Precision
Fast-PWM Ac Mains Voltage Correction
TSi Power’s VRp automatic precision regulator
line conditioner provides output voltage within plus/minus 3% of
nominal, for input voltage that varies between 185 to 265vac, per phase.
There
is no switching of taps or otherwise a break in the power path thanks to
continuous PWM (Pulse-Width-Modulation) switching of a buck-boost transformer.
Typical VRp
Applications
Designed for applications that require absolutely stable,
high-reliability power, without switching components in the power path.
Applications include, but are not limited to: analytical
equipment, radio and TV broadcast equipment, mobile broadcast vans,
industrial controllers (PLC), milking machines, lithographic equipment,
recording studio equipment and electrolysis equipment.
Key Benefits of
the VRp Series
The low-weight, high efficiency VRp is easy to install in any
environment. The automatic bypass assures that connected equipment will
not shut down, even if VRp fails. VRp is compatible with all loads as it
does not switch any components in the power path. VRp’s ultra-low
impedance assures stability even with the most demanding loads.
How the VRp
Series Precision Electronic AVR Works
The high frequency IGBT driven converter takes the
incoming ac power, measures against the nominal voltage and adds or
subtracts voltage, 10,000 times per cycle, to achieve the nominal output
voltage +/-3%.
The automatic bypass will be activated when there is a fault
condition. Green LED indicates Normal (regulating mode operation),
Yellow LED indicates Bypass (non-regulated output), and the Red LED indicates a Fault condition. |

Note: Unit
should be installed as close as possible (within 30’) of
the neutral-to-ground bond at the service entrance, in order
to minimize potential difference between neutral and ground.
A separate isolation transformer is recommended for
installations where distance exceeds above, or for
grounding systems without a neutral-to-ground bond.
