Introduction
The MCS2000-PSDRV2 Power Supply/Dual
Channel/Dual Voltage driver is a replacement for
the MCS2000-PSDRV and MCS2000-PSDRVH
Drivers in a single unit. The Power Supply section
will operate from 100 – 260 VAC and provide a 24
VDC output for operating either the driver section
of the unit or the MCS2000-ECA and other
sensors. The Dual Channel/Dual Voltage driver
section will operate from either 24 volts DC input
or 48 volts DC input and provide output voltage
and current for operation of any of the 24 volt DC
tension brakes available from Warner Electric.
The universal design replaces two separate power
supply/drivers in one package and provides for
dual brake operation, for either single brake when
only one brake is required or dual brake operation
on splicer systems where two brakes are required.
The driver can be controlled by any of the
MCS2000 controllers offered as either a single
channel system or dual channel system. The
MCS2000-ECA, MCS2000-CTDA, or
MCS2000-CTLC controllers can provide the
operating signals. The MCS2000-PSDRV2 has
reduced input terminals on the front of the unit for
the driver section that are pluggable which will
make installation and wiring much easier than the
previous versions. By using a pluggable terminal
block, if replacement is required then only the
controller has to be disconnected and removed
and a new controller installed without having to
rewire the entire system.
Footprint for the PSDRV2 is identical to that of the
MCS2000-PSDRV and MCS2000-PSDRVH power
supply/drivers. The MCS2000-PSDRV and
MCS2000-PSDRVH can be replaced with the
MCS2000-PSDRV2 without having to make any
mechanical changes in the mounting footprint.
Additionally, LED indicators on the face of the
control make troubleshooting and monitoring
operation much simpler than previous versions. A
combination red and green LED for each channel
determines operation during normal run
conditions as well as during faults.
Each driver channel has its own individual
anti-residual adjustment to make brake
adjustment in the “off” state optimum.
Anti-residual provides a reverse current to the
brakes in the off state to minimize residual
magnetism build up. This allows for reducing the
drag torque in the brake during initial start up.
