APC Smart-ups SRT 5KVA PDU 208V (4) L6-20 - SRT004

APC by Schneider Electric SRT004 Basic PDU 5000VA 208V 4-Outlet

Overview

The APC by Schneider Electric SRT004 is a basic power distribution unit designed to pair with compatible Smart-UPS SRT 5KVA systems operating at 208V. It provides four NEMA L6-20R receptacles, distributing up to 5000VA of UPS-backed power to connected equipment — making it a straightforward expansion option for rack environments where additional 208V outlets are needed without adding a separate PDU chassis. The SRT004 is compact at 121mm wide × 51mm deep × 190mm tall, so it fits tightly in configurations where panel space is limited.

Key Features

• Four NEMA L6-20R Outlets: L6-20R is the correct connector for 208V 20A circuits — standard in data center and AV/telecom rack environments. Having four independently accessible receptacles means you can distribute load across multiple devices without a separate strip or adapter.
• 5000VA Load Capacity: Matched to the SRT 5KVA platform, the SRT004 won't be the bottleneck in your power chain. At 208V, 5000VA translates to roughly 24A of available current — enough headroom for a dense rack of network or security appliances.
• 208V Nominal Input: Designed specifically for 208V feeds, not 120V. This matters at installation — confirm your feed voltage before ordering. Plugging into a 120V circuit will not work as intended.
• Compact Form Factor: At 121 × 51 × 190mm, the SRT004 mounts or positions cleanly alongside the SRT UPS without consuming significant additional rack or floor space.
• REACH and RoHS Compliant: Meets EU chemical and hazardous-substance standards. Mercury-free construction. Relevant for deployments with sustainability reporting requirements or regulated environments.

Frequently Asked Questions

Q: What UPS is the SRT004 designed to work with?

A: The SRT004 is designed for use with APC Smart-UPS SRT 5KVA systems operating at 208V. Verify compatibility with your specific SRT model before purchasing.

Q: What outlet type does the SRT004 provide?

A: The SRT004 provides four NEMA L6-20R receptacles, which are the standard 208V 20A locking outlets used in data center and commercial rack environments.

Q: Is the SRT004 a managed or monitored PDU?

A: No — the SRT004 is a basic PDU. It does not include network management, outlet-level switching, or power monitoring capabilities.

Q: Is the SRT004 RoHS compliant?

A: Yes. The SRT004 carries both REACH and RoHS compliance certifications and is mercury-free.

Q: What are the physical dimensions of the SRT004?

A: The unit measures 121mm wide × 51mm deep × 190mm tall and ships in a package weighing approximately 1.36 kg (3 lbs).

The SRT004 is a purpose-built outlet expansion module for the APC Smart-UPS SRT 5KVA 208V platform. If you're running an SRT5KXLT or similar 208V SRT chassis and need more L6-20R receptacles without adding a second UPS or a standalone managed PDU, this is the direct-attach solution. The four-outlet count is modest — plan your load distribution accordingly before committing to this unit versus a higher-capacity expansion option.

Technical Highlights:

• 5000VA Load Rating: Matched to the SRT 5KVA host — at 208V that's approximately 24A available across all four outlets combined. Don't treat each outlet as independently rated to 20A simultaneously.
• NEMA L6-20R Outlets: Locking 208V receptacles — the right fit for 208V-rated server and network equipment. Confirm your connected devices use L6-20 plugs or have compatible cords before installation.
• Basic PDU Classification: No metering, no switching, no network port. Power flows through passively. If you need outlet-level control or remote monitoring, this unit won't provide it — look at APC's AP-series managed PDUs instead.

Deployment Considerations:

• This unit is designed to work with a specific APC SRT host UPS — it is not a standalone PDU and should not be treated as one. Confirm physical and electrical compatibility with your exact SRT chassis model before ordering.
• With only four outlets and no load management features, the SRT004 is best suited for small, stable equipment groups where outlet count — not intelligence — is the gap you're filling.

The SRT004 fits cleanest in a dedicated AV control room, security head-end rack, or compact server closet where a 208V SRT UPS is already deployed and you need a handful of additional locking outlets without the cost or complexity of a managed PDU layer.
