Thruster monitoring and control system Jastram

Drawing on experience in thruster drive and control systems since 1950 Jastram offer a wide range of applications:
3-step drive systems with resistor units and slip ring motors have been the most popular drives over the last few years.
Dynamic drive, a multistep drive system with resistor unit, slip ring motor and reduced starting current, is the cost-competitive alternative to controllable pitch propeller (CPP) thrusters with the advantages of the robust fixed pitch propeller (FPP).
Frequency-controlled (FC) drives accommodate the increasing demand for stepless control. Interfaces to joysticks and dynamic positioning systems as well as any other customised application can be realised by Jastram.
