Military Grade Expansion Battery Pack | -40 °C to +55 °C Operating Temperature
The BAT-0400-H-1U Series is a military-grade expansion battery pack that uses lithium polymer batteries and highly efficient power electronic circuitry to achieve a high power level and battery run-time in a low-profile, low-weight, rack-mountable package. It is designed specifically for use with SynQor UPS-1250, UPS-1500 and UPS-3000 series uninterruptible power supplies (UPS). It is designed for the extreme environmental and demanding electrical conditions of Military/Aerospace applications.
The pack cannot be used as a standalone battery. Multiple layers of circuit protection are implemented internal to the battery pack. Features include heater resistors for operating down to -40°C ambient, and internal hardware protection and status monitoring.
The BAT-0400-M pack provides cold-start operation down to -40°C. A cold-start is an enable of the UPS using only battery power, with no input power available. Below -20°C, following a cold-start enable command from the user, the BAT-0400 will pre-heat itself to operational temperature, then enable the UPS output.
From a start with the battery pack soaked at -40°C, the cold-start pre-heat takes 3.5 minutes. The pre-heat terminates based on internal cell temperatures, so a cold-start from a temperature warmer than -40°C will take less than 3.5 minutes. Although operation at full output load requires a full pre-heat sequence, the user can optionally set the pre-heat to terminate early if the output load is known to be less than full load.
