The maintenance-free module is suitable for short interruptions in the range of several 100 milliseconds, and combined with a battery module, bridges longer mains power failures, providing 40A for 30 minutes or 1A for 30 hours, depending on the requirement.
A range of battery modules is available with capacities from 3.4 to 17Ah. The DC-UPS monitors battery temperature and automatically moderates the charging voltage accordingly. to the temperature compensated charging recognition, which maximises the battery lifetime. Other features protect against over-discharge and deep-discharge, reverse polarity and power overload.
