APC by Schneider Electric APDU9970 Switched Zero-U Rack PDU
Overview
The APC by Schneider Electric APDU9970 is a switched, single-phase, zero-U vertical rack PDU built for data center and network closet environments where per-outlet power control is non-negotiable. With 24 managed outlets across C13 and C19 receptacles, a 30A IEC 60309 input plug, and a load capacity of 4,992 VA, this unit is engineered for high-density equipment racks running mixed server, storage, and networking loads. The vertical 0U form factor keeps it out of your equipment bays entirely — a meaningful advantage in fully populated racks where every rack unit counts.
The APDU9970 sits in the rack PDU category alongside APC's broader APC by Schneider Electric power management line, and it's the right call when your operations team needs remote outlet cycling without touching the physical rack.
Key Features
- 24 Managed Outlets (C13 + C19): The outlet mix matters in practice. C13 receptacles handle standard 1U/2U servers, switches, and 1U storage; C19 outlets accommodate high-draw devices like blade chassis, large UPS loads, or GPU servers pulling above 10A per feed. Having both on one PDU eliminates the need for add-on strips in mixed-load racks.
- Switched Per-Outlet Control: Individual outlet switching lets ops teams remotely power-cycle a hung server, sequence boot order on startup, or de-energize a specific slot for maintenance — all without dispatching someone to the rack. In co-lo or remote-edge scenarios, that remote cycle capability directly replaces a physical site visit.
- 30A / 4,992 VA Load Capacity: At 32A maximum current on a 200–240V single-phase feed, the APDU9970 delivers 4,992 VA of usable load capacity. Size your connected loads to the 80% derate rule (roughly 25.6A continuous) to stay within safe operating margins — the PDU's rated maximum is the absolute ceiling, not the design target.
- IEC 60309 Input Plug: The IEC 60309 (industrial-grade) input connector is standard in purpose-built data center floor infrastructure and most colocation environments. If you're in a retrofit space with NEMA L6-30 whips, verify your local feed before ordering — this PDU requires a matching IEC 60309 receptacle or a qualified adapter.
- Wide Input Voltage Range (200–240V): Accepts 200, 208, 220–240V single-phase at 50–60 Hz. This makes it deployable across North American 208V 3-phase infrastructure (single leg), European 230V environments, and international data halls without a dedicated SKU for each region.
- Zero-U Vertical Mounting: The 0U form factor mounts vertically inside the rack's side channel, preserving all 42U (or more) of your equipment mounting space. Pair this with a vertical cable management arm for a clean installation in open-frame or enclosed cabinets.
- -5°C to 45°C Operating Range: Covers standard data center cold-aisle temperatures comfortably, plus edge deployments in non-climate-controlled closets that run warmer. Storage range extends to -25°C / 65°C — no special handling required for warehouse staging or shipping.
- 0–95% Non-Condensing Operating Humidity: No meaningful restriction for conditioned data center environments. For edge sites in humid climates, verify that condensation risk is managed — the PDU handles the humidity band but is not sealed against condensation events.
- Altitude Rated to 3,048m Operating / 15,240m Non-Operating: The 10,000-ft operating ceiling covers high-altitude data centers (Denver at ~1,609m, Bogotá at ~2,600m) without derating. The non-operating altitude spec (50,000 ft) means air freight is a non-issue.
Integration & Compatibility
The APDU9970 integrates into APC network management infrastructure via the standard AP9600-series network management card bay found on APC 9000-series PDUs, enabling SNMP, HTTP/S, and Modbus TCP monitoring and control. This means it slots directly into existing APC EcoStruxure IT or Data Center Expert deployments without additional protocol translation. For environments running a mixed PDU estate, the device also supports standard SNMP MIBs that third-party DCIM platforms can consume.
When paired with an appropriately rated UPS upstream, the outlet-level switching becomes a load-shedding tool during capacity events — selectively de-energizing lower-priority loads before the UPS transfer switch triggers. This is a common deployment pattern in colocation and enterprise data halls running N+1 power topologies.
Frequently Asked Questions
Q: What input plug does the APDU9970 use, and do I need a special circuit?
A: The APDU9970 uses an IEC 60309 industrial input plug. You will need a compatible IEC 60309 receptacle on your PDU whip or power strip. This is standard in most purpose-built data center and colocation environments but may require a qualified electrician to install a matching outlet in retrofit spaces.
Q: What is the maximum load I should run on the APDU9970?
A: The PDU is rated for 32A maximum current and 4,992 VA load capacity. Per the NEC 80% continuous load rule, design your connected load for no more than approximately 25.6A continuous to avoid tripping the upstream breaker during normal operation.
Q: Can the APDU9970 be used in 208V three-phase data center infrastructure?
A: Yes. The APDU9970 accepts 200, 208, 220–240V single-phase at 50–60 Hz, making it compatible with a single leg of a 208V three-phase feed as commonly deployed in North American data centers.
Q: Does the APDU9970 support remote per-outlet switching?
A: Yes. The APDU9970 is a switched PDU, meaning each outlet can be individually powered on, off, or cycled remotely — through the integrated network management interface when an APC network management card is installed in the management bay.
Q: What outlet types are on the APDU9970?
A: The APDU9970 provides 24 AC outlets in a mix of IEC C13 and IEC C19 coupler types. C13 outlets suit standard servers and networking gear; C19 outlets handle higher-draw devices that require the larger locking connector.
Q: What is the operating temperature range of the APDU9970?
A: The APDU9970 operates from -5°C to 45°C (23°F to 113°F), covering typical data center cold-aisle and edge-closet environments. Storage range is -25°C to 65°C.
The APDU9970 is the unit I specify when a customer needs granular outlet-level control in a vertical 0U form factor and can't afford to dedicate rack-unit space to a horizontal PDU. The 4,992 VA load capacity at up to 32A on a 200–240V single-phase IEC 60309 feed covers the vast majority of high-density 1-rack deployments I see in enterprise and colocation environments.
Technical Highlights:
- 24-Outlet Mixed C13/C19 Layout: The C13/C19 combination on a single switched PDU eliminates the secondary strip you'd otherwise need for high-draw devices — cleaner cable path, one fewer power chain to manage.
- Wide Voltage Acceptance (200–240V, 50–60 Hz): A single SKU that runs on 208V North American three-phase legs or 230V European single-phase — useful for multi-region deployments where standardizing on one PDU model simplifies spares inventory.
- -5°C to 45°C Operating Range: The upper 45°C ceiling handles hot-aisle temperatures in non-optimized legacy data rooms and edge closets that run outside ASHRAE A2 recommendations — without derating or throttling.
Deployment Considerations:
- The IEC 60309 input is correct for purpose-built data halls but can be a friction point in retrofit spaces — confirm your floor PDU or busway has a matching 32A IEC 60309 receptacle before the unit ships, or budget for an electrician to terminate one.
- Switched PDU functionality requires a network management card installed in the management bay — the APDU9970 itself provides the outlet hardware, but remote switching and monitoring are not active without that card. Factor the NMC into your BOM.
The APDU9970 is the right specification for high-density colocation cabinets, enterprise server rooms running mixed 1U/blade chassis, and remote-edge deployments where a technician dispatch for a power cycle is cost-prohibitive. It is not the call for 120V NEMA environments or deployments where metering at the outlet level (rather than switching) is the primary requirement.
