Selecting the supply voltage
Voltage is supplied to the Homematic IP Wired Access
Point via a separate power supply unit. Please use a pow-
er supply unit that is appropriate for application in house
installations. The basic requirements to the power supply
unit are:
• Output voltage: 24 V
DC
(±5%, or adjustable),
<50 mVss, SELV
• 10 A max., current-limited
• short circuit-proof
• at least 3750 V isolation voltage (input and out-
put)
• over-voltage category III
• EMV interference immunity according to
EN61000-6-2
• Power failure mains buffering: at least 80 ms
For example, you can use power supply units of the Step
Power Series by PHOENIX CONTACT (e.g. 24 VDC, 2.5 A:
STEP-PS/1AC/24DC/2.5).
