The 41-750 is a battery simulator module that can be used to simulate the power supplies of cellular phones and other portable battery devices. It features fully floating output terminals than can deliver voltages up to 6 Volts. The fast responding remote sense connections allow the module to regulate the supply voltage at the device under test. The output terminals can float ±50V relative to the front panel ground to ensure the accurate simulation of battery operation.

A module can source or sink current to provide simulation of a battery supply or a battery under charge. The use of two modules allows the simulation of both the charger voltage source and the battery. The programmable current sink can be set to divert up to 0.5A of the load current, permitting the battery simulator to act as a net current sink when connected to a charger circuit. The 41-750 is capable of delivering up to 2.8 Amps into the load.

The module derives its power from the PXI backplane and requires no external power source.

The battery simulator can be configured to prevent misleading operation. If the remote sense lines are not connected to the device under test, the power supply is automatically shut down. The alternative configuration regulates the front panel voltage if the sense lines are not connected to the load.

Monitoring of the output voltage and current is provided through the simple to connect Pickering Interfaces Monitor facility. A single DMM can be used to report voltages and currents on multiple modules, through an easily implemented daisy chain connection. This facility can also be used to monitor other types of modules in the Pickering range. The wide bandwidth of the monitor facility allows the use of external data acquisition devices to capture voltage and current variations with time.
