Hybrid Power Management System Delivers AC/DC Output Using Any Battery Chemistry
Powerful HES 451 System's 25 Amps of Charging Power Optimizes Battery Life and Maximizes Run Times
Stamford, Conn. -- To make mobile medical carts more powerful and user-friendly, Hoffman Engineered Systems (HES) has introduced the 451 Hybrid Power Management System. This IEC 60601-1 3rd Edition-compliant, patent-pending power management system accepts any battery technology and converts the battery's DC power into AC and DC outputs, allowing the system to efficiently operate electronic devices without converters, inverters or adapters. To accelerate battery charging, the 451 system provides 450 watts of power to rapidly charge any size battery with 25 amps of output, optimizing run times and extending battery life.
Lightweight and compact, the HES 451 Hybrid Power Management System delivers more mobility for healthcare electronics, providing a minimum 12-hour run time while protecting critical data and ensuring optimum battery life and user safety. The system accepts worldwide universal input power and provides simultaneous 5, 12 and 19.5 VDC outputs along with a 120 VAC True Sine wave output. The True Sine wave constructed output provides a perfect sine wave for protection of sensitive computer electronics. The 25 amp charging capability is highly effective on batteries larger than 40 Ah, and provides up to 25% more run time per minute of charge time.
The HES 451 Hybrid Power Management System is available for manufacturers of mobile medical carts and as a retrofit package for medical carts that are presently in operation. If AC output is not required, the 451 is also available as a DC-only system.
The 451 Hybrid Power Management System features an intuitive display similar to an automotive fuel gauge that reports the state of the battery's charge. To ensure the safety of critical patient data, the system warns the user several times as the battery approaches full discharge, and then performs an orderly automatic shutdown that preserves information.
The system accepts all existing battery chemistries including lithium iron phosphate and sealed lead acid. To accommodate any future battery chemistries, HES provides a simple update to the charging tables in the system’s proprietary battery charging software.
Safety interlocks protect batteries from outgassing, overheating and failure, while specially designed circuitry isolates and protects both sensitive electronics and the user of the cart. The system provides a real-time estimate of the health of the battery and informs the user when the battery requires maintenance or is nearing replacement. The system's charging efficiency extends battery life and minimizes the frequency of battery replacement, reducing replacement and recycling costs.
Measuring just 3.5-inches high by 6.0-inches wide by 10.25-inches long and weighing less than 6 pounds without batteries, the 451 System fits easily onto most medical mobile carts and accepts many battery post configurations.
