Inverter with VE Direct communication interface. Thresholds for shutdown and restart at low battery voltage levels. Dynamic shutdown: load-dependent shutdown threshold. Output voltage 210 - 245 V. Frequency 50 Hz or 60 Hz. Threshold for ECO mode on/off and ECO mode sensor. The complete bridging with an additional ring transformer topology has proven itself over the years. The inverters are short-circuit proof and protected against overheating (whether due to overload or ambient temperature). This is necessary for powering devices such as voltage converters for LED lamps, halogen lamps, or power tools. In ECO mode, the inverter switches to standby mode as soon as the load falls below a preset value. In standby mode, the inverter then turns on for a short time (adjustable preset: every 2.5 seconds). If the load exceeds a preset threshold, the inverter remains on. A remote on/off switch can be connected with a two-pole plug or between the positive terminal of the battery and the left contact of the two-pole plug, and for our low-power inverters, we recommend our Filax Automatic Transfer Switch. With the Filax, the switching occurs very quickly (in less than 20 milliseconds), ensuring uninterrupted operation of computers and other electronic devices.
