CyberPower SM020KAMFA Modular 3-Phase UPS System

Overview

The CyberPower SM020KAMFA is a 20kVA modular 3-phase UPS system designed for mission-critical surveillance infrastructures, data centers, and commercial facilities requiring configurable N+1 or N+N redundancy. Built on double-conversion topology, the SM020KAMFA delivers 208/120V or 220/127V three-phase input and output with 1.0 power factor — meaning no reactive power waste and predictable generator compatibility. The unit arrives in an 11U rack form factor measuring 19.1 x 23.9 x 30.5 inches and includes the RMCARD205 remote management card pre-installed, eliminating the need for post-delivery configuration. This is a genuinely modular system: power modules, batteries, and even the bypass path swap hot without shutdown.

Key Features

• 20kVA/20kW capacity with online double-conversion: Handles simultaneous 3-phase loads (NVRs, switches, access control, HVAC) without voltage sag or noise injection. Double-conversion means incoming AC is rectified, inverted back to AC through battery-backed electronics — no transfer switching, no momentary glitches when utility power wavers. That matters for storage-intensive surveillance systems where a failed write due to power dropout costs you a recorded incident.
• N+1 and N+N redundancy modes: Stack multiple SM020KAMFA units for fault tolerance. If one 20kVA module fails, the other assumes load without dropping a single frame. No surveillance blind spot, no manual failover. Configurable at install time — you're not locked into one redundancy strategy.
• Hot-swappable power modules and batteries (±120VDC nominal bus): Battery runs dry? Pull the old module, slide in a new one — system stays live. Same with power conversion modules. In a 24/7 surveillance environment where a facility manager may not be on-site during a battery replacement, this is the difference between a scheduled service window and an actual outage.
• 7-inch color LCD touchscreen with real-time status display: View input/output voltage, battery charge percentage, load watts per phase, temperature — all without SSH or a web browser. Useful when walking the data closet and you need to confirm UPS health in 10 seconds. Firmware is upgradable, so touchscreen behavior and metrics can improve post-purchase.
• RMCARD205 pre-installed for SNMP/Modbus/serial remote management: Monitor and manage from your NOC or security operations center. EPO (Emergency Power Off) function wired into building automation systems. PowerPanel Business software included — query UPS state, trigger graceful shutdown sequences, log battery cycle history for predictive replacement. No additional card purchase or integration delays.
• 93% efficiency in normal mode, >97.5% in ECO mode; 92.5% on battery backup: In a large surveillance deployment where the SM020KAMFA may run 8–12 hours per day covering battery charging, efficiency directly impacts electricity cost and heat load in the equipment closet. 93% normal mode means you lose ~1.4kW as heat for every 20kVA drawn — significant enough to affect CRAC sizing or fan cooling strategy.
• Configurable 208/120V or 220/127V 3-phase input/output: Matches your facility's grid standard without buying separate step-up/step-down transformers. Nominal ±120VDC bus voltage is industrial standard — interchangeable battery modules with other 120VDC UPS systems in your fleet.
• Operating range 0–40°C (32–104°F) with up to 95% humidity (non-condensing): Handles uninsulated server rooms, outdoor equipment shelters (if climate-controlled), and coastal facilities. Battery lifespan curves favor cooler environments — every 10°C above 25°C roughly halves battery service life, so the 40°C upper spec tells you this isn't designed for un-cooled attics or direct sun-facing closets.
• Hardwire terminal block output (L1, L2, L3, Neutral, Ground): No plug-and-play connectors — cabling is permanent and load-rated. Reduces intermittent contact issues common on large 3-phase systems. Professional installation expected; this isn't a consumer plug-in model.

Integration & Compatibility

The SM020KAMFA integrates via USB, serial RS232/RS485, Modbus TCP/RTU, and SNMP (via the RMCARD205). Connects to PowerPanel Business for Windows/Linux servers, or to building automation systems (BACnet, Modbus) for centralized facility monitoring. Generator-compatible: the system recognizes when running on genset power and manages battery charge accordingly. Expandable battery cabinet option for extended runtime beyond the base module — useful in facilities where 15–30 minutes of battery autonomy proves insufficient and you're willing to trade rack space for 2–4 hour hold-up time.

Redundancy and Scalability

For surveillance facilities that cannot tolerate a single UPS failure, the N+1 configuration allows two SM020KAMFA units to share the load, with automatic switchover if one unit degrades. Common practice in tier-2 and tier-3 data centers; redundant UPS pairs are cheaper than a single 40kVA unit and offer granular fault isolation.

