Itech IT8900 series DC loads

Itech IT8900 series DC loads

The Itech IT8900 series DC loads are high-performance programmable DC loads for inputs from 2 kW tot 54 kW. In master-slave parallel circuit a power rating of up to 384 kW can be obtained. These loads are solid and can be overloaded for a short period of time. IT8900A/E loads works for currents up to 2400 A in a 24U rack and are available in three voltage ranges: 150 V, 600 V and 1200 V.

Features of the IT8900A/E series DC loads

The electronic loads of the IT8900E series are able to work in CC, CV, CR or CP mode. On top of these modes the IT8900A offers CC+CV, CV+CR, CR+CC and CP+CC mode. This way a wide range of tests can be carried out. A selection of the innovative features available in the above modes is:

• Analog control function by PLC 0-10 V or by using a signal generator.
• Adjustable CV loop speed
• CC/CV mode remains available in parallel operation of several units.
• The latest CC+CV mode solves the problem of short surge currents
• CV+CR operation makes it possible to simulate the ripple when testing LED drivers.
• Dynamic tests up to 10 kHz with the E-series and up to 30 kHz with the A-series 150 V
• A soft start and soft stop on the IT8900A models.

You will find features for battery testing, automatic testing and short circuit testing. Each model in the IT8900A and E series high-performance DC loads has precision and real-time voltage and current measurements  The settings can be saved for recall at any time. Power-off preserves the last settings.

Control is analog, via the front panel or via a host computer. The host can be connected via RS232, USB, GPIB, CAN en LAN. De IT8900A/E can be programmed via a SCPI command set. For the IT8900 series DC loads there are also several software tools available, as well as the Labview drivers.

This load has extended protections: OVP, OCP, OPP, OTP, reverse connection, current limit and power limit protections.
