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.
Characteristics- panel vesion footprint 96 x 96 mm, DIN-rail version size 105 x 90 mm
- 6 or 8 controll outputs
- current measurement sensitivity 0,02 A
- high current and power factor measurement accuracy
- precise measurement and control functions even under conditions of voltage or current waveform distortion

Control Principles- governor’s speed of response independently programmable for conditions of under-compensation and over-compensation, respectively
- the preset speed of response increases in proportion to instantaneous control deviation, that is either with the value squared or in direct proportion to the ratio of the control deviation to the smallest capacitor section value (C/k)
- adjustable control range to reduce the number of control interventions in systems with a wide control range at high loads
- mains decompensation
- any control section can be set as fixed, that is as constantly connected or constantly disconnected
- Automatic Connection Detection
- any combination of measuring voltage and current
- automatic detection of connection and compensation systems’ nominal voltage on governor setup
Automatic Control Section Recognition- when switching it on, the governor automatically recognizes the sections’ power ratings
- It is possible to connect any combination of the control sections
- Specifying Section Value, Disabling Faulty Sections
- continuous specification of section value recognized in the control process
- continuous checking of control sections in the control process and in case of repeated failure detection, temporary disablement of the faulty section and possibly concurrent alarm actuation
- periodic recheck of the temporarily disabled sections in five days and on positive test results (for example when replacing a section’s burnt fuse link), enabling them again
Programmable Alarm- independent alarm warnings and actuation functions
- alarm can go off with undercurrent, overcurrent, voltage failure, undervoltage, overvoltage, THDI limit exceeded, THDU limit exceeded, CHL limit exceeded, out of power factor preset range, active power export, limit in number of section switching exceeded, section breakdown and temperature limit exceeded.
