Introduction
The XBL Series single channel loads are ideal for testing power supplies, fuel cells, large
batteries, and other related DC power equipment.
The high range current capability and constant power feature facilitate battery testing and
analysis. The ultra-fast slew rate provides unmatched power supply transient testing capabilities.
The ultra-low voltage, high current capability makes the XBL Series an ideal solution for most
fuel cell requirements.
Standard Features for the XBL Series include the following:
Ratings from 0-1000 Volts (XBL 1000V only), 0-1000 Amps, up to 6000 watts in a single
unit
Units available include:
800 Watt (8 inches W x 5.25 inches H x 22 inches D)
2000 Watt (19 inches W x 5.25 inches H x 22 inches D)
4000 Watt (19 inches W x 8.75 inches H x 22 inches D)
6000 Watt (19 inches W x 10.5
inches H x 22 inches D)
Variable speed fans minimize fan noise (standard on 2000W , 4000 and 6000W only)
Operation below 0.5 volts at 1000 Amps (On 50V, 1000A units only.)
Five modes of operation: Constant Current, Constant Resistance, Constant Power,
Constant Voltage, Pulse Mode
Full Scale Range Switching: for increased resolution and accuracy
Synchronized paralleling to create larger systems that are controlled simultaneously
Internal pulse generator for transient testing (Slew is not adjustable in pulse mode)
Lab View drivers are available for IEEE-488 computer control.
Ethernet control
XBLs have a remote user interface are available.
