NOTE:
All DES 41X Power Supplies include the corresponding dynamometer connection cables. The last digit of the part
Number refers to the cable lenght in accordancewith the following table.
If the DES is ordered separately (from the dynamometer), it is absolutely necessary to specify which model of Eddy-current/
powder brake will be used with the DES power supply in order to limit the operating current and prevent possible damage to
the dynamometer brake. Mains voltage (115 VAC or 230 VAC) should also be defined when ordering.
