The Model AC2267-TC_ is a two axis, high precision test stand equipped with a large temperature chamber. The size of the useful chamber volume permits the testing of several UUT's simultaneously. Since most of the test time is used reaching or dwelling at defined temperature levels, testing multiple units reduces the test and calibration cost considerably.
The table offers excellent instantaneous rate stability and precise and stable positioning. High precision encoding is achieved by industry standard position transducers. The systems are fitted with direct drive brushless motors offering high torque and therefore high accelerations. A wide variety of motors allows adjusting the torque capability according to customer requirements.
While the standard 52 line slipring capsule offered can meet most customer's needs, testing multiple UUT demands large slipring capsules with special connections which the customer must define.
