These programmable switching DC power supplies feature new switching technologies to offer more power at a lower cost than traditional linear power supplies. Units are ideal for repetitive test routines in R&D, production, product evaluation applications and more. The built-in micro-controller unit along with the included software lets you perform recalibration without opening the case. Use the built-in RS-232 interface to remotely control the power supply or program a sequence of different voltages and current limits that can be used in an automated test application. Units feature data logging with color graphic display in adjusting voltage range, current, watts, and time periods, providing valuable data analysis tools.
