Altronix MAXIMAL35EV 220VAC Dual-Voltage Surveillance Power Supply
Overview
The Altronix MAXIMAL35EV is a high-capacity, 220VAC-input power distribution unit built for commercial surveillance installations that demand reliable, battery-backed power across multiple devices. Designed for international deployments and 220V-only facilities — manufacturing plants, ports, international campuses, and industrial warehouses — this unit delivers regulated 12VDC and/or 24VDC output with enough current capacity to support distributed camera runs across a full building wing. At 484VA system input and a 43.5-lb steel enclosure measuring 26" x 19" x 6.25", this is a rack-room or closet installation built for serious, permanent deployments, not a lightweight field unit.
The MAXIMAL35EV operates on 220VAC at 50/60Hz — which means it works on both 50Hz (European, Asian, South American grid standard) and 60Hz (North American industrial 220V feeds), making it a versatile choice when you're designing a system that spans multiple countries or operates in a facility with dedicated industrial power rather than standard 120V branch circuits. Input current draw is rated at 2.2A at 220VAC, so plan your circuit accordingly: this unit pulls the equivalent of a 484VA load, and your upstream breaker should be sized with headroom above that.
Key Features
- Dual-Voltage Output (12VDC and/or 24VDC): Two output configurations let you match power to device requirements without a secondary converter. Option A delivers 12VDC at either 6A or 10A — useful for high-density 12V camera runs. Option B splits the load: 24VDC at 6A and 12VDC at 10A simultaneously. If your install mixes 24VDC PTZ receivers or access control hardware alongside 12VDC cameras, Option B eliminates the need for a separate 24V supply.
- 484VA System Input Capacity: At 484VA, this unit has headroom for substantial device loads. That's not a ceiling you'll approach with a modest 8-camera install — this is the right unit when you're powering 20+ devices, long wire runs with voltage drop margins, or a combination of cameras, PTZs, and field devices from a single distribution point.
- Four 12AH Battery Support: The MAXIMAL35EV supports up to four 12AH batteries (not included), which means genuine runtime during grid outages — not just a UPS trickle. Four 12AH batteries at 0.7A per power supply board charge current gives you the backup depth that critical entrances and perimeter cameras require. Size your battery runtime to scene priority and expected outage duration.
- 0.7A Per P/S Board Charge Current: Charge current is managed at 0.7A per power supply board, which protects battery health during long float cycles. Slow, controlled charging extends battery service life in always-on surveillance installations where batteries may sit at float for months between outages.
- 3.5A/250V Fuse Rating: Individual fuse protection at 3.5A/250V limits fault propagation — a short on one circuit branch doesn't cascade to the rest of the distribution panel. For multi-zone deployments, this is the difference between one camera going dark and an entire sector losing power.
- Operating Temperature 0°C to 49°C (32°F to 120°F): The rated ambient range covers most enclosed equipment rooms and conditioned mechanical spaces. If your install location runs warmer than 49°C — unconditioned rooftop closets in hot climates, for example — plan for supplemental ventilation or a different housing approach. This is an indoor enclosure unit.
- Heat Dissipation: 98.27 BTU/Hr (12VDC config) / 130.00 BTU/Hr (12/24VDC config): These BTU figures matter for your equipment room thermal budget. In a tight rack closet with multiple units, 130 BTU/Hr per chassis adds up quickly. Factor these numbers into your HVAC or ventilation planning before you commission the room.
- Steel Enclosure, 26" x 19" x 6.25": The enclosure dimensions are critical for wall-mount or rack-adjacent planning. At 26" tall and 19" wide, this is not a standard 19" rack unit — plan for dedicated wall-mount or floor-mount installation with adequate clearance for wiring and battery access.
