About This Product

■SummaryThyristor Leonard devices have been manufactured and used by customers since the late 1960s as power supplies for driving DC motors. On the other hand, DC motors continue to operate due to their robustness. As DC motor drive power supplies, we provide customers with products that are compact in appearance and contribute to stable operations.

■Easy maintenanceThis enables front-line maintenance of major parts. The intake air filter can be replaced from the front, making maintenance easy. It is also easy to replace the pressure ventilation fan.

- Air filters can be replaced by simply removing two screws.
・You can easily remove the pressure ventilation fan by pulling up the handle.

■ReliabilityThe main circuit uses a thyristor, which has been proven since the 1960s, and the control circuit follows an analog control circuit.

■Long lifespanLonger life has been achieved by using a film capacitor in the snubber circuit.

■Space saving- Compact design.
・Installation area Width: 700mm x Depth: 550mm

■Convenient optionsWe have prepared a "Fault Trace Function" that facilitates failure analysis and shortens MTTR*1. *1 MTTR: ​​Mean repair time

■FeaturesThe DC drive device uses a main circuit that uses a highly reliable and long-life thyristor.

■ApplicationsIndustrial use such as steel, paper/pulp, etc./cableways, cranes/test equipment, etc.
