Determining Line Frequency
The SHPF2/SHPF3 is designed to operate on either 50 or 60 Hz. Usually the SHPF2/SHPF3 is
shipped for 60 Hz operation, unless otherwise ordered. The SHPF2/SHPF3 can be set for either ac
line frequency by selecting 50 Hz or 60 Hz on SW3 on the control board on the inside front door.
3.7 Voltage
Changeover
On occasion, customers may wish to operate a SHZF2/SHZF3 SCR Power Controller on line voltages
other than what was specified when originally ordered. The SHZF2/SHZF3 may be changed to accept
a wide range of line voltages (120, 240, 400, 480, 575 Vac), so long as the load current does not
exceed the SHZF2/SHZF3’s current rating. This is accomplished by performing the procedure
described below.
Using the system schematic (located in the Appendix) as reference, perform the voltage changeover
procedure as follows.
1. Open the SCR power controller, and locate transformer T1. The primary side of T1 transformer
will contain two wires (one black, the other white and black). Refer to Figure 3.3.
WARNING
Voltage changeover should be performed by qualified personnel only.
Always remove power and properly lock out power to the unit before
attempting any service.