Integration & Compatibility
The MAXIMAL35EV fits naturally into Altronix power distribution systems and is designed to pair with surveillance cameras, PTZ receivers, access control panels, and other 12VDC/24VDC field devices common in IP camera and analog surveillance infrastructure. The dual-voltage output in Option B makes it compatible with mixed-voltage architectures where 24VDC PTZ drives or intercom hardware co-exist with standard 12VDC cameras on the same distribution panel. When planning cable runs from this power supply, account for voltage drop on long 18AWG or 22AWG wire runs — at 10A aggregate output, resistance losses on multi-hundred-foot runs can pull voltage below camera operating minimums. Use a voltage drop calculator and upsize wire gauge or segment runs accordingly. For installations requiring UL-listed power distribution to meet local code or insurance requirements, verify the specific listing marks applicable to your jurisdiction before specifying this unit — confirm with your authority having jurisdiction (AHJ). Review Altronix's access control power line for companion units if your project also requires credential reader or lock power distribution.
Frequently Asked Questions

A: The MAXIMAL35EV requires 220VAC input and supports both 50Hz and 60Hz grid frequencies, making it suitable for international deployments and North American industrial 220V circuits alike.
Q: What are the two output voltage configuration options for the MAXIMAL35EV?
A: Option A delivers 12VDC at 6A or 10A. Option B delivers 24VDC at 6A and 12VDC at 10A simultaneously — useful for installations mixing 24VDC and 12VDC devices on the same distribution panel.
Q: How many batteries can the MAXIMAL35EV support, and what size?
A: The MAXIMAL35EV supports up to four 12AH batteries (not included), providing substantial backup runtime for critical surveillance circuits during grid outages.
Q: What is the enclosure size of the MAXIMAL35EV, and does it fit in a standard 19-inch rack?
A: The enclosure measures 26" x 19" x 6.25". At 26" tall and 19" wide, it is not a standard 19-inch rack unit. Plan for dedicated wall-mount or floor-mount installation with clearance for cabling and battery access.
Q: What is the maximum operating temperature for the MAXIMAL35EV?
A: The rated ambient operating range is 0°C to 49°C (32°F to 120°F). Installation locations that exceed 49°C — such as unconditioned rooftop closets in hot climates — require supplemental ventilation or an alternative housing solution.
Q: What heat load does the MAXIMAL35EV add to an equipment room?
A: In the 12VDC-only configuration, the unit dissipates 98.27 BTU/Hr. In the 12VDC/24VDC dual-voltage configuration, heat output rises to 130.00 BTU/Hr. Factor these figures into your equipment room HVAC and ventilation planning, especially in multi-unit installations.
When I'm specifying centralized power for large-format surveillance systems running on 220VAC infrastructure, the MAXIMAL35EV is the Altronix unit I reach for — specifically because of its 484VA input capacity and the Option B dual-voltage output that lets a single chassis serve both 12VDC cameras and 24VDC PTZ or intercom hardware simultaneously. That combination cuts head-end closet complexity on international or industrial-grid projects where you'd otherwise need two separate supply units.
Technical Highlights:
- 484VA System Input: This isn't a light-duty supply — at 484VA, you have real headroom for high-device-count camera runs, long-distance voltage-dropped circuits, or mixed-device loads without riding the supply's ceiling.
- Four 12AH Battery Support at 0.7A Charge: Four 12AH batteries represent serious backup depth for perimeter and entry-point cameras. The controlled 0.7A-per-board charge rate matters for long-term battery health in always-on installations where you may not cycle batteries for months.
- Dual-Voltage Output Option B (24VDC @ 6A + 12VDC @ 10A): Running PTZ receivers, intercom hardware, or 24V access control readers alongside standard 12V IP cameras from a single distribution panel is a real installation simplifier — fewer chassis, less wiring complexity, smaller conduit runs.
Deployment Considerations:
- At 43.5 lbs and 26" x 19" x 6.25", pre-plan your wall-mount or floor-mount anchoring well before the unit ships — this is not a two-person lift in tight spaces, and the enclosure won't land in a standard rack bay.
- The 49°C ambient ceiling is the hard constraint to watch in unconditioned spaces. Equipment closets in warm climates, rooftop penthouses, and un-cooled server rooms routinely exceed this — verify room temperature at peak load before you specify this unit for those environments.
The MAXIMAL35EV is the right specification for permanent, conditioned-room installations at international facilities, manufacturing campuses, or any 220V-grid site where you need battery-backed dual-voltage distribution for 20+ cameras and mixed-device infrastructure — and where you're willing to plan the thermal and structural mounting details the unit's size demands.
