Product Review of the CSI3644A/45A/46A Programmable DC Power Supplies

Circuit Specialists offers several Programmable DC Power Supplies that vary in price range and available features. These power supplies may be run manually as standard bench top power supplies or may be controlled and monitored by an external computer system. The CSI3600 series of programmable power supplies are feature rich single output power supplies that may be run in constant voltage, constant current, or constant power mode.

Each unit features completely isolated outputs which may be connected in series or parallel configurations for higher current and voltage operation. The CSI3644 is capable of operation from 0-18 volts with up to 5 Amps output current. The CSI3645 is capable of operation from 0-36 volts with up to 3 Amps output current. The CSI3646 is capable of operation from 0-72 volts with up to 1.5 Amps output current. Other than the maximum output voltage and current ratings, the three models are identical in operation and feature set. They offer programmable or adjustable current limiting and constant current operation with resolution as fine as 1mV for voltage and 1mA for current. These parameters may be set via numeric keypad entry or by using the rotary knob for continuous variation. The desired voltage and current levels may be stored in the units on-board, non-volatile memory, for easy retrieval of commonly used settings. Ten sets of voltage and current values may be saved if desired.

All three models are supplied with the necessary drivers and computer control/monitoring software for Windows compatible computers. An optional converter is required for connections to USB, RS-232, or RS-485 networks. The software offers real-time monitoring and control of all operations using an easy to use GUI. The Circuit Specialists CSI3600 series of Programmable DC Power supplies are powerful, low cost Power supplies with features that rival more expensive units. They are well suited for use in design and development labs, test and repair facilities, and manufacturing environments.
