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
