]]>The heavy-duty chassis, occupying only 3U (5.25″ high) of rack space and 18.5″ depth, has rounded metal corners and rugged handles front and rear, aiding in safe handling. The companion 2U(3.5″ high) Battery Expansion Modules are designed to be daisy chained to bring the backup time to 4 hours in the typical configuration. In the typical ECMO Cart application, the base UPS unit and up to four Battery Modules are mounted in the lower underside section of the patient cart. Both module chassis are constructed of brushed aluminum to minimize overall weight. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration.
The internal shielded input transformer provides galvanic isolation with provisions for domestic (115 VAC, CONUS) and optionally for international (230 VAC, OCONUS) input voltages. Special EMI/RFI filters and input power factor correction minimize both input current and harmonics. This special transformer and filters result in ultra low input leakage current required for medical applications. The unit also operates as a frequency converter, taking 46-440 hertz input and converting it to clean, uninterruptible 60 hertz power. The input switch and the galvanic isolation transformer all provide a double pole isolated source for systems or locations where phase references and grounding are not consistent. For scenarios that need hospital grade power immediately and no AC source is available to run the UPS, the Cold Start push button allows the unit to start and run from its battery modules before external AC is available.
The LED arrays keep the operator informed as to the unit’s status including load and battery levels. The high intensity audible alarm can be heard in high noise environments. All controls and protective devices are brought to the front and rear panels with critical switches having finger guards. Further, all front panel devices are recessed to prevent damage or accidental operation. Various optional power distribution controls are available which mount on the front panel or remotely.
The rear panel provides a locking connector for the input power and six hospital grade NEMA 5-15R output receptacles. Multiple input and output power panel options are available. Removable and washable air filters and a high capacity stainless steel ball bearing fans provide added protection in both controlled and hostile environments. The exhaust air is diverted out the front vent, with alternate air flow directions optional. The “ETI0001-1240” has the added benefit of having both an internal battery and external battery expansion modules. The external Battery Modules can be field replaced without having to shut the UPS down. This allows the backup time to be extended even further. The optional Battery Charger/Conditioner (which has aircraft and global input capability) is used to maintain the spare Battery Modules in ready condition at all times. The batteries are maintenance free with immobilized electrolyte and are constructed of flame retardant materials. For more information, see the Battery Technology section. The Status connector provides an interface with optional computer software providing loss of AC and low battery status as well as remote shut down capability.
