27 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-27 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-27 uses an active-PFC input stage and a single-ended flyback conversion topology to convert universal AC input into a regulated 27V DC output. Its natural-convection cooling design eliminates the need for an integrated fan, helping reduce acoustic noise and mechanical maintenance requirements.

  • The dual isolated DC output structure supports systems requiring separation between output paths. Because the supplied information does not specify the individual current allocation for each isolated output, channel-level loading should be confirmed before final system integration.
  • Key reliability features include:
  • · Active PFC with single-ended flyback conversion
  • · Dual isolated DC output architecture
  • · Natural-convection fanless cooling
  • · Up to 88% conversion efficiency
  • · Low-ripple and low-noise regulated 27V 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
