KIKUSUI PWX Series Programmable DC Power Supply

The PWX series is equipped with LAN, USB, and RS232C interfaces as standard features. By using the feature of virtual multi-channel bus (VMCB)*1span>, it allows you to control remotely and monitoring for 1-to-N as well as N-to-M for large-scale networks. In particular, the LAN interface is LXI compliant, enabling you to easily control and monitor the power supply through a browser on a PC, smart-phone, or tablet by accessing the web server built into the PWX series. Additionally, the optional application software, Wavy for PWX (SD013-PWX), sequence creation and control sof tware, allows you to change settings for specific channels (in individual) on VMCB-connected PWX series power supplies, and lets you perform batch control using global commands*2. You can also turn the output ON and OFF on multiple units and adjust the output voltage and current.

*1: This function for the PWX750ML applies to the firmware version 2.0 and later.
*2: This is only enabled for “Direct control” on Wavy for PWX. Global commands that can be also used under control with VXI-11, HiSLIP, and SCPI-RAW.

Basic configuration with LAN interface and VMCB (example)

As shown in the figure below, it is possible to connect a PC and the PWX series with a hub to create a virtual group using a LAN connec-tion. A maximum of 255 virtual groups can be set, and the maximum number of units can be configured up to 31 units per group. A group can have a mixture of models.

LAN Interface

The LAN inter face can control the number of devices with high speed, and it’s theoretical controllable maximum number is to be calculated by approximately 4.2 billion. (The maximum transmission speed varies by the number of connected devices) In accordance with its applied standard, it is possible to combine the device that is to control or to be controlled, it is also the feature that can be used with various applications. Also, in computers installed with Apple Bonjour, it is possible to access with a host name instead of the IP address.

The PWX series can automatically identify the type of LAN cable whether straight or cross is connected and it connects using the appropriate method.

USB Interface

The USB interface has a feature of high versatility, and the ease of a setup. The automatic recognition by the plug and play releases a user from the complex setting operation under the digital control, and it can be suitable interface when control by 1:1. In accordance with the standard, the maximum number of the connected devices can be configured up to 127 units. Moreover, the USB interface of the PWX series complies to USB2.0, and it has realized transmission speed of a maximum of 12Mbps (es) (Full Speed).

RS232C Interface

The PWX series is also equipped with a RS232C connector. It can be used for communication with PCs and sequencers. Since the PWX series has a RJ45 connector, it is required for a separate D-sub 9P-RJ45 adapter cable (RD-8P/9P).
