Description
The Power Supply KNX PS640 4U is a 640 mA KNX bus power supply to supply one TP line of a KNX system with power. The KNX PS640 4U also features an additional unchoked output. This auxiliary output can be used, for example, to supply a second line (only with additional choke). Devices which require a second supply voltage can be supplied. Both outputs are overload-proof and short circuit protected.
The KNX bus can be reset by push-button. Bus disconnection during reset is indicated by a LED. Further LEDs, for KNX bus voltage and total output current, indicate normal operation and overload.
