Altronix T2CSK7F10D 24VDC 10A Surveillance Power Supply with Battery Backup
Overview
The Altronix T2CSK7F10D is a 24VDC, 10-amp continuous-output power supply designed for commercial security installations where uninterrupted power delivery and battery backup are non-negotiable. Built into a steel enclosure measuring 27.25" x 21.5" x 6.5", it accepts 120VAC/60Hz input and draws a maximum of 4.5A from the line — giving you a clean, regulated DC rail to feed cameras, controllers, or other security peripherals across a single consolidated distribution point. The T2CSK7F10D supports a 12AH/12VDC battery, keeping your system running during brief outages without requiring a separate UPS infrastructure. For integrators working on Altronix power distribution systems, this unit fits within the broader Altronix power supply and access control line as a high-current output option.
Key Features
- 24VDC @ 10A Continuous Output: A full 10 amps available continuously — not peak — means you can confidently load this supply at or near its rated capacity without thermal throttling concerns. That's enough headroom to drive multiple 24V cameras or door controllers from a single unit without budgeting for derating.
- 120VAC / 60Hz Input, 4.5A Max Draw: Draws under 4.5A from a standard 15A branch circuit, leaving ample margin for co-located equipment on the same panel leg. No dedicated high-amperage circuit required for the input side.
- 12AH / 12VDC Battery Support: Integrated battery support for a 12AH sealed lead-acid battery means your downstream devices stay powered through short outages — relevant for access control panels and alarm systems where even a momentary dropout causes a nuisance alarm or door-fail event. Battery capacity is sized for several hours of standby depending on load.
- Steel Enclosure (27.25" x 21.5" x 6.5"): The all-steel cabinet provides physical protection for the transformer, regulation circuitry, and battery while satisfying NEC requirements for enclosing power-limited wiring. The depth of 6.5" accommodates the battery without extending the footprint unreasonably on a mechanical room wall.
- PTC (Positive Temperature Coefficient) Overcurrent Protection: PTC resettable protection means a shorted output load won't blow a fuse you have to replace in the field — the circuit self-resets once the fault clears. For multi-output distributions this is a meaningful maintenance advantage over fused alternatives.
- EFL (Electronic Fuse / Fault Limiter): Electronic fault limiting adds a second layer of output protection beyond the PTC, isolating faulted loads from healthy ones. In a multi-camera or multi-reader run, one shorted cable doesn't cascade.
- CE European Conformity: CE listing confirms the unit meets EU electromagnetic compatibility and low-voltage directive requirements — relevant for installations where equipment documentation must satisfy European compliance audits, even in US deployments subject to international facility standards.
- Operating Range 0°C to 49°C: Rated for environments up to 49°C (approximately 120°F), covering most mechanical rooms, utility closets, and indoor riser spaces without derated output. Storage temperature extends from -20°C to 70°C, so units can be warehoused in unheated spaces without concern.
- Relative Humidity Tolerance to 85% ±5%: Suitable for humid mechanical rooms and basement installations where condensation is a periodic concern — without requiring additional environmental conditioning of the enclosure.
Integration & Compatibility
The T2CSK7F10D outputs regulated 24VDC, which aligns with the operating voltage of a broad range of commercial security devices — including 24V AC/DC cameras, electromagnetic locks, electric strikes, and legacy alarm panels that accept 24V input. It is appropriate for integration into centralized surveillance and access control power distribution schemes where multiple devices share a common power bus. When designing multi-zone systems, pair with Altronix distribution modules or fused multi-output boards to subdivide the 10A rail across individual home-run device feeds. For larger deployments requiring higher aggregate current or additional battery capacity, consider stepping up within the Altronix product family to higher-amperage variants. Integrators building PoE-centric camera networks should note this is a direct 24VDC supply, not a PoE injector — it feeds 24V passive devices or non-PoE infrastructure, not IEEE 802.3-standard PoE cameras. Review your power planning and load calculations before committing to output distribution architecture.
Frequently Asked Questions
Q: What battery does the T2CSK7F10D support, and is it included?
A: The T2CSK7F10D is designed to support a 12AH/12VDC sealed lead-acid battery. Based on available evidence, the battery is not confirmed as included — verify at time of order and source a compatible 12AH/12V SLA battery separately if needed.
Q: Can the T2CSK7F10D power 24V PoE cameras?
A: No. This unit outputs regulated 24VDC on conventional terminals — it is not a PoE injector and does not comply with IEEE 802.3af/at/bt standards. It is suited for 24V passive devices, door hardware, and alarm peripherals, not IEEE PoE network cameras.
Q: What is the maximum ambient operating temperature for the T2CSK7F10D?
A: The unit is rated for 0°C to 49°C (approximately 32°F to 120°F) operating temperature, covering most indoor mechanical room and utility closet environments.
Q: Does the T2CSK7F10D include overcurrent protection?
A: Yes. It includes both PTC (positive temperature coefficient) resettable overcurrent protection and EFL (electronic fault limiting) for output fault isolation — no fuse replacement required after a shorted load clears.
Q: What are the enclosure dimensions of the T2CSK7F10D?
A: The steel enclosure measures 27.25" wide x 21.5" tall x 6.5" deep. Plan wall mounting clearance accordingly — the 6.5" depth accommodates the internal battery without additional external housing.
Q: Is the T2CSK7F10D CE listed?
A: Yes, the T2CSK7F10D carries CE European Conformity listing, confirming compliance with applicable EU electromagnetic compatibility and low-voltage directives.
The T2CSK7F10D is a unit I'd reach for when a job calls for a consolidated 24VDC distribution point with battery backup in a single steel cabinet — specifically because that 10A continuous output rating gives you honest headroom rather than a peak number that derates under sustained load. At 49.8 lbs with battery installed, this isn't a one-person hang, but the enclosure size (27.25" x 21.5" x 6.5") is proportional for a mechanical room wall mount serving a multi-reader or multi-camera 24V zone.
Technical Highlights:
- 10A Continuous Output @ 24VDC: Continuous — not peak — rating means you can run the output near full capacity without worrying about thermal derating over a multi-hour shift. That's the distinction that matters in 24/7 access control and surveillance environments.
- PTC + EFL Dual Fault Protection: The combination of resettable PTC overcurrent protection and electronic fault limiting isolates individual output faults without requiring fuse swaps. In a building with 10+ devices on a single supply, this protection stack prevents one bad cable from taking down the entire run.
- 12AH Battery Support: A 12AH SLA battery at a light-to-moderate load (2–4A) typically delivers 2–4 hours of backup runtime — enough to bridge most utility outages without a full UPS. The battery compartment is integrated into the 6.5"-deep enclosure, keeping the footprint compact.
Deployment Considerations:
- Verify input circuit availability before roughing in: the unit draws up to 4.5A from 120VAC/60Hz, so a standard 15A branch circuit supports it with margin — but confirm the panel leg isn't already loaded by HVAC or lighting in older buildings.
- The T2CSK7F10D is a 24VDC direct-wire supply, not a PoE source. If your camera or reader spec sheet calls for IEEE 802.3af/at power, this unit won't work without a passive injector — and passive injection on IEEE PoE devices is a compatibility risk.
This supply fits best in a commercial access control or hybrid camera/door-hardware installation where you want centralized 24VDC distribution with local battery backup — think a multi-door office floor or a warehouse entry cluster where the panel, readers, and a handful of 24V analog or IP cameras all terminate in the same IDF closet.
