Mounting Without Cooling
For any DES 410 and for DES 411 Power Supply providing an excitation current up to 5A included
(dynamometer models 1Wb/Pb 65, 2Wb/Pb 65, 1Wb/Pb 115, 2Wb/Pb 115 and 1Wb/Pb 15),
a cooling plate is not required
The power supply can be mounted on a support fixed to the table or directly to the test bench. An
example of such mounting is given in
