EA Elektro-Automatik - News
With the ELM 5000 series EA Elektro-Automatik has developed a new range of programmable electronic DC loads with energy recovery. The ‘M’ in the product name stands for the modularity of the series: up to 10 modules may be combined in a 19” cabinet with 6 HE.
Up to 94% of the absorbed power is fed back by the system into the supply net. Thus DC sources such as power supplies, solar modules, batteries and other energy storage media can be tested in an environmentally friendly way together with power saving in function and burn-in tests. The user can choose between two models: the electronic load ELM 5080-25 with 80V, 25A and 320W or the load ELM 5200-12 with 200V, 12A and 320W. To increase performance loads can be switched in parallel. The system is flexible: the chassis can be populated with different modules. Control and monitoring of the equipment is enabled via an Ethernet port. Furthermore, load processes can be loaded or logged via a USB stick. Thus tests may be simply programmed and recorded.
Intuitive operation using a TFT touch panel
The devices are operated using the high definition colour TFT touch panel of the HMI, intuitively and in multiple languages. The display shows concurrently actual values for voltage, current and power. Moreover the user has a view of set values, the control mode, alarms and warnings together with the input status.
