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 new 2306-LAN Dual-Channel Battery Charger / Simulator provides a LAN communication interface through the added RJ-45 connector on the rear of the instrument.

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 readback. |
