Meaning
Low Voltage. Voltage level up to 1000 Vac or 1500 Vdc.
Medium Voltage. Voltage level between 1 kVac and 35 kVac.
Power Conversion System 120. PCS120 is the product platform for the ABB power condi-
tioning products.
Power Electronic Building Block.
Platform Enclosure 120. PE120 is the enclosure that contains several PEBB modules. The
product has three enclosure designated as PE120-1, PE120-2 & PE120-3.
Direct Current Termination. DCT is an enclosure where the energy storage cables are ter-
minated and connected to the MV UPS PE120 cabinets.
Auxiliary Power Supply. APS is an enclosure that contains the MV UPS switched-mode
power supplies, remote input/output modules, control circuits and auxiliary transformer.
Isolating Line Reactor. ILR is a medium voltage impedance connected in series, between
the grid and the load.
Coupling Transformer. CXF is a transformer that couples the medium voltage network to
the low voltage power converters.
Input Switch. Represents the designation of the input circuit breaker connecting the MV
UPS to the grid.
Output Switch. Represents the designation of the output circuit breaker connecting the
MV UPS to the load.
Automatic Bypass Switch. Represents the designation of the bypass circuit breaker that
by-passes the MV UPS system and connect the grid directly to the load. This breaker is au-
tomatically controlled by the MV UPS.
Power Conditioning Mode. When operating on this mode, the MV UPS continuously condi-
tions the load voltage.
Independent Mode. When operating on this mode, the MV UPS disconnects from the grid
by opening the input circuit breaker and supplies the load through the energy storage.
The term is used to describe the system in bypass (not operating). When working in by-
pass mode, the bypass breaker is closed, and the input/output breakers are opened.
Main Controller. Universal controller located in the PE120-1 enclosure.
Universal Controller.
Two HUB controllers are located in PE120-2 and PE120-3 cabinets respectively. The main
function is to transfer the information to the main controller.
