3S700D Eaton 700 700VA VFD (Off-Line) UPS/USV

Compact Off-Line UPS for Edge and Workgroup Power Continuity with the 3S700D

The 3S700D is an Eaton 3S Gen2 700 VA / 420 W single-phase off-line (VFD) UPS designed to keep routers, switches, access points, small servers, and office endpoints operational through brief outages and unstable mains conditions. Its VFD waveform output and integrated surge protection focus on basic power conditioning and controlled shutdown coverage where full online double-conversion is not required.

With a typical runtime of up to 20 minutes at 50% load, the 3S700D supports orderly workload preservation for branch and desk-side deployments, reducing the risk of data loss and configuration corruption. The 3S700D integrates a CEE 7/7 input, 4x CEE 7/7 protected outputs, and 2x USB Type-A charging ports to consolidate power and peripheral needs in compact tower/desktop footprints while keeping cabling predictable and serviceable.

Why Choose the 3S700D?

The 3S700D provides a practical density-to-protection ratio for edge closets and workgroup areas by combining battery backup and surge protection in a small, lightweight unit. The 3S700D is well suited to standardized rollouts where consistent power behavior, straightforward outlet mapping, and repeatable runtime expectations support scalable branch deployment and reliable day-2 operations.

Eaton designs the 3S700D to align with modern enterprise electrical and safety requirements, including CB, CE, CM, EAC, and relevant IEC standards for UPS and surge protective performance. This engineering approach prioritizes predictable protection characteristics, compliance readiness, and operational continuity for distributed IT environments.

Key Applications:

• Branch router and switch protection
• Wi-Fi access point continuity
• Small server and NAS graceful shutdown coverage
• PC and peripheral runtime bridging
• Single-phase surge protection for edge devices
