STEP-UPS/12DC/12DC/4/46WH - Uninterruptible power supply

1082548

Uninterruptible power supply with integrated battery. The STEP-BAT/LI-ION/18.5DC/46WH battery can be re-ordered separately.

UPS modules with integrated battery are particularly space-saving: the UPS module and battery are combined in one housing. It’s just a case of connecting a power supply upstream.

General
Note on the battery This product contains a battery with a limited shelf life that must be charged every few months. The product packaging indicates when the battery must be started up or recharged. The general shelf life can be found in the technical data area under “Latest startup”.
