The WCL488 Water Cooled Electronic Loads are ideal for high current/high power battery,
power supply and fuel cell testing. Standard systems from 12kW to 120kW are configured using
12kW standard products in a master/slave configuration. Each 12kW unit is rated at 0-100V or 0-
400V, 0-1000A (1200A for the 50V model), not to exceed 12,000W. Larger systems are available
upon request.
The WCL488 master unit measures 5-1/4 inches high and the slave unit measures 3-1/2 inches
high and both fit into a standard 19-inch wide equipment rack. The compact size of the units and
our unique plumbing design allows 120kW of power dissipation in a single 60 high rack.
Systems may be upgraded by adding slave units. The manifold plumbing design and complete
DC bus structure allow for simple upgrade in the field.
Individual units' electrical inputs and water inlet and output connections are located on the rear of
each unit. Single connections are provided for systems unless otherwise specified.
Standard features for the WCL488 Series include the following:
Operation below 1 Volt at 10,000 Amps (50 Volt model only)
Five modes of operation: Constant Current, Constant Resistance, Constant Power,
Constant Voltage, Pulse Mode
Full Scale Range Switching: When a scale is selected, it changes the controls and
instrumentation to correspond with the selected scale, for increased resolution and
accuracy.
Synchronized paralleling creates larger systems controlled as a single unit
Automated flow regulation to eliminate condensation
Lab View drivers are available for computer control
Self configuring based on number of slaves in use
Units available include:
50 Volts, 1200 Amps, 12000 Watts
100 Volts, 1000 Amps, 12000 Watts
400 Volts, 1000 Amps, 12000 Watts.
Highest Density Solution: Complete 120kW system only 60 inches tall
Constant Current, Resistance, Voltage, Power
Modular design using standard building blocks
