to countries with different grid standards (50 Hz, 60 Hz) or
for aviation and military devices with 400 Hz supply
frequency.
 frequency: 50 Hz, 60 Hz, 400 Hz, or
according to customer requirements
 voltage: according to grid standards in the
target country, or according to customer
requirements

7. GSE – Peak energy generator
 delivery of peak energy to company grid
 coverage– reduction of quarter hour maximum
 coverage – reduction of technical maximum
 Li-ion batteries
 IGBT equipped inverter
 high quality of generated voltage
 THDu ≤ 1 %, THDi ≤ 3 %, cos φ = 1
 power: 40 and 100 kVA
 project – production – installation - training

8. ACSW – thyristor switches
Thyristor switches – replacement of “classic” switches
 Voltage: 3 x 400 V
 Current: 72 – 100 A
 dynamic power factor correction
 smooth switching of capacitive load without current peaks
 switching in “zero” voltage, short switch-on time
 very long life-span, due to “unlimited” number of switching cycles
Typical applications:
 lifts
 cranes
 welding machines

9. Uninterruptible and backup power
supplies
