NOVAR Power Factor Controllers

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 previous NOVAR 1xx devices.

NOVAR 1312 and NOVAR 1312-3 reactive power controllers (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.

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.

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.

The NRC 86 remote controller is designed especially for large photovoltaic power stations connected to high voltage distribution networks that require remote control of target PF through pulse inputs. Another option of the controller application may be compensation system with remote controlled outputs. The controllers are installed in set with special version of „NOVAR 1xxx NRC“ PFCs.
