Altronix MAXIMAL33FV 16-Output 220VAC Surveillance Power Supply
Overview
The Altronix MAXIMAL33FV is a 16-output, 220VAC-input power distribution unit engineered for large-scale surveillance power supply deployments where the local mains runs at 220VAC 50/60Hz — common across international sites, industrial facilities, and campus environments that don't run North American 120VAC infrastructure. It delivers selectable 12VDC or 24VDC output across 16 individually fused channels, with a main output current of 4.2A and a per-channel rating of 2.5A, making it a practical fit for powering banks of analog or low-voltage IP cameras from a single, cabinet-mounted source.

Key Features
- 220VAC 50/60Hz Input: Designed from the ground up for international mains voltage — no step-down transformer required on 220VAC infrastructure. If your site runs 220VAC (common in Europe, Latin America, and industrial US facilities with dedicated circuits), this eliminates the adapter stage that introduces failure points and eats rack space.
- Selectable 12VDC or 24VDC Output: A single unit covers both 12VDC analog cameras and 24VDC PTZ or access control devices. Switching output voltage at the board level means you can standardize on one SKU across mixed-device deployments rather than stocking two separate supplies.
- 16 Individual Output Channels at 2.5A Each: Sixteen discrete outputs let you assign one channel per camera and fault-isolate problems without taking down the entire power zone. At 2.5A per channel, each output comfortably covers standard analog or low-voltage cameras with margin to spare for cable runs with minor voltage drop.
- 4.2A Main Output Current: The main bus delivers 4.2A continuously, with a maximum supply current ceiling of 5.3A at either 12VDC or 24VDC. That headroom matters during camera startup surges — especially on cold mornings when motors and heaters in PTZ housings draw peak current simultaneously.
- 3.5A Auxiliary Output: The auxiliary output (5.6A max supply current) provides a separate power rail for access control panels, alarm inputs, or ancillary devices that shouldn't share a bus with cameras. Keeping control hardware on a dedicated rail reduces noise coupling and simplifies fault tracing.
- CE Agency Listing: CE marking confirms the unit meets European safety and electromagnetic compatibility directives — a hard requirement for installations in CE-jurisdictions and a baseline quality signal for commercial deployments anywhere.
- Thermal Efficiency — BTU/Hr Ratings: At 12VDC the unit dissipates 65 BTU/Hr; at 24VDC, 138 BTU/Hr; running both rails simultaneously, 101 BTU/Hr. These are real numbers to plug into your enclosure cooling calculations — a 19" rack cabinet in a sealed IDF closet will see meaningful heat accumulation from this unit at full 24VDC load, so plan ventilation accordingly.
- Operating Temperature 0°C to 49°C: Rated for standard conditioned equipment rooms and light industrial environments. This is not an outdoor or unheated space unit — if your IDF closet runs hot in summer, verify ambient stays under 49°C (120°F) at the chassis level.
- Large Cabinet Form Factor — 26" × 19" × 6.25", 43.5 lbs: The physical footprint is substantial. At 26 inches tall in a 19-inch rack profile, plan for roughly 15U of vertical space (verify rack unit count against your specific cabinet). The 43.5 lb installed weight means this belongs in a floor-standing rack with proper rail support — not a wall-mount bracket or light-duty enclosure.
Integration and Compatibility
The MAXIMAL33FV is compatible with the broader Altronix MAXIMAL series ecosystem, including the EFLOW6NB power modules and ACM8 access control modules called out in the full product configuration. The 16-output architecture pairs naturally with analog CCTV cameras and low-voltage IP devices drawing regulated DC power from a centralized source. For sites requiring coordinated access control power alongside camera infrastructure, the auxiliary rail integrates with Altronix ACM-series multiplexers without requiring a separate supply. Consult your power planning guide to calculate cable run losses and confirm per-channel voltage at the device — long runs on 12VDC see meaningful drop that may push you toward 24VDC output and step-down at the device. For complementary distribution hardware, consider pairing with a managed PoE switch if any cameras in the deployment have migrated to IP/PoE.
