The TC3000 SCR assembly is a general purpose three
phase power controller for all constant resistance or inductive
loads up to 500A/500Vac. The TC3000 fires evenly on all phases
to match the load to the generator supply. Three wire wye or delta,
four wire wye with neutral and six-wire inside delta load configurations
can be controlled. Resistive load firing modes include logic firing
for action as a solid state contactor, single cycle for special
applications, fast cycle for quick acting heaters and slow cycle
for large loads. Phase angle firing is available |

for inductive
loads. Inputs are logic or analog. The TC3000 is phase rotation
insensitive. The unit is shrouded in a protective cover with commissioning
and diagnostic points available on the front. Protective measures
include built-in high speed fuses with optional fuse-fail microswitches,
snubbers and varistors and SCR quenching action on any of several
operational alarm conditions. Cooling at 100A and up is by fans,
with over-temperature shutdowns. It may be used with the model
260 Diagnostic Unit. |
