A modern fighting vehicle is completely dependent on its electrical system for mission success. The use of an Intelligent Power Control System (IPCS) guarantees that a 'whole vehicle' approach is used for the design of the system, ensuring that it can cope with the complex demands of a modern vehicle.
The IPCS uses a MilCAN compliant data bus and solid state switching technology to implement a system that reduces vehicle wiring, connectors, fuses/circuit breakers and electromechanical relays. Intelligence embodied into the system enhances overall system capability and improves diagnostics. An IPCS in a fighting vehicle does not only replace a conventional system, but also offers opportunities to improve the vehicle performance and reduce the crew workload.

Intelligent system control is one of the key benefits of the IPCS approach to power management. It is provided by a dual redundant pair of Bus Controller Modules. These modules also contain the power management system interfaces to the vehicle command and control data bus.
Operation of a modern fighting vehicle is no longer a simple case of switching a piece of equipment on and off when required. Interlocking and sequential operations are often essential. In the event of a fault or failure, reconfiguration of the system may be essential to maintain serviceability.
This automation can be a very simple sequence such as may be required to ensure a safe vehicle power down, or a complex sequence of operations dependent on other inputs. Load shedding functions can be incorporated, and tailored to the operational mode of the vehicle. 'Limp home' options can also be included that would, for example revert control of an equipment to a manual switch if data bus control was not available or automatically select alternative loads in the event of equipment failure.
Each bus controller provides a dual MilCAN interface to the vehicle bus and translate high level commands, e.g. Go to Blackout, into the necessary instructions to the individual loads affected.
By placing the low level power management functions in a dedicated controller, the vehicle computer work load is reduced as is traffic on the vehicle databus network. Changes to the vehicle electrical system requirements are more readily implemented.
Features
- Designed to operate as an active and standby pair with automatic switch-over.
- Downloadable software.
- System configuration (load output rating, monitoring options, etc.) downloadable. New equipment/vehicle role change easily accommodated.
- Automates routine functions, e.g. vehicle master power up.
- Provides Power System diagnostic information, including information on intermittent faults.

|
The Remote Terminals provide the interface between the vehicle electrical loads. The remote terminals are located in geographically convenient locations (to minimise cable length) within the vehicle and can control up to 16 loads and/or interface to 16 input switches. The remote terminal provide a high degree of user configuration, including trip current setting, automatic retry of tripped loads, hi or low side sense programming of individual inputs, and default states for each output should data buses be lost.
On Off control, status monitoring, output reset and diagnostic data are all available via the data bus network and hence require no user interface at the terminal. Remote terminals are equipped with databus readable Elapsed Time Indicators to assist with vehicle health and usage monitoring requirements
Features
- 16 Outputs - Solid state switching elements
- Standard design - only programming changes from vehicle to vehicle
- Programmable trip point on all outputs
- On/Off/trip status reporting
- Open circuit detection
- Definable default states if data bus lost
- 16 inputs - whetting current provided
- Inputs individually Hi/Lo side programmable
- Dual redundant MilCAN databus
- Bus readable Elapsed Time Indicator

The Distribution Unit interfaces to the vehicle power sources - e.g. vehicle batteries and generator - and distributes the power to the PMS remote terminals via intermediate power bus bars. On request the PMS provides sequenced power up/down of vehicle resources.
The Distribution Unit can also provide controlled outputs to specific high power loads via Smart Contactors. These are controlled and monitored by the PMS
A battery monitoring capability can also be included within the Distribution Unit to monitor the status of up to two battery packs.
Features
- Smart Contactors for bus bar protection & isolation
- Distribution system status monitoring
- On/Off/trip reporting for bus bars
- Direct control of local loads
- Direct control of high power loads (>50Amp)
- System inputs - whetting current provided
- Dual redundant MilCAN databus
- Bus readable Elapsed Time Indicator
- Battery monitoring of vehicle batteries
- Automated Power Up/Down sequencing
