Power Supply CP-ASI/8.0

Primary switch mode power supply for AS-interface

The CP-ASI power supply range is speciﬁcally

designed with integrated data decoupling for the

supply of AS-Interface systems.

Up to 62 slaves (binary I/O devices) can be

supplied with a single two-conductor cable.

The conﬁgurable IR addressing mode allows the

easy assign of new ID addresses by means of an

external infrared programming unit.

Application

The primary switch mode power supply is specifically designed with integrated data decoupling for the supply of ASinterface systems. It operates at two selectable input voltage ranges and can be used worldwide, within compact dimensions. To protect the relatively thin wires of the AS-interface cable and the connected components, the output circuit features an electronic fuse, which permanently switches off the output in the event of a failure.

The easy-to-set front-face jumper allows the assignment of new ID addresses to slaves by means of an external infrared programming unit without disconnecting them from the AS-interface cable.

Up to 62 binary I/O devices can be connected and supplied according to the AS-interface bus technology with a single two-conductor cable. The communication signals are modulated onto the slaves’ DC supply voltage of the AS-interface system, which therefore requires a specific power supply with integrated data decoupling.

Operating mode

By means of the input voltage selector the input voltage can either be set to 115 V AC or 230 V AC. The front-face jumper allows the configuration of the operation mode of the power supply, i.e. “1-2 COMMUNICATION MODE” or “2-3 IR ADDRESSING MODE” to either control and supply AS-interface slaves or to interrupt the data communication for the assignment of new ID addresses to slaves by means of an external infrared programming unit.

In the event of a failure, the integrated electronic fuse permanently switches off the output to prevent an accidental restart. The front-face button RESET allows the intentional reactivation of the power supply.

The green LED “AS-I OK” is on during normal operation, i.e. when the output voltage exceeds 30 V DC, and is off at overload.

The red LED “IR ADDRESSING ON” is on when data communication has been interrupted by means of the jumper.

The red LED “OVERLOAD” is flashing after having triggered the integrated electronic fuse of the output circuit in the event of overload, short circuit or overtemperature.

Installation

The device must be installed by qualified persons only and in accordance with the specific national regulations (e.g. VDE, etc.). The devices are maintenance-free chassis-mounted units.

Before installation

DANGER!

Components with high stored energy and circuits with high voltage

Danger to be electrocuted!

Disconnect the system from the supply network and protect against switching on before any

installation, maintenance or modification work.

Do not introduce any objects into the unit and do not open the unit.

Ensure that the service personnel is protected against inadvertent contact with parts carrying energy.

Mounting

The switch mode power supply can be snapped on a DIN rail (TH 35-15 or TH 35-7.5 according to IEC/EN 60715) as shown in the accompanying picture. For that the device is set with its mounting rail slide on the upper edge of the mounting rail and locked by lifting it downwards.

Demounting

Remove the switch mode power supply as shown in the accompanying picture. For that the latching lever is pulled downwards by means of the screwdriver. Alternatively the upperside of the latching lever can be pressed to release the device. Then in both cases the device can be unhinged from the mounting rail edge and removed.
