16 CSW Series
Function Specification
External Gain Control, RPV 0 to +7.07 VDC for 0 to programmed output. 0 to full-scale output for CSW.
(±2% of full scale output
External Input Impedance 40K for each of the three inputs.
XLOAD The CSW5550 is guaranteed to be stable for power factors from 0 leading to 0
lagging. The most difficult load for most amplifiers is driving large capacitive
loads (10-10,000F).Though stable with its normal loop compensation, the
CSW can provide additional phase/gain margin with these unusual loads by
selecting XLOAD On. This significantly improves the transient response of the
amplifier.
X-Load should only be used for reactive loads, and with programmed
frequencies of less than 1000 Hz.
Output current for which specifications apply is de-rated for frequencies above 400Hz as a function of
voltage, and for maximum power of 1850 VA per phase, as shown in Figure 2-1 and Figure 2-2.
