7.1 Triple power supply
The ATSC25 can be supplied by 3 power sources:
AC
– Power through the voltage sensing (terminals 103-104 for source 1 and terminal 203-204 for source 2) with power
supply range going from 184-300 V.a.c (in pulse mode) 200-300 V.a.c (in maintained mode) 50/60 Hz+/- 10%
DC - Auxiliary supply (optional), 10-30 V.d.c power supply using terminals 82-81.
7.2 Voltage sensing Inputs
The ATSC25 includes dual single phase and 3 phase voltage sensing (terminals 103-106 and 203-206) designed to monitor 1
Phase supplies up to 300 V.a.c (L-N) and 3 phase +N up to 520 V.a.c (L-L).
The ATSC25 is designed to handle single phase and three phases with neutral networks, simply define the correct
configuration of single phase / 3phase with neutral using the DIP switch 1 on the front of the controller (cf. Chapter 7-5
programming).
Sensing values measured will have a direct influence on determining the availability of the main and alternate supplies as well as
the ATSC25 automation.
The parameters monitored through the sensing are the following:
7.3 Phase rotation
When both sources are available the controller will check that the phase rotation is identical on both sources. If the sources have
different phase rotations the source available LED will be blinking on both sources.
7.2.1 Frequency within set limits
The ATSC25 will check that the frequency is within the limits configured through DIP switch 4 or through communication (cf.
configuration chapter configuration). Frequency is checked on L1 only.
7.2.2 Loss of the main or alternate power supply
Loss of supply depends on the nominal voltage and frequency configured together with the hysteresis (set in DIP switch
4)The source will be considered as lost after the fail timer as counted down (set through dip switches 7 & 8 (0 / 3 /10 / 30
min).
7.2.3 Return of main and/ or alternate power supply
Return of supply depends on the nominal voltage and frequency configured together with the hysteresis set. (Set in DIP
switch 4). The source will be considered as available when the return timer will have counted down (set through dip switches
6 (3s / 10s).
7.2.4 Loss of Neutral
In a 3phase network with unbalanced loads the loss of the neutral will be detected.
The DPS output to the RTSE will not be functional when powering
through the DC auxiliary power supply.
CAUTION
When only one source is available, the controller will
automatically
accept the source regardless of the phase rotation order
