Tripack Multi-Phase Power Modules
Part No. 830-0168V2 (distributed over three phases)
Part No. 830-0168 (distributed over one phase)
Software T93300
The Tripack power module (dimension 15 D x 14 W x 9 H (380mm x 356mm x 230mm))
is recommended for welding stations that require multiple controls in limited space.
The power module has three sets of 1200 amp SCRs, firing boards and current
monitoring sensors. Three intelligent MedWeld 3005 resistance-welding processor
modules are included for installation in the Allen-Bradley
TM
SLC 500 rack. This kit
requires three interface cables (Part No. 205-1212Vx) purchased separately. The kit
is completed with user manuals and drawings. Software T93300
First time integrators must register the kit by purchasing the "Integrator's
Documentation Kit" (Part No. 830-0152) in order to facilitate quick ladder software
instructions.
The CE mark applies only to the MedWeld 3005 Resistance Welding Processor
Module (917-0050)
Please refer to the section on
programming devices for editing and
reviewing data and parameters stored
in the MedWeld 3005 module.
Please refer to the Interface Cables
table.
Tripack power module viewed from the
bottom. The return line from the weld
transformer must go through the
appropriate current monitoring coil that
is found beneath the SCRs.
WTC welding controls provide a load resistor across the welding transformer. This resistor
assures proper SCR firing and transient voltage suppression under all operating conditions.
The load resistor supplied as standard equipment is designed for spot welding or short
duration seam welding use with a maximum
weld time of 5 seconds and a maximum duty cycle
of 33%. If your welding application involves weld times longer than 5 seconds per weld or an
overall duty cycle exceeding 33%, a larger load resistor is required. Please contact the factory
or your sales representative to obtain the correct load resistor for your application.
