PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The GW-GSP100W-48 is designed for systems requiring a regulated 48V DC supply with compact dimensions and fanless operation. Its active PFC, dual isolated outputs, screw-terminal connection, and wide operating-temperature range make it suitable for telecom, networking, remote infrastructure, and distributed power applications. For this 100.8W capacity, commissioning should verify grounding, input protection, output stability, and the response of any redundant or hot-swap control logic.

Plan the GW-GSP100W-48 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-48 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.

DEPLOYMENT SCENARIOS

Where GW-GSP100W-48 fits best.

The GW-GSP100W-48 is designed for systems requiring a regulated 48V DC supply with compact dimensions and fanless operation. Its active PFC, dual isolated outputs, screw-terminal connection, and wide operating-temperature range make it suitable for telecom, networking, remote infrastructure, and distributed power applications.

Deployment Scenario Application Description
Telecom Access Equipment Powers access nodes, transmission interfaces, radio controllers, and compact telecom electronics
Industrial Ethernet Systems Supports managed switches, industrial gateways, protocol converters, and network-control devices
Remote Communication Cabinets Supplies stable power to roadside communication units, field terminals, and remote infrastructure electronics
Distributed 48V Platforms Functions as a local AC-DC source for equipment distributing regulated 48V power to downstream modules
Monitoring and Data Systems Powers remote data-acquisition devices, supervision controllers, and communication-enabled monitoring equipment
Dual-Output Electronic Systems Supports equipment requiring two electrically isolated 48V output paths within one integrated platform

POWER DESIGN

Reliability notes for continuous operation.

The GW-GSP100W-48 uses an active-PFC input stage and a single-ended flyback conversion topology to convert universal AC input into a regulated 48V 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 electrical 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 90% conversion efficiency
  • · Low-ripple and low-noise regulated 48V 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
