TTi PLH-P Series Interfacing to every application
Bench and System use
The PLH-P series includes all of the manual control features of the PLH series, but adds comprehensive remote control facilities.
The ultra-compact rack-modular sizing makes it ideally suited to rack mounted system applications, while its user-friendly manual controls are retained for bench top applications.
Rear Power Terminals
Power output terminals are duplicated on the rear panel for rack mount applications or other situations where rear connection is more appropriate.
Digital Remote Control
To meet the varying needs of today’s engineers, a comprehensive array of interfaces is provided. RS-232, USB and LAN (Ethernet) with LXI support are provided as standard. An additional GPIB interface is also optionally available.
Each of the digital bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage, current and status. The interfaces are at ground potential and are opto-isolated from the output terminals.
An RS-232/RS-423 interface is provided for use with legacy systems. This type of serial interface remains in common useage and is perfectly satisfactory for the control of power supplies because data speed is not an issue.
USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use. A USB driver is provided which supports Windows 2000, XP, Vista and Windows 7 (including 64 bit versions).
LAN-Ethernet with LXI
The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct connection to a single PC. This interface supports LXI and is the most appropriate for larger system use because of its scalable nature.
The LAN interface is compliant with LXI-C. LXI (LAN eXtensions for Instrumentation) is the next-generation, LAN-based modular architecture standard for automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems. For more information on LXI and how it replaces GPIB, or operates along side it.
An IVI driver for Windows is included. This provides support for common high-level applications such as LabView*, LabWindows*, and HP/Agilent VEE*.
GPIB (option G)
Further versions of the products, are fitted with a GPIB (IEEE-488) interface in addition to USB, RS232 and LAN.
Isolated Analog Remote Control
PLH-P units include isolated analog voltage control of both voltage and current. Analog control outputs (non-isolated) are also incorporated to enable easy parallel connection of multiple units in a master-slave configuration. Terminals for remote on/off control are also provided.
PLH-P Additional Facilities
From the front, PLH-P models are identical to standard PLH models and retain all of their manual control features.
The rear panel carries RS-232, USB and LAN (Ethernet) connectors, together with isolated analog in and non-isolated out for voltage and current, plus remote on/off control. Power output terminals are also duplicated on the rear panel.
All models can be additionally fitted with a GPIB interface (option G – factory fit only).
Up to four single output units can be fitted into one rack width. Alternatively, where PLH units are being used along side New PL units, a combination of singles and duals can be used i.e. one dual plus up to two singles.
The TTi RM450 rack mount is 4U high and incorporates limited ventilation space above and below the power supplies. Blanking plates are provided for unused positions.
