Description
The Ekinex® 640 mA KNX bus power supply supplies and monitors the 30 Vdc voltage
required by the KNX bus for operation. An integrated choke provides for decoupling
power supply and bus line. On a bus line powered by a 640 mA power supply unit may
be connected a maximum of 64 bus devices. Output is protected from overload and
short-circuit. The EK-AG1-TP version is provided with an additional 30 Vdc output
can be used as auxiliary power supply for other devices requiring SELV voltage
(Safety Extra Low Voltage). The total current provided by the two outputs (KNX bus
line and auxiliary power supply) cannot exceed 640 mA. The device supports short
network voltage interruptions (max. 200 ms).
Main features
• Plastic casing
• Connection to bus line with KNX terminal block
• Connection of auxiliary output with dedicated terminal block (only EK-AG1-TP)
• Connection of 230 Vac power supply with screw terminals

Description
The Ekinex® EK-AM1-TP power supply produces and monitors the 30 Vdc voltage
required for operation of the KNX bus system. A coil integrated in the device
decouples the power supply from the bus line. The output has overload and short-
circuit protection. It has an additional 30 Vdc output that can be used for auxiliary
supply of other SELV devices. The total current provided by the two outputs (KNX bus
line and auxiliary power supply) cannot exceed 1280 mA. The device is capable of
supporting short mains voltage interruptions (max. 200 ms).
Main features
• Plastic housing
• Connection to bus line via KNX terminal
• Auxiliary power connection via dedicated screw terminals
• Power supply connection via screw terminals
• Degree of protection IP 20 (device installed)
• Climatic classification 3K5 and mechanical classification 3M2 (according to EN 50491-2)
• Pollution degree 2 (according to IEC 60664-1)
• Safety class I
• Mounting on 35 mm profile rail (according to EN 60715)
• Device with 4 modular units (1 UM = 18 mm)
• Weight 320 g
Technical data
• Supply voltage 230 Vac, 50/60 Hz
• Power consumption 39 W
• Losses < 3 W
• Voltage on bus line: 30 Vdc +1/-2 Vdc SELV
• Voltage on auxiliary output: 30 Vdc
• Nominal current: 1280 mA
