POWER SUPPLY M37
OVERVIEW
5.6 Technical Reference Manual Chapter Issue 13, Jan 17
WARNING
LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS EQUIPMENT.
ENSURE ALL ELECTRONIC COVERS AND MAIN MACHINE COVERS ARE FITTED
BEFORE OPERATING THIS EQUIPMENT.
Mains input power (100V to 240V) to the machine is routed to the mains isolator
switch at the front of the machine. From the mains isolator it is fed to the M37
power supply crate, through the cable gland at the rear panel, to the three
terminal blocks TB1 (live), TB2 (neutral) and TB3 (earth). From the terminal
blocks mains power is supplied to the following:
• M37SK31 PC Supply
• M37SK32 Monitor Supply
• M37SK33 Spare
• M37SK34 Spare
• M37SK35 Internal Vac Pump via Mains Filter and CB34
• PSU
The PSU is a Switched Mode Power Supply Unit (SMPSU) which converts the
ac into the following dc supplies:
•+24V US
• +24V SW
•+5.5V
•+12V
•-12V
•+42V
• +48V (See note)
NOTE
The PSU upper voltage is set to +42V except for Type 1 machines that are set
to +48V.
The dc supplies from the PSU are fed to the power distribution PCB. Mounted
on the power distribution PCB is the PSU monitor board which enables moni-
toring of the power supplies.
An E Stop loop, front cover interlock, rear cover interlock/interlock blanking plug
and E Stop relay are fitted to ensure motor power is removed if the front
printhead cover or rear cover is opened or the machine is crash stopped by
pressing an E Stop button.
A two handed safety relay, left jog button and right jog button are fitted to enable
certain functions to be performed with the front printhead cover open.
The M37 power supply crate has mains power available; when access to the
components of the enclosure is required, observe the following warning:
