5 the evolion is a single 48 v module. The main components include a 14 cell pack of vl80e and two main electronic printed circuit boards. A battery management system telecom (bmst) is built into each module. With its microprocessor combined with the bmst software (or firmware), the bmst optimizes t...

12 4.5 internal heater the evolion uses an internal heater to optimize its performance. The internal heater operates as a function of the measured module temperature. It works in all modes of operation except sleep and safe modes. The load to the heater is supplied from the 48 vdc circuit. Approxima...

15 the evolion is designed to provide low power to the application for autonomies ranging from 2 hours and 5 days. When providing this duty, the voltage of the evolion operates with the typical voltage range of a 48 v nominal telecom bus. 5.1 normal operating voltage limits the evolion operates in a...

16 the module ocv can be measured at the terminals, by turning the unit on. While under load, an approximation of the ocv can be measured if the current, either charge or discharge, is less than 4.9 amps (at 25 ºc and higher). The internal resistance of the evolion module varies with temperature and...

19 when the network voltage is higher than the evolion terminal voltage, the module begins charging. The evolion re-charges with a typical constant current/constant voltage (cc/cv) profile. The maximum and recommended re-charge set point is 56.0 vdc +/- 0.5%. The temperature compensated voltage cont...

22 when integrating the evolion in the application make sure to avoid obstructing all of the vent ports. It is recommended to discuss venting strategy with your saft representative in order to conclude on the need to implement venting channels and suppression systems. See more details in the chapter...

26 the evolion communicates both a dry contact signal (alarming) and on an rs485/modbus network as a slave. For alarming, each evolion module measures and controls its own alarm output signal. The alarm output signal is given both by the led’s and the rj45 connectors on the front face. A complete li...
