Phoenix Contact has released a compact uninterruptible power supply with an integrated battery. Called the STEP UPS, it provides standby power for short-term power losses in low-current applications.
It has a three-amp output current, and corresponds with the STEP power supply with 4.2 A nominal current. The narrow UPS (108mm) requires minimal space on the DIN rail.
It comes in both 24 V DC and 12 V DC versions with an integrated lithium-polymer rechargeable battery.
The 24 V version has an input range of 22.5 to 29.5 V DC, while the 12 V version operates between 10 and 16.5 V DC.
The amount of back-up time available depends on load currents connected to the buffer module, but can range between 12 and 53 minutes.
The modules contain status LEDs indicating the unit’s operational condition; the status of which can be communicated to a supervisory control system via the integrated status contacts. The battery runtime can be adjusted via a rotary dial to prevent over discharge.
