The TM-30 is a medium power level, 1,250 Vac drive. Three converter types are available, a diode non-regenerative type, a thyristor regenerative type, and an IGBT regenerative type.
The inverters are IGBT-based with heat pipe cooling and exhaust cooling fans. The three power bridges are modular on heavy duty slides that reduce the time for maintenance.
The output frequency is variable from 0 to 120 Hz, and power levels up to 4,000 kVA are available.
