Altronix MAXFIT77F8SDV 8-Output Distributed Power Supply
Overview
The Altronix MAXFIT77F8SDV is a distributed power supply built for commercial surveillance and access control installations running on 220VAC mains. It delivers up to 10A of total output across 8 individually addressable outputs, each configurable anywhere in the 2–24VDC range — making it a single hardware solution for mixed-voltage field devices on the same panel. At 24.8 lbs in a 19-gauge steel enclosure measuring 6.25 x 20.50 x 16.50 inches, this unit is sized for rack-room or back-of-house deployment where power distribution needs to be consolidated and protected.

Key Features
- 8 Independent Outputs: Each of the 8 outputs can be configured individually across the 2–24VDC range. That flexibility lets you power 12VDC PTZ cameras, 24VDC door locks, and low-voltage sensors from the same chassis — without separate supplies for each device class.
- 10A Total Output Capacity: With 10A across 8 outputs, you have roughly 1.25A average headroom per run — adequate for most camera or access control loads. Map your per-device draw before assignment; heavy PTZ or heater-equipped cameras will consume that headroom faster.
- 220VAC Input: Designed specifically for 220VAC mains input, this unit fits European, Latin American, and international site electrical standards where 120VAC Altronix variants would be the wrong pick. Confirm your facility's supply voltage before ordering — this is not dual-voltage.
- 19-Gauge Steel Enclosure: The formed steel cabinet resists physical tampering and provides a structured mounting point for terminal strips, boards, and cable management. At just over 24 lbs, it's a two-person lift for rack installation. Plan accordingly during site prep.
- 2–24VDC Output Range: The wide adjustable output band covers virtually every DC voltage requirement in a typical surveillance or access control system — from 5V auxiliary sensors up through 24V electric strikes and magnetlocks. No additional step-down converters needed for most mixed-load panels.
- Consolidated Field Power Distribution: Running 8 individually managed DC outputs from a single 220VAC source reduces the number of discrete wall-wart or transformer installations on site. Fewer power injection points means simpler troubleshooting and a cleaner installation audit trail. Pair with a compatible access control system for centralized credential and power management.
Integration & Compatibility
The MAXFIT77F8SDV is built to integrate with Altronix's broader MAXFIT and BC750 platform ecosystem. It pairs with surveillance cameras, door controllers, readers, and other low-voltage field devices operating anywhere in the 2–24VDC range. For multi-site or high-channel-count deployments, consider pairing with compatible network video recorders and structured cabling infrastructure to keep the full system power and data architecture under a single managed design. For power planning guidance, refer to a security camera selection guide to match per-camera wattage to available output budget before committing to a channel assignment.
Frequently Asked Questions
Q: What is the input voltage for the MAXFIT77F8SDV?
A: The MAXFIT77F8SDV is designed for 220VAC input. It is not a dual-voltage unit — verify your facility runs 220VAC mains before ordering.
Q: How many outputs does the MAXFIT77F8SDV provide?
A: It provides 8 individually configurable DC outputs, each adjustable across the 2–24VDC range.
Q: What is the total output current capacity?
A: Total output current is 10A across all 8 outputs. Plan device load per output to avoid exceeding the aggregate budget.
Q: What are the physical dimensions and weight of the MAXFIT77F8SDV?
A: The enclosure measures 6.25 x 20.50 x 16.50 inches and weighs 24.8 lbs. Plan for a two-person installation lift.
Q: What enclosure material is used in the MAXFIT77F8SDV?
A: The enclosure is fabricated from 19-gauge steel, providing structural rigidity and tamper resistance for commercial installations.
The MAXFIT77F8SDV is one of those units I spec when an international site or a 220VAC industrial facility needs consolidated DC distribution without running separate transformers for every device class. The 2–24VDC adjustable range on each of the 8 outputs is the key differentiator — you're not locked into 12V or 24V fixed rails.
Technical Highlights:
- 8 Adjustable Outputs (2–24VDC): Covers mixed-voltage loads — 12VDC cameras, 24VDC strikes, and low-voltage sensors — from a single chassis. Eliminates the per-device-class transformer stack that clutters most back-of-house panels.
- 10A Total Capacity on 220VAC: Sized for commercial-scale installations where 120VAC infrastructure isn't available. At 10A shared across 8 outputs, average per-output headroom is 1.25A — tight if you're running multiple heater-equipped outdoor cameras, so load planning is non-negotiable.
- 19-Gauge Steel at 24.8 lbs: The enclosure is genuinely robust — not a thin-wall cabinet. That weight is also a handling consideration: factor in two-person labor for rack or wall installation at 6.25 x 20.50 x 16.50 inches.
Deployment Considerations:
- Confirm 220VAC mains availability before procurement — this is a single-input-voltage unit, and there is no field switch to adapt it for 120VAC sites.
- Map per-output device wattage against the 10A aggregate before finalizing channel assignments. PTZ cameras with integrated heaters or high-wattage IR illuminators can consume 2–3A per device, which compresses available headroom quickly across 8 outputs.
Best fit for international commercial facilities, manufacturing sites, or warehouse security installations running 220VAC infrastructure where mixed-voltage DC distribution needs to be consolidated into a single, auditable power panel.
