Three phase thyristor for
simple resistive and inductive loads TC 3000
Three phase thyristor for simple resistive and
inductive loads
The TC3000 is a full three phase thyristor power unit for all constant resistance or
inductive three phase loads. Three wire star or delta, four wire star with neutral and six
wire open delta load configurations can be used. It has all the firing modes needed for
simple resistive and inductive loads including phase angle for inductive loads, single cycle
for off-shore and generator applications, fast cycle for quick acting heaters and slow cycle
for very large loads. Since it is a true phase unit the TC3000 fires evenly on all phases to
match the load to the generator or supply. The self contained units are available for
currents up to 500amps.
Safety - As with all Eurotherm products the TC 3000 has been designed to ensure
operator safety and load protection. When installed and used in compliance with user
manual HA174836 it meets the essential requirements of the EEC Low Voltage Directive.
The self contained units are fully shrouded in an IP20 rated protective case with
commissioning and diagnostics points available on the front fascia. High speed
semiconductor fuses and other protection circuits are built in. Automatic alarm shutdown
protects the load and supply by quenching the thyristors if the unit detects an abnormal
event.
CE mark- The TC3000 is CE marked to show compliance with the essential protection
requirements of the Low Voltage Directive. It is designed so that it can be used as part of
a CE compliant system but it is the responsibility of the installer to establish the CE
compliance of the overall system. The TC3000 technical construction file is approved by a
Competent Body (LCIE France). A Declaration of Compliance with the European
Directives is available on request.
EMC- Eurotherm certifies that the TC3000 products, when installed and used in
accordance with their User Manual, meets the following test standards and enables the
system or installation in which they are installed to comply with the EMC Directive with
regard to the TC3000 products.

The choice of the Conducted Emission application standard depends on the
application:
· EN50081-2 (1991)
- Without external filter in Burst firing on resistive load up to 150A nominal
- With an external series filter for other configurations
· prEN 61800-3 (1996)
- Without external filter
Applies to the second environment (industrial environment)
External series filters
To reduce the conducted emissions that occur when using thyristor units, Eurotherm can supply
external filters.
