TDI Debuts Battery Manager to Monitor Battery Back-Up Systems
A new battery manager from the telecommunications power system division of TDI Transistor Devices (Hackettstown, NJ) has been designed to be used with the TDI power plant. Together, the two devices monitor and report damage or hazardous operation of critical battery systems.
The battery manager reports the monitored data plus the need for service or repair via the power plant manager, which is equipped with an RS232 port, an internal modem and an Ethernet port. Incorporated in the battery manager is an internal 1,200A/1,800A low-voltage disconnect that provides for emergency power off.
The battery manager incorporates four temperature probes and four voltage monitors, located in each quarter of the battery string, to detect open cells, shorted cells and thermal runaway. Other features of the battery manager include high-float current alarm, three-form 1C contacts and an alpha-numeric display. When used in conjunction with the power plant manager, the battery manager provides periodic discharge testing to verify the integrity of the batteries.
