13.0 OPERATING INFORMATION
13.1 Input Voltage and Connection.
The AC version of the PowerCassette operates off worldwide
AC input voltages in the range of 85 to 264 VAC at 47 to 63 Hz. The three-wire AC connection
is made to pins 45-47 on the large Positronics connector. Mating connector kits for both
AC and DC inputs are available. See the connector diagram and Pin Connections table in
Figure 5. Also available is a Mating Interface Board with screw terminal connections. See
Appendix A5. The DC version of PowerCassette operates from a wide range 36 to 72 VDC
input. The three-wire DC connection is made to pins 48 to 50 of the small, separate DC
input connector shown in Figure 5.
13.2
Output Connections.
The output voltages are provided on pins 1 to 24 of the large Positronics
connector. V1 and V2, the highest current outputs, use a series of paralleled pins for the
currents. All output returns are connected together internally, but each return should be run
separately to its respective load.

*NOTES
: For unit to operate, pin 27 must be at logic LO or shorted to pin 22. Pin 39 should be connected through a 10k ohm resistor to Pin 26.
Pins 25, 28, 38, 40 and 43 function as I²C outputs when that option is present. All returns and signal ground are connected together.
