Grandstream 12V/1A PSU, 12 W Adapter for IP Phones and Intercoms

The Grandstream 12V/1A PSU turns wall power into 12 V DC at 1 A for Grandstream devices rated at that input. It suits GXP2100 phones, the GRP2614 and higher GRP models, and the GDS3710 door intercom, which ships with no adapter.

====

The Grandstream 12V/1A PSU powers Grandstream devices rated for 12 V DC at 1 A. It delivers up to 12 W and accepts any mains input from 100 to 240 V, so it is the part to order when a phone adapter goes missing or a device sits far from a PoE port.

Devices that use the 12V/1A PSU

Grandstream datasheets list a 12 V, 1 A input for:

• GXP2140, GXP2160 and GXP2170 phones.
• GRP2614, GRP2615, GRP2616, GRP2634, GRP2636, GRP2650 and GRP2670 phones.
• The GDS3710 door intercom, which comes with no adapter in the box.
• The HT704 and HT814 ATAs.

When an adapter beats PoE

All of these phones accept PoE, yet the plain switch in a small branch or hotel reception often has none. For a GDS3710 at a villa gate far from the network cabinet, one adapter is simpler than adding a PoE switch for a single door.

12V/1A, 12V/2A or a 5V adapter?

The 12V/2A unit gives 24 W and is meant for heavier devices such as the GAC2500 conference phone. The 5V/0.6A and 5V/1A adapters serve GRP2600 Essential phones and HT80x ATAs and will not run a 12 V device. Always match the voltage and current printed in your device's datasheet or on its rear label.

Frequently Asked Questions

Does the GDS3710 intercom include a power adapter?

No. Its datasheet lists 802.3af PoE or a 12 V/1 A adapter that is not included, and this PSU matches that rating.

Can I run a GXP2170 on this adapter instead of PoE?

Yes. The GXP2170 datasheet specifies a 12 V, 1 A adapter, which is exactly this unit.

Will it power a GAC2500 conference phone?

No. The GAC2500 needs 12 V at 2 A (24 W), so use the Grandstream 12V/2A PSU.
