Rexroth Indramat manufactures the HVE02.1-W018N 2nd generation power supply unit. It is part of the drivesystem where it is used to supply electricity to HDD and HDS drive controllers. It allows the operation of several drive controllers simultaneously. The power rectifier in the HVE02.1-W018N provides unregulated DC bus voltage by rectifying the 3-phase AC voltage from the mains supply. It can run in a generator mode where it produces heat via a bleed resistor. You can use it to shut down motors with a permanent magnet energizing by the short-circuit bus. Thanks to the integrated monitoring functions, it monitors and optimizes the drive system.
The HVE02.1-W018N can only be used with the accessories and parts specified by Rexroth Indramat. It should be operated under installation and ambient conditions which are a maximum installation height of 1000 meters above sea level, ambient storage, and operating temperatures of -30 to 85 degrees and 5 to 45 degrees respectively. The permissible relative humidity is capped at 95% without condensation. The power loss characteristics include basic losses of 125 kW, 250 W loss at the maximum continuous output, and 7 W/kW power losses per kW DC bus continuous power.
The HVE02.1-W018N features a weight of 13 kg and an IP 10 protection category. The input voltage ranges between 3 x 380 … 480 V and the frequency range is between 50 and 60 Hz. Ensure that the air within the control cabinet is free of dirt. It is possible to connect DC bus chokes of the GLD type to the HVE02.1-W018N to increase the DC bus continuous power. You can connect the HZKcapacitancemodule to reduce heat loss and to increase the power in case of power failure. This product is available from Wake Industrial with a one-year warranty period.
