Outline
The PWX series is a CVCC programmable regulated DC power supply designed to optimize for a rack-mounted power supply. To increase its mounting efficiency, it has a 19-inch rack width with a thin shape and intakes and outtakes for cooling on only the front and back surfaces so that it can be mounted flush top and bottom. The series is equipped standard with USB, RS-232C, and LAN interfaces, which are essential for system upgrades. The series also has a virtual multi-channel bus (VMCB) function that allows it to be used efficiently for remote control and monitoring with 1-to-N and as well as with N-to-M in large-scale networks. In particular, the LAN interface is LXI compliant*, enabling you to control and monitor the power supply easily from a browser on a PC, smartphone, or tablet. You can also manage the power supply in a different building.
Two output power specifications are available: 750 W and 1500 W, and a wide range of voltage and current settings can be combined within its output power rating (3 times). For example, the output power of 1500 W model, the PWX1500ML is capable to operate seamlessly from the range of “80 V-18.75 A” to “26.8 V-56 A”. The input voltage has a universal 85 V to 265 V input voltage range, and the unit also has an internal power factor correction (PFC) circuit to control the harmonic current. It also includes an analog external control/monitoring output, master-slave parallel operation function, various protective functions, and memory function.

 The PWX series is equipped with LAN, USB, and RS232C interfaces as standard features. By using the feature of virtual multi-channel bus (VMCB), 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*1 , enabling you to easily control and monitor the power supply through a browser on a PC, smartphone, 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 software, 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 connection. 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.
- Easy access with the built-in web server
 Use a browser from a PC, smartphone, or tablet to access the web server built into the PWX series for convenient control and monitoring.
- Operating Range: 3 times output power rating
 A wide range of voltage and current settings can be combined within its output power rating (3 times).For example, the output power of 1500 W model, the PWX1500ML is capable to operate seamlessly from the range of "80 V-18.75 A" to "26.8 V-56 A".
- Application Software
Sequence Creation Software SD013-PWX (Wavy for PWX)
 The software that supports to the auto testing of the power supply.Allows you to create and edit sequence data easily using a mouse !
SD013-PWX (Wavy for PWX) is an application software that supports sequence creation and the operation for Kikusui power supplies and electronic loads. Wavy allows you to create and edit sequences visually with a mouse without programming knowledge. It enables you to control the power supply in much the same way as remote controller for such monitoring the voltage and current, logging and so on.
- Variable Internal Resistance Feature
 The variable internal resistance feature enables you to easily simulate the internal resistance of rechargeable batteries, solar batteries, fuel cells, and the like. By setting the internal resistance value in constant voltage(CV) mode, you can decrease the output voltage according to the output current. You can use a CONFIG setting or interface(LAN/USB/RS232C) to set the internal resistance.
