Embedded Web
The PXB series is a bidirectional DC power supply that can be connected via a LAN interface, allowing you to configure output settings such as voltage and current, as well as turn Output ON/OFF, directly from a web browser. The unit’s front panel is displayed on a PC or tablet, enabling remote operation with the same feel as operating the unit directly.
External Control
Control is performed via the EXT-CONT connector on the rear of the unit.
It consists of 4 analog I/O ports and 12 digital I/O ports.
The digital I/O ports are general-purpose ports, and any function can be assigned to them from the operation panel.
