1.1. General description.
The PSU is designed for supply of up to 4 webcams requiring stabilized voltage of 48V DC.
The output
voltage can be adjusted with a potentiometer between
42V÷54V DC. There are 4 power supply outputs,
independently protected by melting fuses or PTC polymer fuses. Failure (short circuit) in the output circuit will
activate the melting fuse or PTC fuse and disconnect the circuit from DC power (+ U). Fuse failure is indicated by
switching off the corresponding LEDs: L1 for AUX1, etc. In addition, the FPS output (hi-Z state) and LFPS LED are
activated and the relay contacts change their position. The PSU is housed in a metal enclosure with signaling panel
equipped with a microswitch indicating door opening (front cover). The power is carried over the spare pairs (4/5 &
7/8), which, according to the Ethernet network standard, are not used for data transmission (data transmission
uses 1/2 and 3/6 data pairs).
The PSU can not be used in Gigabit Ethernet networks, where all twisted pairs are involved in the
transmission of data!
