AES PSU-12V-US, 12V 1A Power Supply Slim for use with MON-11
The AES PSU-12V-US is a slim 12V 1A power supply listed for use with the AES MON-11 monitor. It is intended for compatible AES intercom monitor applications that require a 12V DC, 1 amp power source. This is a replacement power supply, not the MON-11 monitor itself.
The slim design makes it useful where space is limited around the outlet, wall monitor location, cabinet, or low-voltage equipment area. For service work, this part is commonly considered when the original MON-11 power adapter is missing, damaged, misplaced, or being replaced as part of a troubleshooting process.
What This Power Supply Does
The PSU-12V-US provides 12V DC power to a compatible AES device that is designed for this power supply. In the supplied listing, it is specifically identified for use with MON-11. Always confirm the device label, AES instructions, and connector requirements before connecting a replacement power supply.
- Provides 12V DC output for compatible AES equipment
- Rated at 1 amp output current
- Slim power supply design for tighter installation areas
- Listed for use with the AES MON-11 monitor
- Useful as a replacement for a missing or damaged compatible power adapter

Compatible With
The AES PSU-12V-US is intended for the AES MON-11 monitor and select AES intercom monitor applications where the current AES documentation, device label, or parts listing calls for a 12V 1A slim power supply. Compatibility should be confirmed before ordering because AES also uses 24V power supplies, PoE injectors, router supplies, and other power accessories across different product families.
- AES MON-11 monitor where PSU-12V-US is the specified replacement power supply
- Select AES intercom monitor applications requiring 12V DC at 1 amp
- Service replacements where the existing power adapter is marked PSU-12V-US
- Installations where a slim 12V 1A power supply is required by the AES device instructions
Important Compatibility Warning
Do not order or connect this power supply by appearance alone. Many power adapters look similar but use different voltages, current ratings, plug sizes, polarity, and output types. Using the wrong power supply can cause a device not to power up, behave unpredictably, or become damaged.
- Confirm the required part number is PSU-12V-US.
- Confirm the connected device is MON-11 or another AES device approved for this power supply.
- Confirm the device requires 12V DC, not 24V DC, 48V PoE, AC input, or another voltage.
- Confirm the 1 amp output rating is correct for the device.
- Confirm the connector size and polarity match the installed device.
- Do not use this power supply for gate motor power, relay switching, battery charging, or high-voltage circuits.

Technician Note
Before replacing a MON-11 power supply, check the original adapter label and the monitor power input label. Match voltage, output current, plug size, polarity, and regional plug type. A monitor that will not power up can also be caused by a bad outlet, damaged cable, loose connector, internal monitor issue, or incorrect adapter, so verify the simple items first.
Do not assume any 12V adapter is acceptable. The voltage may match while the current rating, polarity, plug size, regulation quality, or safety listing may not. For AES equipment, use the power supply specified by the model or confirmed by AES documentation.
Before Ordering, Confirm
- Confirm the exact part number is PSU-12V-US.
- Confirm the device being powered is AES MON-11 or another AES device that specifically calls for this supply.
- Confirm the required output is 12V DC.
- Confirm the required current rating is 1 amp.
- Confirm the plug size and polarity match the installed device.
- Confirm this is not being ordered for a 24V AES callbox power input.
- Confirm this is not being ordered in place of a PoE injector.
- Confirm this is not being ordered to replace the MON-11 monitor itself.
- Confirm the outlet and installation location are suitable for the power supply.
Installation and Service Notes
- Disconnect power before replacing or testing the adapter connection.
- Use only a compatible 12V DC power supply where the MON-11 or AES instructions call for it.
- Do not connect this adapter to 24V input devices.
- Do not use this adapter to power gate motors, locks, high-current accessories, or battery chargers.
- Do not cut or splice the power supply cable unless the current AES instructions specifically allow it.
- After replacement, verify the MON-11 powers up normally and communicates with the intended AES system where applicable.
- If the monitor still does not power up, check the outlet, connector, cable, monitor input, and system configuration before replacing additional parts.
Professional Advisory
Low-voltage power supply replacement should be handled carefully when the adapter powers an access control monitor tied to an automated gate or entry system. If there is uncertainty about voltage, polarity, wiring, PoE, or the correct AES power accessory, use a qualified gate access or low-voltage technician. Do not bypass fuses, safety circuits, monitored photo eyes, safety edges, emergency access, fire access equipment, or operator safety devices while troubleshooting power.
Product Questions & Answers
What is the AES PSU-12V-US used for?
The AES PSU-12V-US is a slim 12V 1A power supply listed for use with the AES MON-11 monitor and select AES intercom monitor applications that specifically call for this power supply.

No. PSU-12V-US is the power supply only. It does not include the MON-11 monitor, wall bracket, touchscreen, intercom, router, PoE injector, or access control equipment.
Is the PSU-12V-US a 12V power supply?
Yes. The PSU-12V-US is listed as a 12V DC, 1 amp power supply. Confirm the device label and current AES documentation before connecting it to any equipment.
Can this replace a 24V AES power supply?
No. A 12V 1A power supply should not be used in place of a 24V AES power supply. If the device calls for 24V DC, use the correct AES 24V power supply specified for that equipment.
Is this the same as an AES PoE injector?
No. The PSU-12V-US is a 12V DC power supply. A PoE injector is a separate network power accessory used only where the device is designed for PoE power.
What should be checked before replacing the power supply?
Before replacing the power supply, check the outlet, adapter label, output voltage, current rating, connector fit, polarity, cable condition, and MON-11 power input. A loose connector or wrong adapter can look like a failed monitor.
Can this power a gate operator or electric lock?
No. The PSU-12V-US is intended for compatible AES monitor/intercom power use. It should not be used to power gate operators, electric locks, magnetic locks, battery chargers, or other high-current access control loads.
