Aiphone IS-PU-UL 48V DC Power Supply
Overview
The IS-PU-UL is a UL-listed 48V DC power supply designed to support Aiphone intercom systems. It converts standard 100–240V AC input (50/60Hz) to regulated 48V DC output at 2.1A, delivering 120W of stable power for multi-unit installations. The compact design accommodates wall, ceiling, or standard 19-inch rack mounting (2U profile with IS-RACK adapter), making it suitable for both distributed indoor deployments and centralized equipment rooms.
Compatibility
The IS-PU-UL integrates with Aiphone master stations (NIM-20B, NIM-40B) and sub-station networks (NI-BA, NI-JA, NI-LB) requiring 48V DC feed. One power supply is required per IS Control Unit. Configurable mounting supports flexible installation in lobbies, corridors, equipment racks, and control centers.
