1. Technical description.
1.1. General description.
The PSU is designed for supply of up to 8 webcams requiring stabilized voltage of 48V DC(+/-15%). The PSU
supplies voltage of 54V DC and total current capacity of I=8x0,3A+0,2A Battery charging*. In case of mains power loss,
the unit will instantly switch to battery operation. There are 8 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!
During normal operation, the total current drawn by the device should not exceed I = 8x0,3A
*
.
Maximum battery charging current is 0,2 A. Total current of the receivers + battery is max 2,6A.
