Server Technology C1S39CS-4PPD2T222 400V 3-Phase High-Density Rack PDU

The Server Technology C1S39CS-4PPD2T222 is a Smart PRO1 Master Pips V39 rack power distribution unit built for high-density data center cabinets running 400V 3-phase Wye power. If your rack is pulling more load than a standard single-phase strip can safely carry, this is the class of PDU built to handle it — 32A input current on a 400V 3ph Wye feed with a configurable high-density outlet layout for mixed server, switch, and storage loads in the same cabinet.

Overview

C1S39CS-4PPD2T222 is a Master unit, meaning it carries its own IE (Intelligent Ethernet) network interface for direct monitoring and control rather than relying on a companion Master elsewhere in the rack power chain. That matters for colocation and multi-tenant environments where each cabinet's power draw needs to be visible independently, without daisy-chaining monitoring back to a shared controller.

Key Features

• 400V 3-Phase Wye Input: Delivers three-phase power on a Wye (star) configuration, which gives you both phase-to-phase and phase-to-neutral voltage options at the outlet level — standard for European and high-density North American data center feeds where single-phase circuits run out of headroom.
• 32A Input Current: A 32A input rating supports considerably more connected load per PDU than the common 16A or 20A units, which means fewer PDUs per cabinet row and less circuit sprawl when you're populating racks with dense compute and storage.
• High-Density Configurable Outlets: The outlet bank is configurable rather than fixed, so the PDU can be specified to match the actual plug mix in a rack (a blend of server power supplies, network gear, and storage arrays) instead of forcing every device onto the same connector type.
• IE Network Interface: Built-in Intelligent Ethernet connectivity puts the PDU on the network for remote visibility — useful when the cabinet lives in a colo suite or a remote facility and someone needs to check load or power state without a truck roll.
• Master Unit Architecture (Pips V39): As a Master in the Pips product line, this unit anchors the monitoring and control layer for the rack's power chain, which is the piece you need in place before adding any linked units downstream.

Integration & Compatibility

Because the C1S39CS-4PPD2T222 (often searched as C1S39CS 4PPD2T222) runs on a 400V 3ph Wye input, confirm your data center's power distribution is provisioned for 400V 3-phase before ordering — this is not a drop-in replacement for a 208V or 120V single-phase strip. The IE interface is built for standard Ethernet-based monitoring integration, so plan a network drop to the cabinet if remote polling is part of your power management strategy. Pair it with matched rack rail hardware and confirm your PDU mounting has clearance for the outlet bank configuration ordered on this specific unit.

Karl Wilson

The C1S39CS-4PPD2T222 crosses my desk mostly in colo and enterprise data center quotes where the customer has already outgrown single-phase rack power. A 400V 3ph Wye feed at 32A is a meaningfully bigger power envelope than a typical 208V strip, and that's the whole point of specifying this unit.

Technical Highlights:

• 400V 3ph Wye, 32A input: Supports dense mixed-load cabinets — compute, switching, and storage — on one PDU instead of splitting the rack across multiple lower-amperage strips.
• High-density configurable outlets: Lets you spec the outlet bank to the actual gear going in the rack rather than adapting devices to fixed connectors.
• IE network interface: Puts this Master unit on the network directly for remote load monitoring, which matters when the cabinet isn't on your local floor.

Deployment Considerations:

• Verify your facility's power plant actually delivers 400V 3-phase Wye to the row before specifying this PDU — it's not interchangeable with a 208V single-phase feed.
• As a Master unit, confirm whether your rack power plan calls for additional linked units downstream, since the Master carries the monitoring intelligence for the chain.

This is the right call for a colo cabinet or enterprise data center row standardizing on 400V 3-phase distribution with a need for per-cabinet network visibility — not for a branch office running a single 208V circuit.
