1.9.3 MONPS/MONPSE Board (Power Supply Circuit Board)
The power supply circuit board is located on one of two boards, the MONPS for 120 V AC operation
and the MONPSE for 220/240 V operation. The basic construction of the two boards is the same: each
board contains a power switch, fuses, line filter circuit, and switching regulator circuit. Compactness
of the circuitry is made possible by use of a DC-to-DC converter.
