The new Jumo power unit consists of two self-contained device versions: type TYA-201 for single-phase operation and type TYA-202 for three-phase operation in a three-phase economy circuit. Due to the LC display with plain text that is provided as standard, configuration can be performed quickly on the device. The menus are clearly and legibly structured, so that users rapidly become confident in handling the system, thus reducing initial setup times. Thanks to its new structure, a slim-size device is now available, with current ranges from 20 A to 250 A. Pre-configuration is simple and uncomplicated via a mini USB connector at the front. There is no need to connect the device to an additional supply voltage, as power is supplied via the USB port available on a PC or laptop. The new “teach-in” function is a self-learning function, used to automatically set the limits for partial load failure detection. Cyclic adjustment means that partial load failure can be permanently and accurately detected, even if the characteristics of the heating element change.
