Which one for what
The clean decision guide for common Indian B2B scenarios. Pick the row that fits.
Core banking server room, 10-20kVA three-phase
Either brand clears the spec. Eaton’s Intelligent Power Manager gives tighter visibility if your ops team already runs VMware or Nutanix.
Space-constrained branch with rack depth under a premium
Delta’s Amplon RT ships in a compact 2U footprint with unity output power factor, matching Eaton’s DXRT on density. Check depth clearance on both before committing to a rack.
Multi-site rollout with a Li-ion battery preference
Delta’s external Li-ion battery cabinet is a standard catalogue option on Amplon RT. Eaton offers Li-ion on select 5PX/9PX SKUs but it isn’t the default across the range.
BFSI branch needing a fast, written on-site response commitment
Both brands route through Sirius Star’s single-window support. Ask us for the branch-by-branch response time in writing before you sign.
Budget-sensitive single-phase server room
Delta’s single-phase RT series typically prices sharper at the same kVA band. Eaton’s 9E series is the comparable single-phase counter.
