APC Symmetra PX 25KW Power Module 400/480V - SYPM25KD

APC by Schneider Electric SYPM25KD Symmetra PX 25kW Modular UPS Power Module

The APC by Schneider Electric SYPM25KD is a 25kW (25 kVA) hot-swappable power module designed for the Symmetra PX modular UPS platform, supporting 400/480V three-phase power environments. If you are scaling capacity in an existing Symmetra PX frame or replacing a failed module without taking the load offline, this is the correct part to source. The SYPM25KD slots directly into the Symmetra PX chassis, allowing incremental capacity expansion without over-provisioning from day one — a key advantage in data centers and critical facilities where load grows over time.

Key Features

• 25 kW / 25 kVA Output: Delivers a full 25 kilowatts of conditioned, protected power per module. In a Symmetra PX frame, multiple modules stack to reach the frame's maximum capacity — meaning you only buy and power what you need today, adding modules as load grows rather than purchasing oversized capacity upfront.
• 400/480V Three-Phase Design: Compatible with both 400V (international/European) and 480V (North American) three-phase distribution, making the SYPM25KD deployable across a broad range of facility electrical configurations without requiring separate SKUs for each region.
• 40–70 Hz Input Frequency Range: Accepts input frequencies across the full 40–70 Hz band, providing tolerance for generator-sourced power — relevant in facilities that run on backup generators where frequency stability may drift during load transitions.
• UL, cUL, CE, VDE Certified: Carries UL Listed and cUL Listed marks (US and Canadian market compliance), CE marking (EU), and VDE certification (German electrical safety standard) — a combination that satisfies procurement requirements across North American and European enterprise deployments without sourcing region-specific variants.
• RoHS 7b Exemption Compliance: Meets RoHS directive requirements (with documented 7b exemption for lead in high-melting-point solder alloys) — relevant for EU installations subject to environmental compliance documentation requirements.
• 0–40°C Operating Range: Rated for operation in environments from 0°C to 40°C (32°F to 104°F), covering standard data center and IDF/MDF room conditions. Storage is rated down to -15°C, which matters for logistics and pre-installation staging in cold climates.
• 0–95% Operating Humidity (Non-Condensing): The full 0–95% relative humidity operating range means this module tolerates less-controlled environments — useful in edge deployments, industrial facilities, or locations without precision air handling.

Integration and Compatibility

The SYPM25KD is engineered for the APC Symmetra PX modular UPS product family. Verify your Symmetra PX frame model and existing module configuration before ordering — the Symmetra PX line spans multiple frame sizes and generations, and power module compatibility is frame-specific. The module weighs approximately 48.2 kg (106 lbs) packaged, so plan for two-person installation or mechanical lift assist when installing at height in a rack or tall UPS frame. This is not a standalone UPS — it requires a compatible Symmetra PX chassis, battery modules, and associated bypass/distribution components to form a complete system.

Frequently Asked Questions

Q: Is the SYPM25KD a standalone UPS or does it require a chassis?

A: The SYPM25KD is a power module, not a standalone UPS. It requires installation into a compatible APC Symmetra PX UPS frame/chassis along with battery modules and system components to form a complete uninterruptible power supply system.

Q: What voltage configurations does the SYPM25KD support?

A: The SYPM25KD supports 400V and 480V three-phase input/output configurations, covering both international (400V) and North American (480V) electrical distribution standards.

Q: What certifications does the SYPM25KD carry?

A: The SYPM25KD is UL Listed, cUL Listed, CE marked, and VDE certified. It also complies with RoHS requirements under a 7b exemption.

Q: What is the input frequency range for the SYPM25KD?

A: The module accepts input frequencies from 40 Hz to 70 Hz, providing tolerance for generator power sources where frequency may not hold precisely at 50 or 60 Hz.

Q: How heavy is the SYPM25KD?

A: The packaged weight is 48.2 kg (approximately 106 lbs). Plan for two-person handling or mechanical lift assistance during installation.

Q: What are the operating temperature limits for the SYPM25KD?

A: Operating range is 0°C to 40°C (32°F to 104°F). Storage range is -15°C to 40°C (5°F to 104°F).

James Everett

The SYPM25KD is the incremental capacity building block for Symmetra PX three-phase UPS deployments. At 25 kW per module with a 40–70 Hz input frequency tolerance, it is the module I specify when a facility needs to start at partial load and scale capacity hot — without scheduling a maintenance window every time the IT team adds another compute rack.

Technical Highlights:

• 25 kW Output Capacity: Each module contributes a full 25 kilowatts to the frame's total capacity. In a multi-module Symmetra PX frame, adding SYPM25KD units linearly expands protected output — useful when phasing a data hall buildout across budget cycles.
• 40–70 Hz Input Tolerance: Most UPS modules are tuned for 50 or 60 Hz. The 40–70 Hz band on the SYPM25KD explicitly covers generator operation, where engine governor response can let frequency slip by several Hz during load steps — this range absorbs that without transfer to battery.
• Multi-Certification (UL/cUL/CE/VDE): A single SKU clears procurement hurdles in both North American and European facilities. Organizations running multinational data centers avoid managing separate regional part numbers for the same function.

Deployment Considerations:

• At 48.2 kg packaged (106 lbs), the SYPM25KD requires two-person installation or a mechanical assist — factor this into your maintenance access planning, especially in dense colocation environments where aisle space is restricted.
• This is a module, not a system. Confirm frame compatibility with your specific Symmetra PX chassis model before ordering — the Symmetra PX line spans multiple generations and not all power modules are interchangeable across frame revisions.

The SYPM25KD is the right specification for enterprise data centers and critical facilities running Symmetra PX three-phase infrastructure that need to add capacity incrementally — particularly in phased construction or retrofit scenarios where avoiding a full UPS replacement is a hard requirement.
