Energy storage system - max. 800 V | DES 3.0, DES 4.0
Other devices with higher load capacity - approximately by a factor of 1.5 for the DES 3.0 and about a factor of 2 for the DES 4.0. Thus, while the Dynamic Energy Storage DES 2.0 can store and deliver about 800 watt-seconds in a cycle lasting one second, the new DES 3.0 can store about 1,200 and the DES 4.0 can even store some 1,600 watt seconds. Or vice versa: The new devices can store high amounts of energy and then release it again in a shorter amount of time. With similar exterior dimensions, these high capacities are achieved by modified electronics and significantly improved active cooling systems. Similar to the DES 2.0, the DES 3.0 has a standard energy storage device with about 1,600 watt-seconds while the DES 4.0 depends on external expansion modules (types EM 2.0). Both devices are conform with the requirements of UL.The new devices DES 3.0 and DES 4.0 have self-teaching properties, similar to the DES 2.0. This means that they only require three cables to be connected to the respective DC link and the braking chopper output of the drive inverter and you are set to go i.e. no configuration, commissioning procedures or even programming this is incredibly simple, but true. Advanced planning is required in advance to analyse the application carefully. This means that the correct power for the device and the storage capacity can be precisely defined and used. It only remains to connect the DES to save electrical energy.
