RTAC01 pulse generator evaluation Slide 25 DCC Cranes amp。 Components dep. 1205 Prein Functions Standard inputs/outputs ? 10V reference output。 Components dep. 1205 Prein Dedrive Pro Braking resistors For hoist applications, a resistor capable of continuous resistance (100% CDF) should be selected if the duty factor either cannot be specified or the specified duty factor can be exceeded in individual cases. If the cyclic duty factor is known (regenerative operation ? motor operation / break), an overloadresistant braking resistor can be selected when dimensioning the resistor. Slide 19 DCC Cranes amp。 Components dep. 1205 Prein Dedrive Pro Determining the inverter current Iinverter = 1,11 * fH * fT * fF * fRV * Idrive fF = Output filter factor fF = 1 No output filter = 1,05 With an output filter The temperature and site altitude factor are determined in the same way as for the output.

The max. inverter current is not reduced in this case. Inverter effective output: Pmax, req. = fH * fT * fU * Pmax, drive, el. fU with Unom, inverter = Device rated voltage (400V, 500V or 690V) Umin = minimum operating voltage
