Phoenix engineer Liang You looks on during a field test as geophysicist Yann Avram and technician Steve Wilton easily lift the new light-weight TXU-30, also shown in the inset.
The new TXU-30 multifunction geophysical transmitter has several advantages over previous-generation technology. It is compatible with any suitable motor generator, is very energy efficient and is 60% lighter; it also has a separate control panel with a 10-metre cable, permanent GPS synchronization and automated frequency sweep. Many units have been ordered, and deliveries to clients will begin soon.
Any suitable MG can be used: the most important improvement allows the TXU-30 to be powered by many different motor generators, including the 400kg Phoenix MG-40A 400 Hz/3 Phase/208V 40kVA motor generator which is popular because of its high power-to-weight ratio.
Any other 400Hz/3 phase/208V to 240V unit (such as the Hobart 400Hz aircraft GPUs) can be used. As well, any suitable 50Hz or 60Hz three phase/208 volt unit can be used.
Energy efficiency: The actual output power of the TXU-30 is limited by the MG unit. For applications requiring only low power, an MG unit as small as 8 HP (5 kVA) can be used (for example, the Honda EZ3500C). The high efficiency of the TXU-30 electronics means that little energy is used for internal control, and most of the MG
