SPECIFICATIONS
The LPS 305 power supply's smart microprocessor technology & features make it very easy to use. The settings are kept in a memory, so when turned on, the voltage, current and output options are just as they were when you turned it off. The LPS305 is software calibrated to provide years of trouble free service and for instrument & load protection, has audible feedback to warn if output exceeds maximum load.
Use the keypad to easily select exact
voltage and current settings.
The intelligent cooling system turns on automatically when the power rating exceeds a preset value.
The clear LCD simultaneously displays positive & negative voltages and currents, along with the constant voltage/constant current status of each. The output mode (independent or tracking) & the fixed output (5V or 3.3V) are indicated on the right hand side.
