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:
1. Output current 4x1A + 0,5A battery charging
2. Output current 4x0,87A + 2A battery charging
Total current of the rec battery is max. 5,5A
*
.
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 L
FPS
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!
