Si Powers VRp automatic precision regulator
line conditioner provides output voltage within
plus/minus 3% of nominal, for input voltage
that varies between 95 to 145vac.
There is no switching of taps or otherwise a
break in the power path thanks to continuous
PWM switching of a buck-boost transformer.
Typical 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
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. VRps ultra-low impedance
assures stability even with the most demanding
loads.
How the VRp Series works
The high frequency IGBT driven converter takes
the incoming ac power, measures against the
nominal voltage and adds or subtracts voltage,
20,000 times per second, 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 neu-
tral and ground. A separate isolation transformer is recommended for installations
where distance exceeds above, or for grounding systems without a neutral-to-ground
bond.
Ac output connection
Hardwired output terminals (hot, neutral and ground) are standard.
Optional input cord and output receptacles are available.
