New slim-line, 1-U rack-mounting Motech DS 3620 and 3640 programmable DC sources, available from, Westek Electronics, are ideal for incorporating in ATE set-ups as well as for individual testing tasks.
3620 and 3640 programmable DC sources feature low ripple of 5 millivolts in a wide bandwidth from 20 Hz to 20 MHz, high power factor (to 0.99), a standard USB interface and optional GPIB and LAN interfaces.
Both power supplies have high output voltages of 36 V DC and output currents of 20 A max. (DS 3620) and 40 A max. (DS 3640).
3620 and 3640 programmable DC sources may be operated in parallel or in series. Programming accuracy for voltage is 0.05% + 10 mV, and for current, 0.05% + 10 mA.
External analogue programming is provided for by way of voltage (0-10 volts) and resistance (0-10kW). The Motech power supplies can be operated via a rotary as well as keypad controls, or remotely via SCPI protocol.
