Siemens 22 → 29V dc Input DIN Rail Uninterruptible Power Supply (360W), SITOP DC

Use this uninterruptible power supply from Siemens as a reliable source of backup energy. It provides power to connected devices in the event of a sudden loss of supply. This helps your equipment to continue to function without suffering negative effects. As this is a DC-type module, it's practical for applications involving your computer or other battery-driven, memory-based hardware. You can use it with input voltages anywhere from 22 to 29V DC and get a steady output voltage of 24V DC. Thanks to the unit's short-circuit protection, you're reliably shielded from the risk of shocks caused by excess current.

• LEDs provide clear status indication for easy troubleshooting
• Reverse polarity protection prevents damage to UPS in case polarity of supply is reversed
• IP20 rating makes it touchproof and resistant to objects larger than 12mm
• Snaps onto a DIN rail without any need for tools, so easy to install

This UPS's efficiency rating of 96.2% means it wastes little energy as heat and relies on natural air convection for cooling, so there's no need for a heat sink.
