DC-To-AC Inverter Carries Hot-Swap Capability

Based on pulse width modulation technology, Topaz S3 2-kVA inverter is targeted for use in telecomm, networking and other applications requiring reliable, uninterrupted ac power from a dc source. In addition to producing distortion-free ac sinewave power, the dc-to-ac, microprocessor-controlled unit employs a standard hot-swap inverter that can be easily removed without interrupting the load. Other features claimed for Topaz S3 include excellent overload capability, field-selectable voltages and frequency, and a Static Transfer Switch that enables the inverter to operate in either an on-line or standby mode to save energy. The inverter's overload rating is up to 125% continuous, and overloads of 220% to 300% can be accommodated for up to four cycles. Input voltage is ±48V nominal with a 60V option and output is rated at 100V, 110V, 115V, 120V, 200V, 220V or 240V (field selectable) with an output frequency of 50 or 60 Hz (field selectable).
