Your comms cabinet is shallow. Wall-mounted. No room for a desktop tower UPS crammed behind the patch panel. But your switch, router, and PBX still need clean, stable power when the grid stutters.
The PowerShield Defender Rackmount 1500 was built for exactly that space. At 86mm deep (438W × 300D × 86H mm), it slides into a standard shallow rack or sits flat in a wall-mounted comms cabinet without eating your cable management room. 13.8kg – manageable on its own.
Line-interactive AVR smooths out the voltage dips that brown-out your switch at 5:45pm every Tuesday. Two 12V/9Ah long-life batteries (8–10 year design life) mean you're not swapping cells every 18 months. Best-in-class surge protection is included. 2-year warranty