Environmental and Standards Compliance

Meets cTUVus UL1778, CSA C22.2 No. 107.3-14, FCC Part 15 Subpart B Class A, IEC62040-2, and RoHS. These certifications confirm the unit is safe for commercial deployment in North America and complies with electromagnetic emissions standards — important if the facility houses sensitive instrumentation or broadcast equipment nearby.

Frequently Asked Questions

Q: What is the battery autonomy (runtime) on the SM020KAMFA?

A: Runtime depends on the battery module configuration and load level. Standard configurations typically deliver 5–15 minutes of full-load runtime. Extended runtime requires an optional expandable battery cabinet. Check the detailed technical specifications or contact the vendor for runtime curves at specific load percentages.

Q: Can I run the SM020KAMFA on generator power?

A: Yes. The system is generator-compatible and will manage battery charge and load balancing when utility power is offline. Confirm your generator's voltage regulation with the UPS input requirements (208/120V ±10% or 220/127V ±10%) before coupling.

Q: Does the SM020KAMFA support N+1 redundancy out of the box?

A: The SM020KAMFA is capable of N+1 and N+N redundancy, but redundancy is configured at installation. You will need two units and appropriate cabling/firmware settings. The system is not redundant with a single unit alone.

Q: What's the warranty on the SM020KAMFA?

A: CyberPower provides a 1-Year Limited Warranty on the SM020KAMFA covering manufacturing defects and component failures under normal operating conditions.

Q: Can I upgrade the RMCARD205 or replace it with a different management card?

A: The RMCARD205 is pre-installed and handles SNMP, Modbus, serial, and USB management. It is field-replaceable, but the SM020KAMFA is designed around this card. Consult the vendor or CyberPower documentation for compatibility with alternative remote management cards.

Q: What is the footprint and rack height of the SM020KAMFA?

A: The unit is 11U in rack height, 19.1 inches wide, 23.9 inches deep, and 30.5 inches tall. Confirm clearance in your rack before ordering, particularly for hot-swap battery module access from the front.

James Everett

I've deployed the SM020KAMFA in mid-tier surveillance facilities where a single UPS failure can't be tolerated, and the modular design is the real win here. You're not buying a sealed black box; every power module, every battery, and the bypass path come out hot. That means when a battery module ages out after 3–5 years, you swap it in 15 minutes without scheduling a facility shutdown. The SM020KAMFA handles this because it maintains a ±120VDC bus that stays live during component replacement — something you don't get with cheaper fixed-architecture units.

Technical Highlights:

• 20kVA with online double-conversion topology: Every microsecond of AC is regenerated through the battery-backed inverter chain. No transfer-switch chatter, no voltage sag to trigger edge device reboots. In a 24/7 surveillance environment where a glitch costs you hours of debugging, double-conversion is the standard that matters.
• N+1 redundancy architecture (configurable): Two SM020KAMFA units operate in parallel, sharing load equally. If one degrades, the surviving unit absorbs 100% of load without a hiccup. Common in colocation facilities and corporate security operations centers where a single failure triggers a post-incident review.
• 93% efficiency normal mode; 92.5% battery mode: For a 20kVA load running 10 hours a day, that 7% loss is roughly 1.4kW dissipated as heat. In a tight equipment closet, that's real cooling demand. The >97.5% ECO mode (lower online protection but useful for non-critical branches) keeps thermal load minimal if you're willing to trade off some transient immunity.
• RMCARD205 pre-installed; SNMP/Modbus/serial included: No integration delays. Hook it to your NOC, query real-time load per phase, and schedule graceful VMS shutdown if mains fail for more than 10 minutes. PowerPanel Business software logs every event — useful for predicting when a battery cabinet replacement will be needed.

Deployment Considerations:

• This is an 11U system in a standard 19-inch rack. Confirm you have the depth (30.5 inches) and clearance for front-facing hot-swap battery module access. In retrofit deployments, older 6-foot equipment racks can feel cramped with this unit plus cabling on both sides.
• Runtime on the base module is typically 5–15 minutes at full 20kVA load. If your facility needs 30+ minutes of hold-up time (not uncommon for facilities 30+ minutes away from the nearest data center), budget for an expandable battery cabinet. That's a separate purchase and adds significant rack footprint and weight.
• The 208/120V three-phase input is standard in North American commercial buildings, but verify your facility's actual grid voltage (some older buildings run 240V single-phase or oddball voltages). The SM020KAMFA is flexible, but reconfiguration requires CyberPower or a vendor technician on-site — not a firmware setting you flip yourself.

Position the SM020KAMFA where you need modular fault tolerance and long-term serviceability — regional data centers, corporate security operations centers with backup generator systems, and multi-site surveillance deployments where the same UPS architecture repeats across facilities. If your facility is a small remote site with a single 20kVA load and no redundancy requirement, a smaller fixed-architecture model may be more cost-effective.
