Integrated UPS
ASEM has developed for its IPCs an integrated UPS (Uninterruptable Power Supply) system to prevent sudden shutdowns, resulting in data loss or damage due to an unexpected lack of primary power supply.
To ensure maximum reliability and noise immunity, the control electronics are integrated into the power supply module, so that the communication interfaces between IPC and UPS are kept inside the system.
The control logic, organized on several levels, is completely designed and developed by ASEM R&D team and includes
- a hardware section capable of switching in negligible time (in the order of microseconds) the power source of the primary voltage to the battery and vice versa;
- a configurable hardware section to monitor the battery status and manage the charge and discharge phases;
- a microcontroller-based control section that manages the system states and interfaces with the IPC;
- a high level software section, in Windows environment, configurable by the user, which performs the diagnosis of the system and battery pack status and manages the shutdown.
The architecture is common to all systems and is customized by configuring some specific parameters based on the type of use and consumption to optimize battery life.
Software
The operation of the systems with UPS is managed by a high level software, developed for Windows environment, divided into two parts:
- a service in charge of monitoring the status of the supply voltage and the battery and managing a possible shutdown;
- a graphic application that can be used to configure the behavior in case of primary voltage failure and to check the diagnostics.
Moreover, in order to preserve the battery from an anomalous degradation and to avoid sudden shutdowns, if a voltage lower than the expected minimum is measured, a regular system shutdown is commanded independently from the set parameters.
HIGHLIGHTS
Battery packs
Lead Acid Batteries (Pb)
The battery packs with lead acid cells, compared to the most modern technologies, have important dimensions and encumbrances, but they are able to provide high peak currents and can operate in a wide temperature range (well beyond the 0 - 50°C guaranteed for the systems).
They consist of 6 elements for a nominal voltage of 12V and can deliver a maximum of 100W for about 2 minutes, they also integrate a temperature sensor and a protection circuit that breaks the connection in case the current is too high or the voltage too low.
Nickel-Metal-Hydride (Ni-MH) Batteries
Battery packs with Ni-MH cells are characterized by smaller size compared to lead-acid ones and less self-discharge during storage.
They consist of 10 cells for a nominal voltage of 12V and can deliver a maximum of 60W for about 10 minutes. They also integrate a temperature sensor, a protection circuit that breaks the connection in case the current is too high or the voltage too low and a switch to disconnect the battery during transport.
