MG060 frequency inverter 50=>60 Hz (rotating), power from 12,5 to 709 kVA
In the converters, asynchronous motor and brushless synchronous generator are arranged on a particularly compact base frame with coupling and vibration dampers. The robust arrangement of the components leads to a high level of operational reliability with complete freedom from maintenance. The electronic frequency inverter is supplied in a ready-to-use setting and is generally provided for installation of switchgear cabinets.
The installation shall consist of:
three-phase motor IE4 (up to 315 kVA), after DIN EN 60034-1
✪ 3AC-Synchrongenerator
Frequency inverter (electronically vector-controlled) for switchgear cabinet installation
. with temperature monitoring
. with EMV filter
. optionally with intermediate circuit inductor
. with control panel for the switchgear cabinet door
✪ Multifunction measuring instrument with real root-measurement incl. current transformers
✪ Base frame 2-fach including vibration dampers
Coupling with protective device for laser-oriented machines
In the case of single-phase loads, it is important not to exceed the phase current.
The voltage and frequency can be adjusted by a built-in trim potentiometer or optional external potentiometer (about ±10% adjustable, power is reduced). The generator can be switched by 12 clamping on the generator terminal board.
Characteristics:
ᐅ Output voltage and frequency (45-65 Hz) continuously variable
ᐅ input voltage variable
ᐅ low output frequency tolerance and good sine through vector control
ᐅ The system contains many standard parts and is therefore very cost-effective
ᐅ Brushless operation and therefore maintenance-free
ᐅ Network decoupling of consumer load surges
ᐅ Soft start-up, no x-times the starting current
ᐅ Bridging short grid outages
ᐅ Energy savings function
ᐅ Automatic voltage regulator with three-phase actual value measurement for unsymmetric loads

Documentation in German
Components from Siemens, Wöhner, Wago and Rittal are mainly used.
The trade fair council displays the measured values validly at the switch cabinet location.
Please consider u.U. a voltage drop in the case of long connection lines to the loads.
Scope/Notes
• The plant serves as a AC- source for the transmission of electrical power
from the network to AC- consumers with frequency and voltage independent of the network.
• Installation in the industrial sector in production facilities
Limited access/position on concrete or non-combustible floor
• No safety consideration was carried out.
• For the risk assessment, taking into account local conditions
The operator/user is responsible.
• The offer/delivery does not include installation/connection cables, including switchgear cabinets for the generator unit.
The offer is without placing, assembly and commissioning. Not including electrical switchgear. The terminal boards are interfaced in the terminal box or, if necessary, also in the switchgear cabinet. The generator/converter can reach a sound pressure >80 dB(A). Suitable sound protection measures in accordance with the legal provisions must be ensured by the operator.
