Grandstream 5V/1A PSU, Power Adapter for HT80x ATAs and DP750

The Grandstream 5V/1A PSU delivers 5 V at 1 A (5 W), the input Grandstream lists for its small ATAs and DECT base. It fits the HT801 and HT802 analog adapters and the DP750 base station.

====

The Grandstream 5V/1A PSU outputs 5 V at 1 A (5 W). That is the input Grandstream lists for the HT801 and HT802 analog telephone adapters and the DP750 DECT base station, and the unit accepts 100 to 240 V mains.

Where the 5V/1A PSU fits

• HT801 ATA with one phone port.
• HT802 ATA with two phone ports.
• DP750 DECT base, which can also run on PoE.

Why keep a spare for an HT802

The HT801 and HT802 have no PoE, so the adapter is their only power source. If it fails, the fax machine or analog phone behind the ATA goes dead, whether at a clinic front desk or a hotel back office. A DP750 mounted on a warehouse wall away from any PoE switch can run from this unit too.

5V/1A or 5V/0.6A?

They differ in current and purpose. The 5V/0.6A model is the 600 mA adapter for GRP2600 and GXP1600 phones; the 5V/1A model serves HT80x ATAs and the DP750.

Frequently Asked Questions

Does the HT802 support PoE?

No. Grandstream lists only a 5 V, 1 A adapter for the HT802, which is why a spare is worth having.

Will it power a DP750 base?

Yes. The DP750 datasheet lists a 5 VDC, 1 A adapter, and the base also accepts 802.3af PoE.

Can I use it on a GRP2602?

The GRP2602 is rated 5 V at 600 mA; the adapter made for it is the Grandstream 5V/0.6A PSU.
