Altronix T3AXK77F16SDV 24VDC 10A Surveillance Power Supply with Battery Backup
Overview
The Altronix T3AXK77F16SDV is a 24VDC, 10A centralized power supply designed for international surveillance installations running on 220VAC mains. Built into a large-format steel enclosure (36.12" x 30.125" x 7.06"), it consolidates power distribution for multi-camera or access control deployments while providing integrated 12AH battery backup — keeping cameras live through a brief power outage without a separate UPS. The T3AXK77F16SDV carries CE European Conformity listing, making it the correct choice when code or customer requirements mandate CE-marked equipment in European or international markets.
If you're evaluating the broader Altronix power supply lineup, note that this model is specifically sized for 220VAC environments — it is not a dual-voltage unit and should not be connected to 120VAC infrastructure without a step-up transformer.
Key Features
- 24VDC / 10A Main Output: Delivers a stable regulated 24VDC bus at up to 10A — enough headroom to simultaneously power multiple IP cameras, PTZ drives, or door controllers from a single enclosure without voltage sag under load. A 1A auxiliary output provides a secondary circuit for supplemental devices such as door strikes or alarm panels, keeping auxiliary loads off the main camera bus.
- 220VAC / 50–60Hz Input with 6.5A Input Fuse: Accepts the 220VAC standard used across Europe, the Middle East, Asia, and Latin America. The 2.7A input draw and 6.5A/250V fuse are appropriately sized for the output load — verify that the local circuit breaker is rated accordingly before commissioning. The 50/60Hz input frequency range accommodates both European (50Hz) and some international (60Hz) grid standards.
- Integrated 12AH / 12VDC Battery Capacity: The onboard battery backup sustains connected devices during brief outages — critical for facilities where cameras must remain online during grid interruptions. 12AH provides meaningful runtime for low-to-moderate loads; calculate your actual camera and device draw to confirm runtime meets your site's AHJ or insurance requirements.
- PTC (Positive Temperature Coefficient) Overcurrent Protection: PTC protection on outputs self-resets after a fault clears, eliminating the nuisance of manually replacing blown fuses on a camera-by-camera basis in a multi-device installation. This reduces truck rolls for minor wiring faults.
- CE European Conformity: The T3AXK77F16SDV carries CE listing — required for equipment sold or deployed within the European Economic Area and often specified by international project bids. Confirm the specific CE directives covered with the project documentation before specifying on regulated installations.
- Large-Format Steel Enclosure: The 36.12" x 30.125" x 7.06" enclosure provides substantial internal space for cable management, battery installation, and future expansion of distribution wiring. At 84.2 lb., this is a two-person lift — plan your wall-mounting or rack-mounting approach before the unit arrives on site.
- Operating Temperature Range 0°C to 49°C: Rated for environments up to 49°C (121°F), which covers most conditioned equipment rooms and indoor utility spaces. The unit is not rated for outdoor or uncontrolled environments — install in a conditioned IDF, server room, or secured interior cabinet.
- 246 BTU/Hr Heat Dissipation: Plan ventilation in the enclosure space accordingly. In a sealed utility closet, 246 BTU/Hr of continuous heat output can raise ambient temperature meaningfully over time — ensure adequate airflow or active cooling if the room houses multiple power supplies or network equipment.
Integration & Compatibility
The T3AXK77F16SDV is voltage-output agnostic at the device level — any 24VDC surveillance camera, PTZ, or access control reader that draws within the 10A aggregate budget can be powered from this unit. It is commonly paired with IP cameras and analog PTZ cameras requiring regulated 24VAC/DC in international deployments. For multi-camera installations requiring PoE, this unit does not provide PoE — pair it with a PoE switch or midspan injector powered from the 24VDC bus if PoE devices are in scope.
Integrators sourcing power infrastructure for a full surveillance build should review the surveillance power supply category to compare channel count and amperage options across the Altronix line. For projects requiring structured cable distribution alongside power, the NVR and recording infrastructure section covers complementary head-end equipment.
The large enclosure accommodates field wiring from multiple homerun runs — suitable for centralized power architectures where individual camera feeds home-run back to an IDF rather than daisy-chaining power at each device location.
Frequently Asked Questions
Q: What input voltage does the T3AXK77F16SDV require?
A: The T3AXK77F16SDV requires 220VAC input at 50 or 60Hz. It draws 2.7A at input and is protected by a 6.5A/250V input fuse. It is not a dual-voltage unit — do not connect it to 120VAC circuits.
Q: What battery size does the T3AXK77F16SDV support?
A: The unit supports a 12AH/12VDC battery for backup power. Actual runtime depends on the total load draw of connected devices — calculate your combined camera and device current draw to estimate standby duration.
Q: Is the T3AXK77F16SDV CE listed?
A: Yes. The T3AXK77F16SDV carries CE European Conformity listing. Consult the product documentation for the specific CE directives covered before specifying on regulated projects.
Q: Does this unit provide PoE output for IP cameras?
A: No. The T3AXK77F16SDV outputs regulated 24VDC at up to 10A — it does not provide IEEE 802.3af/at PoE. For PoE-dependent cameras, you will need a separate PoE switch or injector.
Q: What is the operating temperature range of the T3AXK77F16SDV?
A: The unit is rated for operating temperatures from 0°C to 49°C (32°F to 120°F). It is designed for conditioned indoor environments such as equipment rooms and secured utility spaces — not for outdoor or uncontrolled ambient installations.
Q: How much does the T3AXK77F16SDV weigh, and are there mounting considerations?
A: The unit weighs 84.2 lb. (shipping weight 97.5 lb.). This is a two-person installation — ensure your wall or rack mount point is rated for the load, and plan your lift approach before the unit arrives on site.
The T3AXK77F16SDV is the unit I reach for when an international project spec calls for CE-listed centralized power and the site runs 220VAC — the combination of a 10A regulated 24VDC main bus, 1A auxiliary output, and 12AH battery backup in a single large-format enclosure eliminates the need to cobble together a separate UPS and distribution block. At 84.2 lb. fully assembled, this is not a one-person job, so factor crew size into your pre-installation planning.
Technical Highlights:
- 10A / 24VDC Main Output: Sufficient aggregate capacity for a meaningful camera count — but sum your device draws carefully. A mix of PTZ and fixed cameras can approach that ceiling faster than expected, especially with cold-weather heaters or wiper motors in the chain.
- PTC Overcurrent Protection: Self-resetting PTC fusing on outputs means a shorted homerun cable doesn't require a maintenance visit just to reset a fuse — the circuit recovers once the fault clears, which matters in remote or access-restricted equipment rooms.
- 246 BTU/Hr Heat Load: In a sealed equipment closet, that's non-trivial. I've seen thermal shutdowns in closets where multiple supplies were stacked without airflow planning — verify your room's BTU budget before commissioning, especially if other heat-generating equipment shares the space.
Deployment Considerations:
- The 6.5A/250V input fuse is correctly sized for the 2.7A input draw with headroom — but confirm the local circuit breaker and wiring gauge match before energizing. In international projects, local electrical codes vary significantly and the AHJ may require additional documentation beyond CE marking.
- The 0°C lower temperature limit means this unit is not suitable for unheated spaces in cold climates during winter — if your IDF drops below freezing, specify a unit with a rated low-temperature floor that matches site conditions.
This supply is well-positioned for centralized power architecture in European or Middle Eastern surveillance installations — hotel security rooms, airport concourse IDFs, or campus buildings where 220VAC is standard and CE compliance is a contract requirement, not optional.
