Aim TTi LD400 Electrical load 80 V DC 80 A 400 W

Electronic DC load LD 400

The LD400 is a low-cost electronic load for the testing and characterization of a variety of direct current sources.
It can be used to set the behavior of many different types of power sources such as batteries and solar cells as well as electronic power supply units to investigate.
Its wide voltage/current range, multiple operating modes and a built-in test generator give it the versatility for test solutions from the design laboratory through to the component test area.

Facts

• Low minimum input voltage
• The LD400 may, at voltages below 500 mV for currents up to 10 Ampere. At higher currents increases the fixed minimum resistance (typically better than 25 mW) gradually increase the minimum operating voltage, but he remains below 1 Volt up to 40 Ampere and below 2 volts up to 80 Ampere.
• This low operating voltage makes it possible for many low-voltage applications to be used for the other electronic loads are unsuitable.
• 600 watts of peak power
• The LD400 can take up to 1 minute with a maximum power output of 600 watts can be operated
• Short-term loads can be sufficient for many test applications and extend the usability of the LD 400 considerably. The continuous power is 400 W.
• Several Operating Modes
• Constant current mode
• The constant current mode is for the load testing of normal power supplies and for the constant current discharge of batteries. This mode allows for a quick measurement of the current source control (V/I curve).
• Constant power mode
• The constant power mode simulates a load, their power input, regardless of the applied voltage. This applies to many types of devices, the switched-mode power supplies. This mode is particularly suitable for testing power sources of portable devices such as lithium-ion batteries.
• Constant voltage mode
• The Constant voltage mode is used for the load testing of constant power supplies. The device works as a high-performance shunt regulator.
• Constant resistance mode
• The constant resistance mode simulates a standard resistance load by providing a current flow, which is proportional to the voltage. The settings are in ohms or milli-ohm.
• In contrast to fixed resistors and rheostaten offers the load a precisely controllable resistance with high power loss and high temperature stability over a wide frequency range.
• Constant conductance mode
• The Constant conductance mode is also included.
• In addition to the settings in ampere per volt offers this mode a better resolution in the setting of very low equivalent resistance values.
• Fully automatic test generator with variable frequency
• Switching between the two preset levels, for each frequency between 0.01 Hz and 10kHz. The test generator can be used in all operating modes.
• The change rate between the levels (Slew Rate) is controlled over a wide range.
