The 1606-XLS120E power supply is an Allen-Bradley switched-mode power supply that is classified under the 1606 XLS series. The 1606-XLS120E power supply comes with a superior power reserve with the ability to support 150% of the rated power value for up to 5 seconds. With an ultra-small size, the 1606-XLS120E power supply is designed to provide a superior level of efficiency and it has a DC-OK signal with overload LED indicator for easy performance monitoring. The 1606-XLS120E power supply is a high-performance type of 1606 XLS power supply and it comes with a built-in large output capacitor. The 1606-XLS120E power supply comes with the ability to help start motors, charge capacitors and absorb the reverse energy while allowing a unit with a lower wattage class to be easily used with it.

The 1606-XLS120E power supply is designed to have a high level of immunity to transients and power surges and to have low electromagnetic emissions, making the unit suitable for use in nearly every industrial environment. The 1606-XLS120E power supply features a unique quick connect spring clamp terminal that allows for a safe and fast installation process. After the first switch-on, the charging current into the EMI suppression capacitors is disregarded within the first few milliseconds. The unit has been designed to support loads that come with higher short-term power requirements without causing the power supply to be damaged or to be powered down. The DC-OK relay contact allows for the monitoring of the output voltage that is produced by the power supply. The DC-OK signal is independent of the back-fed voltage from the unit that is connected in parallel to the power supply output.
