The 1609-D1000N uninterruptible power supply unit comes from the 1609-D series by Allen-Bradley/Rockwell Automation and it serves as a reliable backup power source for a variety of industrial systems. The unit weighs nearly 30 pounds (13.5 kilograms) and it has the following dimensions (L x W x H): 220 x 410 x 260 millimeters (8.66 x 16.14 x 10.24 inches). The 1609-D1000N power supply unit is a 120 Volts AC unit with an input/output capacity of 1000 Volt-Amps (650 Watts) and a default voltage range of 90 to 145 Volts AC. The default voltage range of the unit is also its widest online voltage range, while its nominal current rating is 8.8 Amps. The frequency capacity of the unit is 50 to 60 Hertz. The output voltage range is 108 to 132 Volts AC and the online transfer point accuracy is ±3%. The total harmonic distortion (THD) value for this model is less than or equal to 10% in the case of a full linear load. 

The 1609-D1000N uninterruptible power supply unit runs on an internal replaceable battery that has a run time of up to 3.5 minutes when at full load and 25 degrees Celsius of operating temperature. The type of the battery that is used is a lead-acid (sealed) battery with a 12 Volts or 5 milliAmps per hour capacity. The voltage of the battery is 36 Volts while the time it needs to recharge is less than 8 hours. The typical lifespan of the battery is 2 to 3 years at an ambient operating temperature of 25 degrees Celsius. The short circuit protection of the 1609-D1000N power supply unit comes with a crest factor of 2.2:1 and it also includes 380 joules of surge protection. In addition to that, the unit has the capability to provide protection from current overload when it exceeds 110% of the normal rating, with options for immediate shutdown or shutdown after 10 seconds. Also, the 1609-D1000N power supply unit provides excellent thermal protection, allowing for an internal operating temperature of up to 60 degrees Celsius. This power supply unit meets the UL, FCC, cULus, CE, and C-Tick standards. It complies with safety standards such as the UL1778, EN/IEC62040-1, and CSA C22.2 (No. 107.3).
