The "Brownout and Load Dump module" (BOLD-1) protects the PIP in case of sudden input voltage changes, as well as by unexpected interrupts. The module keeps the PIP or Panel-PC system operational and prevents data loss or damage even if the input power is not stable.
A Brownout is if the input voltage level goes unexpected below the minimum level specified for the system. A Dropout specifies the unexpected loss of input power for milliseconds to seconds or minutes.
The BOLD module prevents that the system in case of a brownout or dropout event is not immediately and unregulated switched off. Instead, the input power supply is immediately switched to an additional battery to carry on the normal operation. In case the regular input power does not recover within a useful time, the module will do a controlled shut down of the computer via the standard serial UPS signals.
A Load dump occurs mostly in vehicles and refers to what happens to the supply voltage when a load is removed. If a load is removed rapidly, it can generate over voltage peaks which apply for a few ms before the voltage is stabilized again. The BOLD module protects the system from such peaks. The maximum allowable transient can reach up to 80 V.
In addition to the above function, the BOLD module also offers Reverse Input Voltage Protection up to -60 V. Further a charger (designed for Lithium Polymer batteries) is present to recharge the battery. The LiPo battery can be used in a wide temperature range from -20...+60°C.
