TDK-Lambda's Z+ Series programmable DC power supplies are available in 200, 400, 600, and 800 W. The Z+ programmable power supply has comprehensive front panel controls with individual rotary encoders for output current and voltage, and access to power supply settings such as OVP level, start-up modes, remote control, and monitoring parameters. Separate 4-digit volt and current displays are provided along with function/status LEDs, pushbuttons for output preview, output on/off, fine/coarse, and other features.
Common to all Z+ models are the built-in USB, RS232, and RS485 interfaces. Using the standard serial RS485 interface between units enables daisy chain control of up to 31 power supplies on the same bus. Analog remote programming and monitoring is user selectable from 0-5 V or 0-10 V. Other digital and isolated analog interfaces are optional. The GPIB interface is IEEE-488.2 SCPI compliant and multi-drop (only one unit needs the IEEE interface, which can then feed the commands to others via RS485). LabView® and LabWindows® drivers are also available. Isolated analog programming and monitoring options include either 0-5 V or 0-10 V, and 4-20 mA control. An LXI Class C compliant LAN interface is also available.
