Function
The VAN-24DC-K28 DC/DC transducer was designed for field bus applications, which transmit both energy and data via a two-wire cable
(AS-Interface design). It powers a fully loaded AS-Interface system with a maximum output current of 30.55 V and 4 A.
In this case, the DC/DC transducer provides the energy, decouples data of the power source and balances the two output cables
(AS-Interface + and AS-Interface -) in relation to ground (screen connection).
The precise and transformer coupling permits the use of unshielded load lines.
The PELV output circuit is electronically protected against overload and continuous short circuit.
Fusing:
The DC/DC transducer is electronically protected against continuous short circuit. In case of a defect, the internal fuse disconnects the DC/DC transducer from the power supply.
