Inverter FRENIC MEGA Series Specifications: 400 VAC
FRENIC MEGA is the new High Performance inverter from Fuji Electric and is the successor of G11S inverter. The capacity range of FRENIC MEGA is for 3 ph 400 V supply from 0.4 kW to 630 kW and for 3 ph 200 V supply from 0.4 kW to 110 kW. The overload capacity of FRENIC MEGA is 150% for 1 min and 200% for 3s (in High Duty mode). The inverters with capacities of 5.5 kW and above can be used in dual rating; this means that the same inverter can be used for next higher capacity (in Low Duty mode). For example a 5.5 kW inverter can be used for a 7.5 kW motor; in this case the overload is 120% for 1 min. The braking transistor is included as standard up to 22 kW units and is optional up to 110 kW units. The braking resistor is included as standard up to 7.5 kW units.
The main features of FRENIC MEGA are:
1. Safety enable input (compliant to EN954-1 category 3)
2. Built-in EMC filter for all capacities (compliant to EN 61800-3, category C3)
3. Sensorless vector control mode (100% torque at 0 Hz)
4. Advanced PID functions (dancer control)
5. Brake control function
6. Logic gates for logic combination of input and output functions and delay timer (10 steps)
7. Positioning function (when encoder option is used)
8. 3 slots for 3 different options at the same time (encoder, fieldbus, I/O expansion)
9. Removable control terminals (cage clamp type)

Note:
*1 Fuji 4 pole standard motor
*2 Rated capacity is calculated assuming the rated output voltage as 220 V for 200 V class series and 440 V for 400 V class
series.
*3 Output voltage cannot exceed the power supply voltage.
*5 Voltage unbalance (%) = (Max voltage (V) - Min voltage (V) / Three-phase average voltage (V)) × 67 (IEC61800-3)
If this value is 2 to 3%, use an optional AC reactor (ACR).
*6 Required when a DC reactor (DCR) is used. A DCR is provided as standard for LD-mode inverters with a capacity of 55
kW and inverters with a capacity of 75 kW or above.
*7 Average braking torque for the motor running alone. (It varies with the efficiency of the motor.)
*8 380 to 440 V, 50 Hz; 380 to 480 V, 60 Hz
*9 For inverters with a capacity of 55 kW, a DCR is provided as standard or option for LD or HD mode, respectively.
