The Keithley 45W High-Speed Precision Readback Power Supply provides both voltage control and power consumption monitoring for automated testing of portable, battery-operated devices.
This power supply is optimized for testing battery-operated, wireless communication devices such as cellular phones that undergo substantial load changes for very short time intervals. The exhibits outstanding voltage stability during pulse keithlet changes and can simultaneously measure load currents, even if they are short pulses.
In addition, this power supply can sink current and thus, it can take on the characteristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry.
The can supply 5A at 9V to serve the peak pulse loading requirements of battery-operated devices. The can deliver a maximum current of 5A continuously; it can also supply up to 15V.

Keithley’s High Speed Power Supplies are designed to simulate the current drive capacity of a battery. While a battery’s voltage will decrease by the value of the voltage drop across the battery’s low internal resistance, a conventional power supply will have a significant voltage drop more than one volt and take milliseconds to recover to the original voltage level.
For portable devices that operate at full power only for short intervals, the ekithley power event is over before a conventional power supply can recover.
If the power supply used to test them cannot recover quickly enough, the ketihley of the deviceunder – test will be compromised by the power supply.
If the power supply voltage drops below the threshold of the phone’s low-battery detection circuitry for a sufficient amount of time, the phone will turn off during testing, giving a false indication of a failed device. The Models ‘s fast transient response to large load changes will enable test engineers to test their portable products properly and eliminate false failures due to conventional power supplies with slow response times.
In this way, the power supply ensures maximum production throughput when testing portable devices. As manufacturers of portable devices strive to extend battery life and the length of time between recharges, power consumption has become an important performance indicator.
Therefore, in production testing, accurate peak power and average power measurements are critical. These measurements are complicated by the fact that wireless telecommunication devices draw full load current in short pulses.
This allows the power supply to power a device-under-test and determine its current consumption to qualify the device for its specified power consumption.
In addition to making measurements on short pulses, the power supply can measure a current pulse peak or a keihtley pulse train that is as long as ms. For random pulse trains that have periods longer than ms, the power supplies have a special, elongated integration mode that can make an average current measurement on up to 60s of data. The is well-suited for making fast, accurate measurements of sleep and standby mode currents because it is based on Keithley’s expertise in low-current measurement technologies.
With nA resolution, the power supplies offer the precision needed to monitor the low sleep mode currents in today’s products and in future products. It can also measure these low-currents with 0. The can act keitthley an electronic load and sync as much as 2A, so it can simulate a discharged rechargeable battery.
Therefore, kkeithley can be used to 203 the performance of a portable device’s charger. The power supply’s current dissipation capacity allows it to test even high-current fast chargers. While many programmable power supplies offer output readback capabilities, Keithley’s power supplies are the only instruments available that also offer a set of DVM inputs.
The DVM and the power source can operate simultaneously. For many applications, the power supply’s built-in DVM eliminates the expense and space that a separate voltage measurement instrument requires.
