General Description
The LightMaster PPS640-KNX is a regulated KNX bus power supply with an
integrated BUS choke, designed to provide network DC supply to the KNX
network. The switchmode design allows the device to be used with a wide range of
supply voltages without the need for a manual selector setting. The PPS640-KNX is
housed in a 4 unit DIN rail mount enclosure that has a circuit breaker prole. This
enables the device to be installed in all types of electrical equipment enclosures,
including those with cover apertures specically designed for circuit breakers.
