UPS module now optionally available for our electric ARI-PREMIO® Plus 2G actuators. Even more safety made by ARI®.
The new UPS module (uninterruptible power supply) is now available for the ARI-PREMIO® Plus 2G electric actuator. The UPS module can be added or retrofitted to all actuator sizes. The nickel metal hydride battery (NiMH) ensures a 30-minute power supply to the actuator after a power failure. The LED light on the UPS module makes it easy to read the current status of the module. With the new solution from ARI®, any actuator can be supplied with one UPS module!
The most important information about our new UPS module in brief:
- The UPS module can be retrofitted
- The emergency position can be set via a switch (open / follow control signal / closed)
- The battery is a nickel-metal hydride (NiMH) battery
- One UPS module for all actuator sizes (for all actuating forces from 2.2 kN to 25 kN)
- The temperature range of the battery pack is from –20 °C to 70 °C
- The NiMH battery provides significantly more energy than supercapacitors (approx. factor 8 to 10)
- The current status of the module can be read out via potential-free contacts
- An LED on the front of the UPS module provides information about the current status of the module
