POWER DESIGN

Reliability notes for continuous operation.

The GW-GSP100W-12 uses an active-PFC input stage and a single-ended flyback conversion topology to convert universal AC input into a regulated 12V 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. Since the supplied information does not state 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 86% conversion efficiency
Low-ripple and low-noise regulated 12V 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
