EA Elektro-Automatik 台式电子负载
EA Elektro-Automatik 台式可编程直流电子负载系列有台式和塔式两种外形，功率范围为 300W 至 1500W。部分型号具有自动量程和内置函数发生器等高级功能。自动量程功能可在电压较低时自动调整为高电流，反之亦然，在各种电压/电流水平下都能保持全耗散功率。函数发生器可提供多种波形，如正弦波、三角波、矩形波和梯形波，还可驱动定自定义的任意波形，以实现动态加载。
所有台式负载均配有 TFT 触摸屏，便于直观的控制和测试设置。其界面简单易用，可快速配置测试并直观地操作仪器。EA 台式和塔式系列直流电源和负载结构紧凑，节省空间又经济实惠，并且具有市场上大多数台式设备所不具备的先进功能。
高达 30 千瓦
高达 2000 伏
高达 1000 安
Autoranging Gives Flexibility
EA Elektro-Automatik products have autoranging, which allows the supply or load to operate at max power across a range of voltages and currents, down to 33% of the rated output maximum.
Compare this to traditional power supplies, which can only output their rated power at their max voltage and max current. Applying the maximum voltage to a device under test (DUT) is rare, which means most of the time, that supply is not being used to its full potential.
How does it work? EA sources automatically offer more current at lower voltages (or more voltage at lower currents), allowing the supply to continue outputting the rated power. This allows a single source to address multiple voltage and current combinations that would otherwise require multiple supplies.
Regeneration turns waste into savings
EA regenerative electronic loads and bidirectional supplies can recover up to 96% of the energy they sink, that means the AC mains connection is also used as output for the back-feed of the supplied DC energy.
Traditional electronic loads or resistor banks dissipate their sunk power by turning it into heat. This can require large cooling/HVAC solutions and that sunk energy is then lost forever as waste, reducing test and facility efficiency.
Energy recovered by EA loads is fed back into the local facility grid with a mains-synchronized inverter, where that energy can be used by other devices in the facility. If more energy is recovered than used by the facility (a possibility when testing fuel cell output, for example), the energy can be fed back out to the public grid.
