Product Overview
A standard feature of the networking capability provides extended applications of the ordinary testing.
The PMX-A Series consists of compact, high-performance constant voltage (CV) / constant current (CC) DC power supplies. To enhance work efficiency for benchtop use, all models feature front-panel output terminals and are ergonomically designed to allow for the natural connection of load harnesses.Moreover, a forced air cooling system is used to intake and exhaust of the in-ternal air, so the unit can be rack mounted without space. Furthermore, the PMX-A is equipped with LAN, USB, and RS232C interfaces as standard interfaces required for sys-tem operation. In particular, the LAN interface enables you to control and monitor the power supply from Web browsers on PCs, smartphones, tablets, and other terminal devices.Moreover, the PMX-A is LXI (LAN eXtensions for Instru-mentation) certified product, so it can be connected easier with your measurement system using LAN interface.The PMX-A is also equipped with remote sensing (for 18 V, 35 V models only), analog external control/monitoring output, various protective functions, memory function, and other functions.Series regulator system with excellent noise performanceThe PMX-A is based on the capacitor-input type of the series regulator design and which output can be generated with low noise and low ripple compared to the switching regulator design.
Features
Series regulator system with excellent noise performance
A standard feature of the networking capability provides extended applications of the ordinary testing.
The PMX-A series is equipped with LAN, USB, and RS232C interfaces as standard communication interfaces. These interfaces enable re-mote control and monitoring to be performed efficiently in 1-to-N node configurations as well as in N-to-M node configurations even under large-scale networks. In particular, the LAN interface enables you to control and monitor the power supply through a browser on the PC, smartphone, tablet, or other terminal devices by accessing the built-in Web server of the PMX-A series.
LAN Interface
The LAN interface 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 it 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.
AUTO MDIX function: The PMX-A 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 12 Mbps (es) (Full Speed).
RS232C interface
It can be used for communication with PCs and sequencers.
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 PMX-A series for convenient control and monitoring.
Analog Interface
The PMX-A series is equipped with external voltage/resistance control, which are interfaces necessary for analog external control and monitoring applications for test power supply devices. The input external signal and the output status signal can be conducted through the J1 connector on the rear panel.
Control of Output voltage and Output current
Control by external voltage (Vext)
It is possible to control the output voltage and output current of the PMX-A series by using an external voltage.
External control by external resistor (Rext)
外部に接続した抵抗を可変することで、PMX-Aシリーズの出力電圧・出力電流をコントロールする事が可能です。
Turning output on and off
Control using an external contact (S)
It is possible to turn the output ON/OFF of the PMX-A series by using an external contact.
