APC AP9627 – 2 U Rack Step‑Down Transformer 5 kVA

Overview :

The APC AP9627 is a rack‑mount step‑down transformer designed to convert higher‑voltage 208 VAC power feeds into standard 120 VAC outputs for IT equipment. It is deployed by data center power engineers and facilities teams where 120 V loads must be supported from 208 V utility or UPS distribution without separate dedicated 120 V circuits.

This unit accepts a 208 V input and provides 120 V output power at up to 5000 VA (5 kVA) capacity, supporting four NEMA L5‑20R receptacles for device connections. It includes rack mounting brackets and is built for continuous duty in controlled environments.

Physically the AP9627 occupies 2 U of standard 19″ rack space and features a twist‑lock NEMA L6‑30P input for secure connection to facility or UPS power feeds, making it suitable for rack power distribution and step‑down applications in data halls and network closets.

The transformer includes circuit breaker overload protection and typically operates with ~90 % efficiency at rated load, aligning with safety certifications such as UL 1778 and CSA.

In practical deployments AP9627 is used to feed 120 V loads in racks where only 208 V sources are present, such as behind a UPS or PDU; it should not be used in environments lacking proper ventilation or beyond its rated current and power limits
