Siemens Redundancy module, SITOP PSE202U Series

When you want fail-safe power protection against faults or outages, get the job done with this redundancy module from Siemens. It lets you decouple parallel power supplies from one another. This stops mains failures or electrical faults like short circuits in their tracks and prevents them from affecting multiple devices. That means if a single PSU fails, the other will take over to provide the energy you need to safely shut down critical applications or save important documents. The product's isolated output protects people and connected equipment in case of overloads or current surges.

• Saves space in a control cabinet thanks to compact dimensions of 30 (L) x 80 (W) x 100mm (D)
• Supplies connected by a SELV circuit for a high level of electrical safety
• Handy LED indicators give you easy-to-read diagnostic info
• Uses natural air convection to keep cool, so there's no need for a heatsink
• Broad operating temperature range of -20°C to +70°C, so suits use in harsh environments

The module's screw terminals let you connect any wire up to 2.5 mm², so it's a versatile choice.
