Why PS 100 ?
● The “PS 100” unit supplies back-up operating power for :
• MV switchgear electrical mechanism ( motors and coils )
• Transmission equipment ( e.g radio )
• Protection relays , Fault passage indicators or others IEDs
• And all others devices in MV/LV substations (LV breakers, PLC concentrator..)
● The “PS 100” has been designed for supplying power in distributed
architectures ( SC110A, Flair 23VD, VIP410, Sepam…) to fit in LV cubicles of SM6,
Premset * …
* New MV switchgear range (ex- Matrix project)
● The “PS 100” will offer a new elegant solution in application in current MV/LV
substations without RTU ( Remote Terminal Unit)
- is integrated in Advan6 wave 3
- in repetitive MV/LV substation with SM6, MH 24+, FBX & RM6 (3 or 4
functions)

Autonomy
● Autonomy up to 24 hours
● Depend on
● Mainly the permanent Load (PL)
● the “Energy backup” (Pb)
● The type of battery (38Ah, 24Ah)
● Temperature
● Battery age
● The non permanent load is estimated
to 16 Open&Close cycles of
Switchgear. (Ps)
I.e : 4 operating Sepam10 (4x8=32 W)
allows 12 hours of autonomy
● PS100 Autonomy

PS100 supply capacity
● 3 examples of maximum number of
devices for 1 PS100:
CB with
protection
relay and
motorization
Switch with
Fault
detector and
motorization
● 1 PS100 supplies up to 2 protection
relays or 16 switches
ATS with 2 SW

● With 3 or 4 protection relays, it is
recommended to use 2 PS100 with
redundancy
● With an Automatic Transfer Switch
device, it is recommended to use a
second PS100 for protection relays.
● For more than 4 Protection relays ,
PS100 isn’t usable

Benefits
Optimized battery backup
● Only one battery to simplify the replacement
● The PS100 needs only one battery, simplifying replacement vs traditional
backup power supplies require a set of 2 or 4 batteries to produce 12V or
48V, with complicated replacement and adjustment of the battery pack.
● Battery can be purchased easily, anywhere in the world : sealed lead 12V
battery ,10 years life
● To prevent power network cuts
● Enables output voltage backup in case of cuts up to 24 hours
● PS100 protects and optimizes the battery duration
● Ensures its charge with a regulated and temperature-compensated charger
● Checks the battery and prevents the battery deep discharge level
● Measures battery ageing and alarms before battery end of life

Benefits
High availability
● PS100 is robust to the harsh environment of electrical substation
● Reliability is a key point for Electrical substations :
Insulation: 10 kV,
- 40°C to +70°C operating temperature...
● Electronic protection against over voltage, overloads and short circuit
● Automatic restart after fault
● Additional “Energy back up” to restart the installation after a prolonged network
cut
● an optional Energy back up can be enabled with a local push button to provide
energy for restarting the protection relays and electrical control of MV
switchgears at installation restarting.
● Forecast backup reservation : 300 W - 1mm
●
Modbus communication port forwards monitoring data to allow optimized
maintenance operations.
● A limitation, dedicated for radio units, is set up to avoid the battery deep discharge
