Server Technology STV-FB636A-532P6/B 0U Switched Rack PDU

The Server Technology STV-FB636A-532P6/B is a 0U vertical switched power distribution unit built for three-phase data center racks that need per-outlet control across a large, mixed-connector load. With 36 total outlets — 24x IEC 60320 C13 and 12x IEC 60320 C19 arranged in alternating phase HDOT layout — this PRO2 Switched POPS unit is sized for dense server and network equipment racks where you're mixing standard servers, switches, and higher-draw devices like blade chassis or storage arrays on a single strip.

Overview

This is a Primary PRO2 Switched unit, meaning it's designed as the primary distribution strip in an A/B redundant power setup, or as a standalone switched strip where remote outlet control matters more than metering granularity alone. The STV-FB636A-532P6/B pulls 400/415V AC three-phase input through an IEC 60309 3P+N+PE connector rated for 32A input current, delivering a total power capacity of 22.9 kW per unit — enough headroom for a fully populated 42U rack running mixed 1U/2U servers plus a couple of higher-draw network appliances.

Key Features

• 36 total outlets (24x C13 + 12x C19): covers standard server power cords (C13) and higher-current devices like switches and blade enclosures (C19) from one strip — no need to run a second PDU for mixed-load racks.
• HDOT alternate phase outlet sequencing: outlets are arranged so adjacent sockets pull from different phases, which balances load across the three-phase input and reduces the chance of overloading a single phase when techs plug in equipment without checking a phase map.
• 22.9 kW total power capacity: gives you real headroom for a densely populated rack — plan your actual load against this ceiling rather than guessing, since exceeding it trips the input breaker.
• 32A input current at 400/415V 3-phase: matches standard European and international three-phase data center feeds, and the higher voltage means lower current draw per kW delivered compared to single-phase 208V setups.
• 0U vertical rackmount, 68.9" height: mounts in the rear rack channel without consuming any horizontal U space — critical when every 1U counts for compute or network gear, not power infrastructure.
• Switched (POPS) outlet control: per-outlet switching lets you remotely power-cycle a hung server or network device without a physical trip to the rack, and lets you sequence equipment power-up to avoid inrush current spikes on a shared circuit.
• 13.1 ft input cord length: reaches from a rack-mounted PDU position back to overhead or under-floor power whips without requiring an extension, simplifying cable management in a raised-floor data hall.
• 50/60 Hz frequency support: works on both North American 60Hz and international 50Hz power infrastructure, useful if this unit is standardized across a multi-region deployment.
• 230V AC output per outlet: matches the standard IEC voltage most rack-mount servers, switches, and storage controllers expect from their C13/C19 power inputs.

Integration & Compatibility

The STV-FB636A-532P6/B fits into the same PRO2 Switched POPS family used across Server Technology power distribution units, so racks already standardized on PRO2 switched or metered strips can add this unit without introducing a new management interface. As a 0U vertical unit at 2.17" wide and 2.95" deep, it mounts in the rear rack channel alongside cable management arms without competing for front-of-rack space. Pair it with a compatible rack-mount power infrastructure plan and appropriately rated network switches when building out a full rack power and connectivity map — and review a PoE and power planning guide before finalizing outlet-to-device assignments across a multi-rack deployment.

The STV-FB636A-532P6/B is one of the higher-outlet-count switched strips I spec for mixed-equipment racks — 36 total outlets on one 0U unit means you're rarely running out of drops before you run out of rack space.

Technical Highlights:

• 24x C13 + 12x C19 outlet mix: covers the bulk of standard 1U/2U server power cords (C13) plus higher-draw C19 devices like blade chassis and core switches, without needing a second strip for the heavy stuff.
• 22.9 kW total capacity at 32A/400-415V 3-phase: that's real capacity for a fully loaded rack — I check actual nameplate draw against this ceiling before final outlet assignment, not just estimated load.
• HDOT alternate phase sequencing: outlets alternate phases down the strip, so a tech plugging in equipment left to right naturally balances the three-phase load instead of stacking it all on one leg.

Deployment Considerations:

• At 68.9" tall this is a full-height 0U vertical unit — measure your rear rack channel clearance before ordering, especially in racks already running cable management arms or a second PDU.
• The 32A/three-phase input means you need 400/415V 3-phase infrastructure at the rack position — this isn't a drop-in replacement for a 208V single-phase strip, so confirm your facility's power plan before specifying.

This is the right call for a data center rack standardizing on Server Technology's switched PRO2 platform and running a mixed C13/C19 load — think a colo cage with core switches, blade servers, and standard 1U compute all sharing one three-phase circuit.
