Medical-Grade UPS for Patient-Care Areas

The Tripp Lite OMNISMART350HG is a 330VA line-interactive UPS built with hospital-grade NEMA 5-15P input and four NEMA 5-15R-HG outlets. It carries UL 60601-1 listing for use with medical electrical equipment in patient-care areas. An isolation transformer with Faraday shield provides full isolation and removes common-mode noise.

Sustained Load Behaviour

Line-interactive regulation maintains a 120V sine-wave output across an input range of 83 to 132V, correcting brownouts without drawing on the battery. At full load the sealed VRLA battery delivers 18 minutes of runtime, extending to 46 minutes at half load. Recharge to 90 percent capacity takes 2 to 4 hours after a discharge event.

Decisive Specification

The four hospital-grade outlets and UL 60601-1 compliance determine whether this unit fits a clinical environment. Facilities that require standard NEMA outlets or lack medical-equipment certification needs should select a different model.

Questions about this item

How loud is the OMNISMART350HG when it runs on battery power all day?

An audible alarm sounds during power failure and can be silenced with the cancel switch; it resumes automatically when roughly two minutes of battery runtime remain at full load.

Which cable or plug must I already have to connect the OMNISMART350HG to the wall?

The unit ships with a hospital-grade NEMA 5-15P input plug for a standard 120 V 15 A receptacle.

Will the DB-9 port on the OMNISMART350HG work with my older server that only has a serial console?

The DB-9 communications port works with PowerAlert software and cabling for unattended shutdown of connected PCs and network gear.
