1. Technical description.
1.1. General description.
The PSU is designed for supply of up to 4 webcams requiring stabilized voltage of 24V DC(+/-15%). The
PSU supplies voltage of 27,6V DC and total current capacity of I=4x0,4A+0,2A Battery charging. In case of mains
power loss, the unit will instantly switch to battery operation. 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!
During normal operation, the total current drawn by the device should not exceed
I = 4x0,4A. Maximum battery charging current is 0,2 A. Total current of the receivers
+ battery is max 1,8A.
