TEALtrak® Voltage Regulation
The TEALtrak® Voltage Regulator product is a high-reliability dual-conversion power-conditioning device that is designed to regulate and stabilize three-phase AC voltage sources.
The TEALtrak® Voltage Regulator product line is based
on an industrial voltage regulator unit that is integrated with our ultra high
reliability isolation transformer based product for applications or installations
that require a stabilized voltage source.
The TEALtrak® unit is an active microprocessor
controlled device that
converts the incoming mains AC into DC, then inverts and tightly regulates
the DC back into a clean, filtered and stable AC source. The regulated AC is
then coupled with filtering, surge suppression, and a TEAL isolation transformer
(for voltage conversion, distribution, and single-point grounding) to make a
complete power conditioning package.
TEAL Power Subsystem with integrate TEALtrak® Voltage
Regulation, Isolation Transformer, Output Distribution,
Controls, and Protection.
TEALtrak®
Benefits:
Protects the customers electronic equipment from damaging or disruptive voltage sags,
swells, spikes, and transients including Power Factor Correction (PFC) transients
induced by the facility or utility.
Sub-Cycle response enables correction of line voltage during transient events.
High peak power capability ideal for driving switch-mode power supplies (SMPS)
or non-linear loads.
Continuous voltage regulation eliminates the step-changes in voltage associated
with old-style tap-switching voltage regulators, reducing noise and errors in the image.
TEALtrak® Features:
Standard units for power ranges of 30kVA to 150kVA.
Standard output voltage regulation of +/-5% with an input voltage of +10%
to –20% from nominal.
Rugged industrialized continuous voltage regulation with no discrete step
changes or double-tapping.
Sub-cycle (<4ms) response time to help correct fast transients on the AC
mains without overshoot.
Frequency stabilization and correction with high power conversion efficiency
(>85%) at full load.
High reliability dual-conversion technology converts the mains AC to DC then
inverts back to a tightly regulated AC, eliminating the typical failures of the
old-style tap-switching voltage regulator.
Uses rugged industrial microprocessor controlled motor drive controller as
the core “engine”.
Meets IEC 801-2 for Electromagnetic Emissions.
Controls include ON/OFF, Emergency Power OFF (activated through a Shunt-Trip
with customer accessible contacts), and BYPASS of Voltage Regulator section that
allows the mains AC to be diverted to the load even in the unlikely event of a
voltage regulator failure.
Indicators include Power “ON” and “OUT OF SPEC” with
customer accessible dry contacts for each.
