Features

A standard feature of the networking capability provides extended applications of the ordinary testing.
The PMX-A series is a compact, high-performance DC pow-er supply that provides constant voltage (CV) and constant current (CC). It is designed to improve working efficiency for benchtop uses. For this purpose, the output terminals are located on the front panel and are ergonomically designed so that wiring harnesses for electrical loads can be con-nected by moving your fingers naturally.

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 performance
The 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.

Improved usability
Ergonomically designed for the wiring load harness. The handle makes you easy to carry.

*1. 117 Vac, 200 Vac, 217 Vac and 234 Vac are factory options. *2. Excludes the charge current component that flows through the capacitor of the internal EMC filter circuit immediately after the POWER switch is turned on (for approximately 1 ms). *3. With the rated load. *4. When the output is on, hold down SHIFT and turn the VOLTAGE or CURRENT knob to change the value at 1/10th the resolution of the minimum digit. When the output is off, hold down SHIFT and turn the VOLTAGE or CURRENT knob to change the value at increments of 1 in the minimum digit. If you are setting the value through the communication interface, you can set the value at 1/10th the resolution of the minimum digit, regardless of whether the output is on. *5. 100 Vac to 90 Vac or 100 Vac to 110 Vac, rated load. *6.
