Power supply circuitry
(only MAC800)
The MAC800 supply is split into 2 individual circuits with full galvanic isolation between
the circuits. The control circuitry requires a voltage in the range 18 to 30VDC and the
power circuity must be supplied with 90 to 240VAC (Set by solder jumper
supply voltage (only MAC800), page 67
). Having 2 independent supply circuits offers the
feature that the supply voltage for the power circuitry (90-240VAC) can be removed for
safety reasons, while the control circuitry can continue operating and thus keep the po-
sition counter updated and keep other vital functions such as communication active.
The circuit above is shown with an emergency relay (box) which can be omitted if the
application does not require this safety feature. There are shown examples of Emergency
stop and relay in section 5.6.2. The internal power dump is intended to cover 90% of all
applications but if the error message “overvoltage” is monitored, an external power
dump resistor must be connected between the terminals
PD
and
BO
.

Sizing the external fuse (Prefuse).
When using
115V
supply voltage:
To met UL requirements, the prefuse must be a class RK5 such as the type FRN-R-15
(15Amp.) from manufacturer: Cooper Bussmann INC.
When using
230V
supply voltage:
Prefuse T10A@230VAC type gG, Do or Dz in the phase line Rated for600V/150kA.
