The LD400 is an inexpensive 400 watt electronic load which is suitable for testing and characterising a wide variety of dc power sources.
It can be used to investigate the behaviour of many different types of power source such as batteries and solar cells, as well as electronic power supply units.
Its wide voltage/current range, multiple operating modes and built-in transient generator give it the versatility to offer test solutions from the design laboratory through to the component test area.
The LD400P adds full bus remote control via USB,
RS-232, GPIB and LAN (Ethernet) interfaces.80 volts, 80 amps and up to 600 watts Subject to its maximum power ratings, the LD400 can operate at up to 80 volts or up to 80 amps.
It can operate at power levels up to 600 watts for periods of up to 1 minute. Short term loading can be sufficient for many testing applications and significantly extends the usefulness.

Comprehensive Bus Remote Control To meet a wide variety of needs, the LX400P adds a comprehensive array of digital bus interfaces. RS-232, USB, GPIB and LAN (Ethernet) with LXI support are all provided as standard.
Each of the digital bus interfaces provides full control of and read-back of settings and status. The interfaces are at ground potential and are opto-isolated from the terminals.
The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. Currently GPIB remains the most widely used interface for system applications.
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 load devices 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 operating systems.
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 highly appropriate for system use because of its scalable nature and low cost interconnection.
The LAN interface is LXI compliant.
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.
