Rexroth KDV 1.3-100-200/300-115
The KDV 1.3-100-200/300-115 is an AC power supply that can work with up to 10 drives and their associated motors. It rectifies three phase AC and provides regulated DC power for your drive system. It can operate at a continuous mechanical rate of 24 kW.
Energy generated by braking is fed back into the mains, and buffers provide smoothing. That means that the KDV 1.3-100-200/300-115 can tolerate brief power outages. It’s also ideal for applications requiring high continuous regeneration power.
Since its heatsink is mounted at the back of the module and outside the cabinet, the KDV 1.3-100-200/300-115 allows a smaller cabinet footprint and saves on cooling costs.
Add-on components include a smoothing choke, a commutation choke, a link capacitator, and a bridge capacitator.
When you need support
If you’re using a KDV 1.3-100-200/300-115 as the power supply for your drive system, chances are good that you are using other legacy parts along with it. Fortunately, Rexroth continues to support legacy systems with factory repair and reman.
You can’t go out and buy a new KDV 1.3-100-200/300-115. You also can’t expect your local fix-it shop to have experience with the KDV 1.3-100-200/300-115. They will not have access to original parts or schematics.
The cost of a failure of your power supply obviously includes the cost of repairing or replacing the module. However, it also includes the cost of your downtime while you find and compare repair companies, send the unit out for repair, and get it installed and configured again. These costs are usually larger than the cost of repairs.
Unfortunately, we often see people using trial and error to choose a repair option, often spending weeks trying various possible solutions while downtime racks up thousands of dollars in costs. The bargain choices quickly become the most expensive decisions you could make.
Instead, you should call us first. We will provide phone support, field support as needed, and replacement units to keep you working while repairs are completed.
