Keysight E3648A Power Supply
The Keysight E3648A power supply is a dual output programmable DC unit that support GPIB interface communication. It provides two isolated outputs with flexible voltage ranges where each output operates from 0 V to 8 V at 5 A and also supports operation from 0 V to 20 V at 2.5 A per channel. The unit consumes 100 W power for various high energy requirement domains. The unit operates within a nominal operating temperature range that lies between 0 °C to 40 °C. The E3648A delivers precise load and line regulation across its full output ratings with voltage accuracy better than 0.01% +3 mV. The accuracy of the current regulation is maintained below 0.01% +250 μA.
The Keysight power supply minimizes ripple and noise over a bandwidth of 20 Hz to 20 MHz with normal mode voltage ripple below 5 mVpp. The voltage software design accuracy is less than 0.05% plus 10 mV while Output 2 program design voltage accuracy is less than 0.1% +25 mV. The power supply uses front panel meter accuracy that corresponds directly to actual output values with voltage meter accuracy less than 0.05%. The unit provides fast transient response with recovery time less than 50 μsec for a 15 mV. This deviation occurs during load changes from full load to half load and maintains common mode current below 1.5 μArms.
The voltage programming resolution is 5 mV and current programming resolution is 1 mA while the unit contains voltage resolution of 2 mV. The Readback accuracy across the GPIB interface indicates the actual output values and meter accuracy of less than 0.15% plus 10 mV. The current read-back perseverance of the unit is 1 mA and meter resolution is 10 mV when voltage and current are read. The E3648A uses an output stabilization settling time that is found to be less than 90 msec. It also allows remote control and monitoring via the GPIB interface and includes an EU power cord arrangement. This power supply offers independent isolated channels in use in laboratory and production test applications that need controlled and accurate DC output.
