APC by Schneider Electric Symmetra PX 50KW Scalable to 100KW 208V with Startup NO - SY50K100F-NB

APC by Schneider Electric SY50K100F-NB Symmetra PX 50kW Scalable to 100kW 208V UPS

Overview

The APC by Schneider Electric SY50K100F-NB is the Symmetra PX 50kW frame configured to scale to 100kW at 208V — a modular, three-phase uninterruptible power system built for data centers, network operations centers, and large-scale IT infrastructure where power continuity is non-negotiable. The SY50K100F-NB variant ships without the factory startup service, making it the right procurement choice when your team handles commissioning in-house or through your own field service provider. The model is also commonly searched as SY50K100F NB.

The Symmetra PX platform is APC's enterprise three-phase UPS line, designed around field-swappable power and battery modules so capacity can grow with the load — starting at 50kW and expanding to the 100kW frame maximum without taking the system offline. This modularity is the core reason data center architects specify it: you buy for today's load and expand in place rather than forklift-replacing the entire UPS when the next server rack comes online.

Key Features

• 50kW to 100kW Scalable Capacity: Start at 50kW and add power modules to reach the 100kW frame ceiling — capacity additions happen without downtime, preserving uptime SLAs during phased build-outs.
• 208V Three-Phase Output: Matches the input voltage standard of high-density server and networking equipment in North American data centers, eliminating step-down transformer requirements.
• No-Startup (NB) Configuration: Ships without the factory startup service included — reduces upfront cost when commissioning will be performed by qualified on-site personnel or a third-party service provider already under contract.
• Operating Temperature Range 32°F to 113°F (0°C to 45°C): Covers standard data center ambient conditions; keep the room below 113°F to stay within the rated envelope and protect battery life.
• Humidity Tolerance 0–95% Non-Condensing: Handles typical controlled-environment humidity without issue; condensing moisture remains the watch-out in poorly climate-controlled wiring closets.
• 2-Year Manufacturer Warranty: APC's standard warranty on the Symmetra PX frame covers parts and labor for two years — verify service-level options with APC directly if you require on-site response time commitments beyond the base coverage.
• DB-9 Serial Interface: The 9-pin D-Sub male-to-female serial connector supports legacy UPS management and signaling integration for monitoring systems that use RS-232 communication — relevant when connecting to older BMS or DCIM platforms.

Frequently Asked Questions

Q: Does the SY50K100F-NB include factory startup service?

A: No. The NB suffix explicitly means no factory startup is included. This lowers the purchase price but requires you to arrange commissioning independently — either with your own qualified personnel or a contracted field service provider.

Q: What is the warranty on the SY50K100F-NB?

A: APC provides a 2-year manufacturer warranty on this unit. For extended coverage or specific on-site service-level agreements, contact APC directly.

Q: Can the SY50K100F-NB be expanded beyond 50kW after installation?

A: Yes. The frame is rated to scale to 100kW. Additional power modules can be installed in the field to increase capacity without replacing the UPS frame.

Q: What input voltage does the SY50K100F-NB require?

A: The SY50K100F-NB operates at 208V three-phase. Confirm your facility's distribution panel provides the correct feed before installation.

Q: What is the operating temperature range for this UPS?

A: The unit is rated for 32°F to 113°F (0°C to 45°C) ambient. Sustained operation above 113°F will shorten battery life and may trigger thermal derating.

James Everett

The SY50K100F-NB's defining value is its in-place scalability — you commission the frame at 50kW and expand to 100kW by sliding in additional power modules, with no scheduled downtime and no frame replacement. For data center teams managing phased capacity rollouts, that modularity directly reduces the cost and risk of each expansion event compared to a fixed-capacity UPS that has to be swapped out.

Technical Highlights:

• Scalable Architecture: The 50kW-to-100kW expansion path means you're not over-buying capacity on day one — start at the load you have and add modules as racks fill.
• 208V Three-Phase: Aligns with the standard distribution voltage for high-density North American data center equipment, avoiding the transformer overhead of 480V-fed alternatives at this power class.
• NB (No Startup) Variant: The cost delta between the startup and no-startup SKU is meaningful at this power class — only choose NB if you have documented commissioning capability on-site or a service contract already in place.

Deployment Considerations:

• The 2-year warranty is the base APC coverage — for mission-critical deployments, verify whether your organization requires an extended service agreement before procurement, not after installation.
• Operating temperature ceiling is 113°F: in warm aisle/cold aisle configurations, confirm the UPS placement stays in the cold aisle or a conditioned zone — battery thermal derating above this threshold is not recoverable through firmware.

The SY50K100F-NB fits best in phased data center builds where the load forecast is uncertain at deployment time and the team has the internal capability to commission a three-phase UPS without factory support — a common profile for enterprise IT infrastructure expansions and co-location buildouts.
