1 Year WarrantyIncludedThe Generic Cisco ATA Series Power Supply Adapter (PWR-5V-2.4A) is a replacement AC/DC power solution for compatible Cisco analog telephone adapter deployments. It assists in restoring reliable power to compatible Cisco ATA devices, which are used to link IP-based voice networks to analog phones, fax machines and other legacy endpoints. Cisco ATA 191 and ATA 192 units support 100–240V AC, 50/60 Hz input, although their designated adaptor requires 5V DC input at up to 2.4A. Verify the precise ATA model and original adapter label prior to purchase or installation because different Cisco ATA generations may require different connectors, polarity and power. This is particularly crucial when switching out adapters for older ATA-186 or ATA-188 units with those for ATA 191/192 platforms.

Key Features
Replacement power adapter format for compatible Cisco ATA Series analog telephone adapters.
Supports stable AC-to-DC power delivery for Cisco VoIP adapter installations.
Designed for use in analog telephone, fax and IP telephony conversion environments.
Compatible replacement applications may include Cisco ATA 191 and ATA 192 units when voltage, current, connector size, and polarity match the device requirement.
ATA 191 and ATA 192 platforms use a 5V DC input requirement with up to 2.4A maximum input current.
Universal input requirement for ATA 191/192-compatible adapters: 100–240V AC, 50/60 Hz.
Compact external power design keeps heat and power conversion outside the ATA enclosure.
Ideal as a lost, damaged, or spare Cisco ATA power supply replacement.
Suitable for home office, small business, managed VoIP, branch-office and telecom-maintenance applications.
Benefits
- Helps bring a compatible Cisco analog telephone adapter back into service without replacing the complete VoIP device.
- Supports uninterrupted connectivity for analog telephones and fax equipment operating through an ATA.
- Gives telecom administrators and field technicians a practical spare-power option for supported Cisco ATA installations.
- Universal AC input compatibility supports use across common 100–240V electrical environments when paired with the correct regional AC cord or plug configuration.
- Enables a cost-effective maintenance approach for legacy analog endpoint and SIP telephony deployments.
- Reduces installation risk when the replacement adapter is matched to the ATA’s exact DC voltage, current capacity, barrel connector dimensions and polarity requirements.

Frequently Asked Questions
Generic Cisco ATA Series Power Supply Adapter (PWR-5V-2.4A) | Recertified
What output voltage should this Cisco ATA adapter provide?
This generic replacement is intended for compatible Cisco ATA devices requiring 5V DC. Cisco’s ATA 191/192 user guide specifically identifies a 5V DC power connector.
What current rating is commonly used by compatible Cisco ATA models?
Cisco specifies a 5V DC input at 2.0A maximum for the SPA112 and SPA122. A replacement supply must provide the correct voltage and adequate current capability for the exact ATA model.
Is this a genuine Cisco OEM power adapter?
No. This listing is for a generic replacement adapter intended to meet the power requirements of compatible Cisco ATA equipment.
Can it be used with a Cisco ATA 191?
Potentially, provided the generic adapter has the correct connector, polarity, voltage, and current capability. Cisco confirms that the ATA 191 uses a 5V DC power connection and lists ATA191-PWR as its spare power adapter.
Can it power a Cisco ATA 192?
Yes, when all electrical and connector specifications match. Cisco documents the ATA 192 with the same 5V DC power connector used by the ATA 191.
Is it compatible with the Cisco SPA112?
It can be compatible when the connector and polarity match. Cisco specifies the SPA112 power input as 5V DC at 2.0A maximum.
Can it be used with the Cisco SPA122?
The SPA122 also has a published 5V DC, 2.0A maximum power requirement, so a properly matched replacement adapter can be suitable. Connector and polarity must still be confirmed.
Does a higher current-capability adapter damage the ATA?
Not simply because its maximum current rating is higher. A device draws the current it requires, provided the adapter supplies the correct voltage, polarity and connector. However, only use a replacement that meets all device specifications.
Can I use a power supply with a different voltage?
No. Do not substitute a different output voltage unless Cisco documentation for the exact ATA model explicitly permits it. Incorrect voltage can prevent operation or permanently damage the device.
Why must polarity be checked?
Barrel-style DC connectors can use different center-positive or center-negative configurations. Matching voltage alone is not enough; incorrect polarity can damage electronic equipment.
How can I confirm compatibility before ordering?
Check the label on the bottom or rear of the Cisco ATA and compare it with the original adapter. Verify DC voltage, required current, plug dimensions, polarity and input connector type.
Does the Cisco ATA 191 use Power over Ethernet instead of an adapter?
Cisco’s user guide identifies a dedicated DC 5V POWER connector and instructs users to connect the supplied power adapter to it.
Will replacing the power adapter erase ATA settings?
Normally, no. Disconnecting and restoring external power does not itself factory-reset an ATA. Configuration remains stored unless a separate reset procedure is intentionally performed.
Can this adapter help troubleshoot a Cisco ATA that will not power on?
Yes. Testing with a verified compatible supply can help determine whether the original external power adapter has failed. Further troubleshooting may be needed if the ATA remains unresponsive.
Can a Cisco ATA be connected to a UPS?
Yes. Cisco’s ATA 191/192 user documentation even lists an uninterruptible power supply as equipment that can be used to provide backup power.
Why would a business keep spare ATA power adapters?
External power supplies are replaceable components that can be lost or damaged. Keeping compatible spares can reduce downtime for phones, fax machines, paging adapters, or other analog equipment relying on the ATA.
What devices can Cisco ATAs support?
Depending on the ATA model and configuration, Cisco documents support for analog phones, fax machines, analog telephony devices and overhead paging systems.
Does this power adapter affect VoIP call quality?
A properly functioning, electrically compatible adapter should simply supply power to the ATA. Voice quality is primarily affected by the ATA, network, codec, service configuration and connected equipment rather than by the adapter itself.
Is an Ethernet cable included with this generic power supply?
No. This listing is for the power adapter only unless the seller explicitly states otherwise. Ethernet and telephone cables should be purchased separately when needed.
What is the most important consideration when buying a generic ATA adapter?
Do not rely on the Cisco brand name or physical appearance alone. Confirm the exact ATA model, DC voltage, amperage requirement, connector dimensions and polarity before connection. This is especially important because Cisco has produced several ATA families with different hardware generations.
