Features
The PWX series is a CV/CC programmable regulated DC power supply optimally designed for rack-mounted operation. 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.
Furthermore, this series is equipped with essential communication interfaces for system upgrades, including LAN, USB, and RS232C as standard. By utilizing the VMCB (Virtual Multichannel Bus) function*, efficient remote control and monitoring of 1-to-N, N-to-M, and large-scale network types can be achieved. LAN communication allows control and monitoring from web browsers on PCs, smartphones, and tablets. Additionally, it is certified for LXI (LAN eXtensions for Instrumentation), making it easy to configure when connecting to measurement systems via LAN. Remote management of power supplies located in separate buildings can also be easily realized.
The output specifications include two types of output power: 750W and 1500W, with a wide range of voltage and current settings possible in a “3:1” power type. For example, the PWX1500ML with a rated output power of 1500W allows seamless operation from 80V-18.75A to 26.8V-56A. The input power voltage is also a universal specification of 85V to 265V, with a built-in PFC (Power Factor Correction) circuit to suppress harmonic current. Other features include analog external control and monitor output, master-slave parallel operation function, various protection functions, memory functions, etc.
*Supported from Half-Rack Model Ver2.0
Equipment
Equipped with standard LAN interface and VMCB (Virtual Multi-Channel Bus) function
to support network-based remote control and monitoring
The PWX series is equipped with LAN, USB, and RS232C interfacesas standard features. By using the feature of virtual multi-channelbus (VMCB)*1, it allows you to control remotely and monitoringfor 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 controland monitor the power supply through a browser on a PC, smartphone,or tablet by accessing the web server built into the PWXseries.
Additionally, the optional application software, Wavy forPWX (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 youperform batch control using global commands*2. You can alsoturn the output ON and OFF on multiple units and adjust theoutput 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.
