3. 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)

11. 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

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

13. Optimized battery backup
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

14. Benefits High availability
PS100 is robust to the harsh environment of electrical substation
Reliability is a key point for Electrical substations :
Insulation: 10 kV, °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

15. Redundancy to increase availability and power
