The SPS SH500IN is a line-interactive uninterruptible power supply designed to keep your equipment running during power outages. It provides an output capacity of 500 VA and can handle a maximum load of 500 W, converting a 12 VDC input into a stable 230 V output for your devices. Housed in a durable black metal case, the unit features two Schuko outlets to connect your hardware. You can easily monitor its status via the integrated LCD display and manage the system using the reset button, while an internal cooling fan prevents overheating during operation. Because this model relies on an external battery rather than a built-in one, it is well-suited for users who want to customize their backup time by connecting their own power source.
