Testing portable, battery-operated devices under real-word conditions demands a DC power supply that can simulate a battery’s performance over a wide range of conditions. Series 2300 battery simulating power supplies can simulate both a battery's output resistance and output voltage response. The dual-channel versions of these power supplies provide one channel to act like a battery and sink current for simulating a discharged rechargeable battery; the other channel supplies voltage for testing a device’s charge control circuitry.
The single-channel Model 2302 Battery Simulator and dual-channel Model 2306 Battery/ Charger Simulator were designed specifically for development and test applications of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers.
These precision power supplies have ultrafast transient response so they can have output characteristics identical to actual batteries. These supplies employ a unique variable output resistance so the voltage output can emulate a battery’s response (U.S. Patent No. 6,204,647).
They provide stable voltage outputs, even when a device-under-test (DUT) makes the rapid transition from the standby (low current) state to the RF transmission (high current) state. In addition, they can monitor DUT power consumption by measuring both DC currents and pulse load currents. The Model 2302’s and the Model 2306’s battery-simulator channel can be programmed to operate like a discharged rechargeable battery, sinking current from a separate charger or from the Model 2306’s charger-simulator channel.

Key Features | Benefits |
Ultra-fast response to transient load currents | Provides output characteristics identical to actual batteries. |
Variable output resistance | Allows simulating a battery’s internal resistance. |
Pulse peak, average, and baseline load current measurements | Supports measuring load currents for power consumption verification or analysis. |
100nA DC current sensitivity | Provides the sensitivity needed to monitor the low sleep mode currents of battery-operated products. |
Current step measure function | Supports measuring the load current at each level of a device’s operational states. |
Sink up to 3A | Acts just like an electronic load, which allows these supplies to simulate a discharged rechargeable battery for use in testing the performance of battery chargers or battery charger control circuitry. |
Open sense lead detection | Indicates if there is a broken remote sense lead or an open connection from a remote sense lead to the test fixture. |
Built-in digital voltmeter | Allows measuring signals from –5V to +30V DC anywhere in the test system with the same rated accuracy as the supply’s voltage |
