5.2 POWER DISTRIBUTION

TECHNICAL REFERENCE MANUAL DEK TQ 04/2021 53

5.2 POWER DISTRIBUTION

Mains Input Power from the facility (110V to 230V ±10%, 50 to 60Hz A.C.) is routed to the Mains

Isolator Switch at the front of the machine. From the isolator, the supply is fed via an EMI line filter

and surge suppressor to the M71 Power Supply Enclosure, through a cable gland at the rear. In-

side the M71 Enclosure, the cores of the mains cable connect to the three terminal blocks: TB1

(Live), TB2 (Neutral) and TB3 (Earth/Ground). From the terminal blocks, mains power is distributed

to the following loads:

●

M71SK34 Temperature Control Unit (via CB2 on the front panel)

●

M71SK35 Internal Vacuum Pump (via CB2 on the front panel)

●

M71SK36 Display Monitor (via fuse M71F1 on the front panel)

●

24V DC PSU (via CB1 on the front panel)

●

48V DC PSU (via CB1 on the front panel)

The D.C. supplies from the PSU are fed to the power distribution PCB (some via the safety cir-

cuits), which mounts the enclosures rear connectors. Connected to this PCB is the PSU monitor

board, which provides a USB link to the P.C., allowing software to monitor the levels of D.C.

voltage present on the distribution PCB.
