The UPSIC-2403D in a compact DIN rail housing protects connected consumers against fluctuations and interruptions in the supply voltage. Maintenance-free supercaps provide for an extremely high cycle stability and short charging time. Intelligent power sharing does not require the source to be overdimensioned to load the supercaps. In addition, the UPSIC-2403D offers an active reverse polarity protection, a power fail signal via a relay contact and a free software with timer function. The built-in reboot function allows the system to restart if the input voltage returns during shutdown or at any other time. The BIOS can be used to enable the boot function when the input voltage is present. In addition, it can be set via a dip switch that the output of the UPS is only enabled when the capacitors have reached over 90% of their charge. Operation of the UPS on the host is also possible without software.This text is machine translated.
