Protect B Pro


With its increased power factor of 0.9lag the Protect B PRO belongs to the most efficient line-interactive UPS systems. The parallel operation of USB/RS232 interface and the extension slot enables more communication options. Protect B Pro can be configured via the operator panel. The innovative folding mechanism allows batteries to be changed without disconnecting the UPS.


Higher efficiency

The Protect B. PRO achieves more than 30% higher power in comparison to conventional uninterruptible power systems, due to it‘s new power factor rating of 0.9 lagging across it‘s operating range. 


The display shows several parameters: input, UPS mode and output. Three LEDs at the top of the display indicate the current operating mode. From the control panel the user is able to configure the UPS settings and activate an audible alarm.

Battery management
The battery management system is able to differentiate between initialization during setup, the battery charging phase (temperature compensated) and the standby phase. This enables the system to extend battery lifetime as there is a decrease of pole corrosion.


Communications options
Communication options are provided by several interfaces including programmable potential-free contacts, emergency power off switch, RS232, USB and an extension slot that can be used in parallel mode.
