Rectifier Overview
The rectifier provides load power during normal operating conditions. The rectifier is a constant
power design. The rectifier is rated at its maximum output power. This means that, within the
normal operating ambient temperature range and input voltage range, the maximum available
output power is a constant 2000 W. Within these ranges, the rectifier operates in one of three
modes, depending upon load demands. Transition between modes is completely automatic. If
ambient temperature rises above or input voltage falls below acceptable values, the rectifier
continues to operate but at derated output power levels.
•
Constant Voltage Mode: For any initial output voltage setting from -42 VDC to -58 VDC
(factory set at -54 VDC), output voltage remains constant regardless of load. This is the
normal operating condition, in which loads are being supplied. The rectifier operates in the
Constant Voltage Mode unless load increases to the point where the product of load current
and output voltage is approximately 2000 W.
•
Constant Power Mode: As load increases above approximately 2000 W (non-adjustable),
output current continues to increase, but output voltage decreases as required to maintain
constant output power. The rectifier operates in the Constant Power Mode unless load
continues to increase to the point where the current limit setting is reached.
•
Constant Current Mode: If load increases to the current limit setting, output voltage
decreases linearly to maintain output current at the current limit setting.