Frequently Asked Questions
Q: What input voltage does the MAXIMAL33FV require?
A: The MAXIMAL33FV requires 220VAC at 50/60Hz. It is not designed for standard North American 120VAC mains without a step-up transformer. Verify your facility's mains voltage before ordering.
Q: Can the MAXIMAL33FV output both 12VDC and 24VDC at the same time?
A: The unit supports selectable 12VDC or 24VDC output. The BTU/Hr rating for simultaneous dual-voltage operation (101 BTU/Hr) is listed in the specs, indicating dual-rail capability — however, verify the specific configuration with your Altronix documentation, as channel allocation between rails depends on the installed module configuration.
Q: How many cameras can the MAXIMAL33FV power?
A: The unit provides 16 individually fused output channels at 2.5A each. How many cameras that supports depends on each camera's current draw — a typical analog camera drawing 500mA would allow up to 16 devices, one per channel, within per-channel limits.
Q: Is the MAXIMAL33FV suitable for outdoor enclosure installation?
A: The operating temperature range is 0°C to 49°C, which covers conditioned equipment rooms and light industrial interiors. It is not rated for unheated or unventilated outdoor enclosures where ambient temperatures may fall below 0°C or exceed 49°C.
Q: What is the weight of the MAXIMAL33FV and what rack space does it require?
A: The installed unit weighs 43.5 lbs (19.73 kg) with a shipping weight of 47.5 lbs. Dimensions are 26" × 19" × 6.25". This requires a robust floor-standing rack with proper rail support — verify rack unit height against your cabinet specifications before installation.
Q: What agency listings does the MAXIMAL33FV carry?
A: The MAXIMAL33FV carries CE certification, confirming compliance with European safety and electromagnetic compatibility requirements.
The MAXIMAL33FV is one of the few centralized surveillance power solutions in the Altronix lineup purpose-built for 220VAC input — and that single fact either makes it the right call or eliminates it entirely. If your project is a North American site on standard 120VAC, stop here and look at a different MAXIMAL variant. But if you're commissioning a hotel, manufacturing plant, or international campus where the mains infrastructure runs 220VAC 50/60Hz, this unit earns its place: 16 individually fused channels, selectable 12VDC or 24VDC, with a main bus rated to 5.3A max supply current.
Technical Highlights:
- Dual-Voltage Output (12/24VDC): Field-selectable output means one unit can serve both 12VDC analog cameras and 24VDC PTZ or access control devices — important on retrofit projects where the device mix is rarely uniform.
- Auxiliary Rail at 3.5A / 5.6A Max: The dedicated auxiliary output physically separates access control panel power from camera power. That separation matters when you're troubleshooting a door strike not releasing — you're not hunting through camera channels to find the interference source.
- BTU/Hr at Load: At full 24VDC load the unit dissipates 138 BTU/Hr. In a sealed rack cabinet at an ambient 35°C, that's enough thermal output to push cabinet temps toward the 49°C operating ceiling. Budget active ventilation or a perforated door — passive convection alone won't be enough in warm server rooms.
Deployment Considerations:
- At 43.5 lbs installed and 26 inches tall, this belongs in a floor-standing rack on proper shelf rails — confirm your rack's weight rating before mounting, especially if other heavy equipment shares the same frame.
- Storage temperature goes down to -20°C, but the operating floor is 0°C — if this unit is going into an unheated staging area or shipping container deployment, it must be powered and self-heating before cameras come online, or you risk condensation and out-of-spec operation.
This unit is a strong fit for international hospitality or commercial campus projects — specifically a hotel or multi-building complex on 220VAC infrastructure where the integrator needs to centralize camera power in a single IDF closet per floor, with enough channel count to cover a full wing of cameras without cascading multiple smaller supplies.
