3.1 RFD-200 S2 Auxiliary Power Supply
The RFD-200 S2 provides 3 auxiliary power supplies (24Vdc, 124Vdc, 240Vac) to
power electronic relays. Each power supply is fuse protected.
These power supply outputs are controlled by the AUX PWS ON/OFF switch. A LED is
lit to indicate when power supply output is turned on.
Only one of the auxiliary power supply can be selected at a time. The PWS SELECT
switch allows the user to select which power supply is to be used. An active power
supply is indicated by a lit LED.

3.2 RFD-200 S2 Current Source and Voltage Sources
Three current source terminals (100A, 40A, 10A) are available on the RFD-200 S2 front
panel. Output current is displayed on the LCD when the “RFD-200 CURRENT” LED is
lit. Use “METER SELECT” switch to select whether to display current generated by the
RFD-200 S2 or the current input at the “EXT INPUT CURRENT” terminals.
Figure 3 RFD-200-S2 Current and Voltage Sources
One isolated 0-250Vac and one isolated 0-300Vdc voltage sources are also available
along with the three current sources. Both the current and voltage sources are controlled
by the Output Control knob (see Figure 4).
