Grandstream 12V/2A PSU, 24 W Adapter for Conference Phones

The Grandstream 12V/2A PSU is the high-current option in Grandstream's small adapter range: 12 V at 2 A, or 24 W. It is the spare to keep for a GAC2500 conference phone.

====

The Grandstream 12V/2A PSU supplies 12 V at 2 A, a full 24 W, which is what the GAC2500 conference phone lists in its datasheet. The adapter takes 100 to 240 V mains input.

Who needs the 12V/2A PSU

The GAC2500 audio conference phone states 12 VDC, 2 A and 24 W in its official datasheet, the same rating as this adapter.

For meeting rooms without PoE+

In a meeting room with no PoE+ switch, it runs a GAC2500 from the nearest socket.

12V/2A or 12V/1A?

Same voltage, different current: 2 A gives 24 W against 12 W from the 12V/1A unit. The 1 A model is sized for GXP2100 phones, the GRP2614 and the GDS3710; it falls short for a GAC2500, whose datasheet calls for 2 A. The 5 V adapters do not fit this device.

Frequently Asked Questions

Does a GAC2500 need an adapter if I have a PoE+ switch?

No, PoE+ is enough. The adapter is for rooms without PoE+ or as a replacement for the original unit.

How is it different from the 12V/1A adapter?

Same voltage, different current: 2 A gives 24 W against 12 W from the 12V/1A unit. The 1 A unit falls short for a GAC2500, whose datasheet calls for 2 A.

Specifications
