Industrial-Grade UPS Targets Global Applications

A series of industrial-grade buffer and dc uninterruptible power supplies produce reliable 24-V supplies as commonly required in many factory applications throughout the world. The Quint Buffer and Quint DC-UPS from Phoenix Contact ensure continuous operation of all 24-V equipment during power interruptions lasting anywhere from a few seconds to several hours.

These supplies prevent unstable power grids from causing failures in international applications. A buffer module and three UPS modules provide the appropriate response to varying demands on output current and buffer time. For power interruptions lasting up to 4 sec, the Quint Buffer module delivers the required current from maintenance-free electrolytic capacitators. This approach handles brief power outages with minimal expense. The Quint DC-UPS module responds to longer outages with durable, hybrid, lead-acid storage batteries. The hybrid-style battery provides longer life expectancy and less maintenance than standard lead-acid batteries.

One version of the DC-UPS module offers a 10-A output and includes an integrated 1.3-Ah battery. There are also 20-A and 40-A models, which can be combined with 3.4-Ah, 7.2-Ah and 12-Ah battery modules as desired. Dividing smaller batteries into ‘buffered’ and ‘unbuffered’ loads can save money and take up less space in the control cabinet.
