PRODUCT DESCRIPTION
The POE.4AT-AC1 is a DIN rail mountable Power over
Ethernet (PoE) injector which comes with an integrated
PULS Power Supply of the highly reliable DIMENSION
product family. It can inject full 30W to each of 4
individual PoE channels (according to IEEE 802.3at) via
RJ45 Ethernet ports, so no power sharing is limiting theuse of single channels. The device can supply powered
devices PD of type1 and type2 (PoE+).
If more channels are needed you might also beinterested in the 8 channels version, POE.8AT-AC1 withthe same housing size.

the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is
calculated according to the capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only
guarantees a maximum life of up to 15 years (131 400h). Any number exceeding this value is a calculated theoretical
lifetime which can be used to compare devices.

16. PROTECTION FEATURES
Output protection

Electronically protected against overload, no-load and short-circuits. In case of aprotection event, audible noise may occur.

Output over-voltage protection

Typ. 58.5Vdc
Max. 60Vdc

In case of an internal power supply defect, a redundantcircuit limits the maximum output voltage. The output
shuts down and automatically attempts to restart.

Degree of protection

IP 20

EN/IEC 60529

Penetration protection> 4mm

E.g. screws, small parts

Over-temperature protection

Yes

Output shut-down with automatic restart.
The temperature sensor is installed on criticalcomponents inside the unit and turns the unit off insafety critical situations (e.g. derating requirements notobserved, high ambient temperature, ventilation
obstructed, or the mounting orientation derating is notfollowed). There is no correlation between theoperating temperature and turn-off temperature since
this is dependent on input voltage, load andinstallation methods.

18. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by the
manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the voltage
with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings to the value in the table below.

23. APPLICATION NOTES
23.1. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 20A. An external protection is only required if the supplying
branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local
regulations might apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or C-Characteristic breaker should be used.

23.2. OPERATION ON TWO PHASESThe power supply can also be used on two-phases of a three-phase-system. Such a phase-to-phase connection isPower Supply
allowed as long as the supplying voltage is below 240V+10%.
