come in a variety of forms for solving many different kinds of power problems,
provide surge protection, and some come with optional PWM (pulsed
width modulated) automatic voltage
regulation utilizing IGBT (insulated gate bipolar transistor)
technology. Some are also available in outdoor rated enclosures as
outdoor power conditioners. Please look at the table
below, or at the more detailed descriptions further down, to determine
the isolation transformer/power conditioning series you need.

ILc-1000B
ILc-1800
ILc-5500 |
ILc ~ single phase
These line conditioners provide the best all-round power conditioning and
surge protection for sensitive electronic equipment. The integral
low-impedance isolation transformer provides 100% isolation from the input
ac line. The secondary neutral-to-ground bond eliminates all surge voltages
between neutral and ground. Surge protection and noise filtering are
superior to conventional surge protection and filtering devices.
ILc Series conditioners reduce the need for a high quality ground and a
dedicated line, while eliminating interference from adjacent sources of
disturbances. ILc contributes to enhanced operation, improved repeatability,
fewer reboots and system lock-ups and extended operating life. In addition,
a reduction in equipment down time and service costs can be expected.
Designed for situations where reliability and
predictability matter to the enterprise.
Examples include: point-of-sale
terminals, telecommunications equipment, file servers, routers, digital
copiers, office machines, industrial controllers (PLC), automatic test
equipment (ATE), laboratory analyzers and other sensitive, specialized
microprocessor-based equipment.

ILc ~ three phase
Three phase low-impedance
isolation transformer line conditioners. The integral isolation transformer
provide complete isolation between the primary and secondary, and permits
bonding its output neutral to ground, which completely eliminates all
disturbances between neutral and ground, regardless of source. The series
inductance of the isolation transformer in combination with capacitive
elements and MOVs, provide superb noise filtering, as well as coordinated
multi-stage surge protection in accordance with the principles of
IEC-61312.3.
These are recommended for severe environments where
absolute reliability is a must. Applications include: sensitive telecommunications, radio base stations (RBS)/base transmitter stations
(BTS), transmission sites for backhaul (including microwave links),
industrial and medical equipment, and other sensitive, specialized
microprocessor-based equipment. The ILc series offers full transformer isolation with a
neutral-to-ground bond, excellent surge protection and noise
filtering, tolerance of frequency variations and unpredictable loads, high
efficiency, quiet operation and high reliability. The ILc series
comes with a limited five-year warranty.
ILc units come in various sizes, two common
international sizes are:
ILc-9000-16500 ~ 400V delta input, 230/400V wye output
Other sizes
and voltages are available. Please call.

ILc-VRp ~ single phase
The ILc-VRp dual range automatic precision
voltage regulator with built-in low-impedance isolation transformer allows
trouble-free operation of electronic equipment over a very wide ac voltage
range of 120 or 240vac +/-20% found in many developing countries. Output
regulation responds in less than one line cycle and corrects output voltage
to +/-2.5% with 20,000 corrections per second. There is no switching of taps
or otherwise a break in the power path as continuous PWM (pulse-width-modulation)
switching of the primary winding of a buck-boost
transformer leaves the
secondary power path intact.
ILc-2000-VRp-Dual-Range ~ 120V+240V, 2000VA

VRp-ILc-16500-0338 |
VRp-Ilc ~
three phase
The VRp-ILc automatic precision voltage regulator with built-in
low-impedance isolation transformer allows trouble-free operation of
electronic equipment over a very wide mains ac voltage range of 400V +/-20%
(+/-30% for short durations) found in many developing countries.
There is no
switching of taps or otherwise a break in the power path thanks to
continuous PWM (pulsed-width-modulation) switching of a buck-boost
transformer primary winding. Outstanding voltage regulation: under normal
input range of 400vac +/- 20%, output voltage per phase will be 230 vac +/-1% (47 to
63Hz). Units feature an over/under voltage cutoff, with automatic restart
when ac mains voltage returns to normal (safe) condition, below 300vac or
above 160vac. Failsafe: automatic bypass (even during bypass, the over/under
voltage protection is active).
These units are designed for
applications where absolutely safe and precisely regulated ac power is
required, such as mobile communications (GSM/satellite/wireless broadband),
radio base stations (RBS) /base transmitter stations (BTS), radio / TV
broadcasting, transmission sites for backhaul (including microwave links)
industrial process controller (PLC), medical (mobile MRI, CT) and laboratory
or analytical measurement equipment.
VRp-ILc-16500-0338, 16.5kVA, 400V delta
input, 230/400V wye output. Different sizes are available, please call for
more information.

Outdoor VRx ~ single phase
TSi Power’s Outdoor VRx precision PWM automatic voltage regulator with
optional built-in low-impedance isolation transformer allows trouble-free
operation of electronic equipment over a wide mains ac voltage range of 172
to 276V found in many developing countries. There is no switching of taps or
otherwise a break in the power path thanks to continuous PWM switching of a
buck-boost transformer primary winding. VRx is also designed with a
fail-safe automatic bypass which enables the VRx to provide power to the
load even in the event of internal failure that may otherwise result in a
disruption of power to the load. VRx with optional isolation transformer
provides complete isolation from the ac line, with a neutral-to-ground bond
to eliminate all surge voltages between neutral and
ground.
VRx-4400-0455-0460, 220/230/240V, 4.4kVA.
Other sizes
are available for different voltages.

Outdoor VRp-ILc ~ three phase
As above
three phase VRp-ILc Series, but the unit comes in a specially designed outdoor rated
enclosure with multiple air exhaust fans. To maximize cooling, the isolation
transformer is housed in an IP23 outer enclosure. Sensitive components are
housed in an IP55 inner case. Overall equivalent is to an IP44 (NEMA-3R)
enclosure. The automatic bypass assures that connected equipment will not
shut down, even if VRp-ILc fails. VRp-ILc is compatible with all loads as it
does not switch any components in the power path. VRp-ILc’s ultra-low
impedance assures stability even with the most demanding loads. The
automatic overvoltage cutoff with automatic restart ensures that operation
is off-line during serious overvoltage situations that could damage the
system and/or load, and then restarts without intervention when the ac mains
voltage returns to the normal operating range. The lightweight, high
efficiency outdoor VRp-ILc is easy to install in exterior
environments.
VRp-ILc-15000/30000-5339, 15kVA/30kVA, 400V delta in, 230/400V
