NOVAR Power Factor ControllersDevelopment and production of power factor controllers NOVAR is one of company's most important activities. In the following overview the devices for fully automated and optimal compensation of reactive power are presented. Portfolio includes classic power factor controllers operation with electromechanical contactors as well as components for fast compensation systems - fast power factor controller and thyristor switching blocks.

New line of PFC with enhanced sensitivity, 6/14 outputs  NOVAR 1xxx-line power factor controllers are fully automatic instruments designated for optimal compensation of reactive power. They are suitable for PFC application which requires precise control even under low load. These new products are compatible (in terms of wiring) with previos NOVAR 1xx devices.

For fast compensation, improved sensitivity, 12+2 outputs  NOVAR 1312 reactive power controller (governor, PFC) is designed for compensation systems where conventional governors with relay outputs to control circuit breakers do not meet special requirements. These are usually systems where rapid frequent changes in reactive power take place or systems with strict requirements on electromagnetic noise suppression and power quality.

Simple, fully autonomous budgetary PFC NOVAR 1005 and 1007 power factor controllers are enhanced successors of very popular budgetary NOVAR 5 controller. These models are primarily intended for smaller and less demanding application. In compare with the NOVAR 5 their current sensitivity was increased. The NOVAR 1005 controller is fully backward compatible with the NOVAR 5 model. Furthermore, the NOVAR 1007 has 8 output relays. The controllers are also available in DIN-rail-mount version as Novar1005D/1007D.

 Three-phase PFC,14 outputs
NOVAR 1414 power factor controller is designed for applications with
great or variable load unbalance. It measures currents of all three
phases and evaluates three-phase power factor which value is used for
the control. The design is based on the NOVAR 1214 model - the two additional current inputs is the only significant difference. |

|
Thyristor switching modules  Thyristor switching modules of the KATKA line have been designed especially for switching power factor correction capacitors in rapid reactive power compensation (up to 20 control interventions in one second) in conjunction with fast power factor controllers of the NOVAR line. They can be also used in other applications where contact-less load switching is required.

6/14 outputs, measuring voltage common with supply voltage 
Production stopped.
See NOVAR 1106/1114 for replacement. Power factor controllers NOVAR 106 and NOVAR 114 are fully automatical instruments designated to optimal control over compensation of reactive power. Both are intended mostly for demanding applications. |

6/14 outputs, measuring voltage separate 
Production stopped.
See NOVAR 1206/1214 for replacement. Power factor controllers NOVAR 206 and NOVAR 214 are fully automatic instruments enabling optimal control over compensation of reactive power. These devices are designated for middle- to very-demanding applications with non-standard voltage being measured.

Simple and compact, fully automatic PFC 
Production stopped
see NOVAR 1005/1007 for replacement. NOVAR 5 is a power factor controller designed for less demanding applications. Its biggest merit is its low price and simple usage. The 5+ modification of this instrument is adjusted to operate in rougher conditions. |

|
Replacement for RQ5  Novar 5 RQ power factor controller is a direct replacement for older type of PFC from ZEZ Horice. Replacing is straightforward as NOVAR 5 RQ is mechanically fully compatible with RQ5.
Mostly for Czech market and where replacements of the old PFCs are needed. |
