Tripp Lite BC350R 350VA 210W 120V UPS

Desktop Standby UPS

The Tripp Lite BC350R is a 350VA standby uninterruptible power supply rated at 210W for 120V environments. It provides battery backup and surge protection for a desktop PC, networking gear or a workstation. The unit mounts on a desktop, a surface or a wall using the included M4 screws. It is suited to users who need basic power continuity during brief outages.

Replaces Basic Surge Strip

This UPS replaces a standard surge-protected power strip by adding battery runtime when utility power fails. The jump is worth it when a short outage would lose unsaved work, drop a network connection or corrupt a local database. It supplies three NEMA 5-15R outlets that deliver both surge protection and battery backup. Buyers who need extended runtime for servers or multiple monitors should look elsewhere.

Behaviour Under Sustained Load

In standby topology the inverter engages only after a power loss, so the transfer time is a few milliseconds. The 210W capacity supports a typical desktop and router for a few minutes, allowing an orderly shutdown. Battery voltage drops steadily during discharge; the unit signals low-battery and fault conditions through front-panel LEDs. It is not designed for continuous full-load operation or for equipment with active power-factor-corrected supplies that require pure sine-wave output.
