AES PSU-2AMP-24V-US, 24V 2A DC Power Supply Transformer w/US AC cable & plug (Suitable for all AES callboxes)
The AES PSU-2AMP-24V-US is a 24VDC 2A power supply transformer for compatible AES callboxes, intercoms, and access control equipment that require a 24V DC power source. The supplied product title identifies this item as a 24V 2A DC power supply transformer with US AC cable and plug.
This power supply is used when the installed AES device requires a properly rated 24VDC supply and the original power supply is missing, damaged, failed, or no longer providing stable output. It may be used for compatible AES callbox applications where the voltage, current rating, lead style, connector type, polarity, and power requirements match the installed equipment.
Power supply selection should never be based on voltage alone. Confirm the part number, output voltage, output amperage, connector or lead arrangement, polarity, enclosure requirements, and AES model documentation before installing this supply. Some supplier listings for PSU-2AMP-24V-US describe different lead/adaptor details, so the actual stock package should be confirmed before publishing exact included-cable language.
What This Power Supply Does
The PSU-2AMP-24V-US provides 24V DC power for compatible AES equipment. A correct and stable power supply is important for normal callbox operation, audio/video performance, relay operation, keypad function, network communication, app connectivity, and general system reliability.

- North American installations where the US AC cable/plug package is confirmed
Important Compatibility Warning
Do not order or install this power supply by appearance only. AES equipment may use different voltage ratings, PoE requirements, DC barrel connectors, bare leads, polarity arrangements, power supplies, routers, monitors, and accessory power options. Match the exact power requirement before connecting the unit.
- Confirm the exact part number is PSU-2AMP-24V-US.
- Confirm the installed AES unit requires 24VDC output.
- Confirm the installed AES unit can be powered by a 2 amp supply.
- Confirm the connector, lead style, polarity, and cable length match the installation.
- Confirm whether your stock package includes the US AC cable and plug.
- Confirm whether the system requires 24VDC power, PoE, a router power supply, monitor power supply, or a different accessory supply.
- Confirm the power outlet, enclosure, surge protection, and cable routing are suitable for the installation.
- Do not substitute this unit for a gate operator transformer, battery charger, PoE injector, or non-AES power supply unless the documentation confirms it.
Similar AES Power and Accessory Parts That Are Not Automatically Interchangeable
- AES IL-POE-PSU-US: In-line PoE injector with USA AC lead. This is not the same as a 24VDC 2A power supply.
- AES PSU-12V-US: 12V 1A slim power supply for compatible MON-11 applications. This is a different voltage and should not be used in place of a 24VDC supply.
- AES RB-4G-US: Router kit in an IP65 enclosure. This is network hardware, not a general callbox power supply.
- AES OPYN-MON-US and OPYN-MON-10-US: Indoor touchscreen monitors. These may have their own power requirements and are not power supplies.
- AES OPYN and OPYN Pro callboxes: Complete intercom systems. The power supply does not replace the callbox electronics, keypad, camera, or relay board.
- Generic 24V power adapters: Generic adapters may not match the lead style, polarity, output quality, listing requirements, or installation needs of the AES equipment.
Not Intended For
- Replacing a complete AES intercom or callbox
- Replacing a PoE injector when PoE is required
- Replacing a 12V power supply
- Replacing a router power supply unless the router documentation confirms 24VDC 2A compatibility
- Replacing a monitor power supply unless the monitor documentation confirms this exact supply
- Charging batteries unless the AES documentation specifically calls for this supply
- Powering a gate operator motor or high-voltage operator circuit
- Use where the required voltage, polarity, connector, or amperage is different

Technician Note
A weak, failing, or incorrect power supply can create problems that look like a bad callbox: intermittent resets, poor audio, relay issues, screen issues, keypad lockups, failed network communication, or no power. Before replacing electronics, confirm the AES unit is receiving the correct 24VDC power under load.
Do not assume every 24V adapter is interchangeable. The voltage must match, the current rating must be adequate, the polarity must be correct, and the connector or lead style must match the installed unit. If the site uses PoE or a different AES power accessory, use the power method specified for that model.
Before Ordering, Confirm
- Confirm the exact part number is PSU-2AMP-24V-US.
- Confirm the installed AES equipment requires 24VDC power.
- Confirm a 2 amp supply is correct for the installed unit.
- Confirm the connector, bare-wire leads, polarity, and cable length match the installation.
- Confirm your stock package includes the US AC cable and plug if that is required.
- Confirm the installation does not require PoE instead of a DC power supply.
- Confirm the outlet, enclosure, surge protection, conduit, and cable routing are suitable.
- Confirm there is no water intrusion, damaged wiring, short circuit, or failed board that could damage the replacement supply.
Installation and Service Notes
- Disconnect power before servicing or replacing the power supply.
- Verify voltage and polarity before connecting the supply to the AES unit.
- Do not connect 24VDC to a device that requires 12VDC, PoE only, or another power method.
- Do not overload the power supply by powering extra accessories unless the total load is confirmed.
- Route low-voltage wiring so it is protected from pinch points, sharp edges, water entry, and gate movement.
- Use surge protection and proper grounding/bonding methods where required by site conditions and local code.
- Keep power wiring separated from high-voltage wiring where practical.
- After installation, test the AES unit under normal call, keypad, relay, network, and standby conditions.
Professional Advisory
Power supply replacement should be handled by a qualified gate access, low-voltage, or access control technician when the installation condition is unclear. Do not modify high-voltage wiring, bypass safety circuits, bypass emergency access equipment, bypass fire access equipment, or connect the power supply to unapproved loads. For unsafe wiring, water damage, repeated blown supplies, tripped breakers, or unknown power faults, stop and have the system inspected before reconnecting power.
