ATEN 30A 8-OUTLET 1U Outlet-metered & Switched (110V-230V) - PG6308B

ATEN PG6308B 30A 8-Outlet 1U Outlet-Metered and Switched Rack PDU

Overview

The ATEN PG6308B is a 1U rack-mount power distribution unit designed for data center and server room environments where per-outlet power metering and remote switching are operational requirements, not optional features. Built for 110V–230V operation with a 30A NEMA L6-30P input via a 3-meter power cord, the PG6308B gives infrastructure teams the ability to monitor load and remotely cycle individual outlets without a technician on-site — a meaningful capability in distributed rack deployments or remote colocation environments.

This unit sits in the middle of ATEN's 1U outlet-metered and switched PDU family alongside the PG6308A (NEMA L5-30P, North American 120V focus) and the PG6308G (IEC 60309 32A, international deployments). If your rack infrastructure runs on 208V circuits with L6-30P whips — the standard in most US data centers and larger server rooms — the PG6308B is the correct variant to specify.

Key Features

• 1% Metering Accuracy: Power measurement at ±1% accuracy means the load readings you see in the management interface are reliable enough to use for capacity planning and billing chargebacks — not just directional estimates. Guessing at rack load with ±10% accuracy tools leads to either over-provisioning circuits or unexpected trips; 1% removes that ambiguity.
• Per-Outlet Remote Switching: Each of the 8 outlets can be individually powered on, off, or cycled remotely. For locked-down colocation environments or branch IT closets, this eliminates truck rolls for hung servers or frozen network appliances — remote reboot without physical access is the operational value proposition here.
• 30A NEMA L6-30P Input with 3-Meter Cord: The included 3-meter cord with SR (strain relief) termination and NEMA L6-30P plug connects directly to standard 208V/30A PDU whips in most US data centers. The cord length is long enough to reach overhead busway or floor-level power strips without an extension, which matters in constrained rack environments.
• 110V–230V Input Range: Wide input voltage tolerance means the same unit works across North American 208V circuits and international 230V mains — useful if your organization standardizes equipment lists across geographies or needs a fallback deployment option without respecifying hardware.
• 1U Rack Form Factor: A single rack unit footprint keeps power infrastructure overhead minimal. In high-density deployments where every U matters, a 1U PDU that delivers 8 individually controlled outlets is efficient use of vertical space compared to multi-U alternatives.
• 0–80% RH Non-Condensing Humidity Rating: The operating and storage humidity envelope covers typical controlled data center environments. This is not rated for outdoor or high-humidity industrial use — plan accordingly if the installation site is not climate-controlled.
• UL and PSE Safety Certification: UL listing is the baseline safety certification required for most US enterprise procurement and insurance compliance. PSE certification covers Japanese market requirements. Both are present on the PG6308B, satisfying procurement checklists for facilities that require listed equipment.
• Firmware Upgrade Supported: The unit supports field firmware upgrades — the current release is v1.0.097 (released 2026-05-05). This means security patches and feature updates can be pushed remotely without replacing hardware, which matters for long-lifecycle data center assets.

Integration and Compatibility

The PG6308B is part of ATEN's outlet-metered switched rack PDU line. When specifying across a multi-rack deployment, note that the PG6308A (L5-30P) and PG6308G (IEC 60309 32A) share the same firmware image (PG8-1U-v1.0.097.zip), meaning centralized firmware management across mixed-variant deployments is straightforward. For organizations building out ATEN data center infrastructure, the PG6308B integrates naturally into ATEN's broader KVM and power management ecosystem. Pair with a managed network switch for in-band management access to the PDU's control interface. For comprehensive rack power planning, review the PDU selection guide to match circuit type, amperage, and outlet count to your rack load profile before specifying. If your facility uses overhead busway rather than floor-level power distribution, verify whip length against the 3-meter cord — in some high-ceiling data halls, a longer cord or local extension may be required.

Frequently Asked Questions

Q: What is the input plug type on the PG6308B?

A: The PG6308B ships with a 3-meter power cord terminated in a NEMA L6-30P plug, rated for 30A and suited for 208V circuits common in US data centers. This is distinct from the PG6308A, which uses NEMA L5-30P (120V/30A).

Q: How accurate is the power metering on the PG6308B?

A: The PG6308B provides ±1% metering accuracy. That level of precision is sufficient for load monitoring, capacity planning, and usage-based chargeback billing.

Q: Can individual outlets be switched independently?

A: Yes. The PG6308B is an outlet-metered and switched PDU, meaning each of its 8 outlets can be individually powered on, off, or cycled remotely — enabling remote reboots without physical access.

Q: What safety certifications does the PG6308B carry?

A: The PG6308B carries UL and PSE safety certifications. UL is required for most US enterprise and colocation environments; PSE covers Japan market compliance.

Q: Can the firmware on the PG6308B be updated in the field?

A: Yes. ATEN supports firmware upgrades on the PG6308B. The current release is v1.0.097 (released 2026-05-05), available as PG8-1U-v1.0.097.zip.

Q: What is the operating humidity range for the PG6308B?

A: The PG6308B is rated for 0–80% relative humidity, non-condensing, for both operating and storage conditions. It is designed for climate-controlled indoor environments, not outdoor or high-humidity industrial settings.

The PG6308B is the variant I specify when a rack deployment is running 208V/30A circuits and the facility team needs reliable outlet-level metering — not ballpark load estimates. The ±1% accuracy spec is the differentiator: it means the numbers in your power management dashboard are trustworthy enough to feed into capacity planning spreadsheets and chargeback reports, not just a reference for whether the rack is 'roughly half loaded.'

Technical Highlights:

• NEMA L6-30P Input: The L6-30P plug is the right fit for 208V/30A circuits — the standard in most US colocation and enterprise data centers. Verify your facility's whip type before ordering; the PG6308A (L5-30P) is for 120V/30A, not this unit.
• ±1% Metering Accuracy: At 1% accuracy across 8 monitored outlets, load data is precise enough to catch creeping oversubscription before it trips a breaker — meaningful in high-density racks where headroom is tight.
• Field Firmware Upgrade: The shared firmware image (PG8-1U-v1.0.097.zip) covers the PG6308A, PG6308B, and PG6308G variants. In a multi-variant deployment, a single firmware management workflow handles all three — no per-variant processes needed.

Deployment Considerations:

• The 3-meter cord length works for standard floor-to-rack or overhead busway runs, but measure your specific installation — some high-ceiling data halls or raised-floor configurations may require a local cord extension or repositioned PDU whip.
• The 0–80% RH non-condensing humidity rating is appropriate for any properly conditioned server room, but this unit is not rated for unconditioned environments, industrial spaces, or any installation where condensation is a risk.

The PG6308B is a practical fit for colocation customers who need outlet-level remote switching and billing-grade metering on 208V circuits — specifically environments where after-hours remote reboot capability eliminates the cost of on-call dispatch for hung equipment.
