Universal Power Bridge

The Universal Power Bridge protects devices such as a data logger against voltage fluctuations and power failures.

Product
Overview

The UPoB is a universal power bridge that protects the connected system, such as a data logger, against voltage fluctuations and power failures. The device is able to override the fluctuations for their duration of time. In case of a complete power failure, a minimal voltage level is maintained until the connected system is shut down safely.

Four standard options of the UPoB are available that vary in the total capacitance of the built-in capacitors (12.5 F, 25 F, 50 F or 75 F) and therefore in the maximum bridging time. Other configurations are also possible.

The UPoB optionally sends a trigger signal via communication interface when a certain configurable threshold of the charging percentage is reached. The communication interface consists of RS232 interface, CAN interface, digital switching output and relay output. Status messages are sent via CAN bus to be analysed by a data logger. The user can also set the desired charge current.
