Your source for AC Current Measurement products plus BELUK power factor

control relays and Specialty Contactors designed for Power Factor compensation.

The Beluk family of products consist of the BLR series of Power Factor Controllers,

KSR Capacitor Protection Relay and EMM 5 Power Analyzer.

BLR controllers include the BLR-CA, BLR-CB, BLR-CC, BLR-CM and the latest in the series,

the BLR-CX. The following is a brief description of each of the instruments plus a link to our

download page where PDF files of bulletins and installation instructions for most instruments

may be found. Extra detail is included on this page for the BLR-CX along with a specific link

to obtain the complete instruction manual for the unit.

Additional products from Beluk are accessories to the power factor correction function such as software and data loggers for the BLR series plus static contactors.

When developing the BLR series of power factor controllers, the Beluk engineerinig

staff attached great importance to simplicity of installation and operation . With the

new design of the products, each instrument automatically sets up after a few simple

switch settings by the installer. It is no longer necessary to select the starting current

(C/k value) or a fixed switching program.

The relays start working as soon as they have been correctly connected and they will

always select the most appropriate capacitor step size. The recognition of the values

of capacitor steps is achieved without unnecessary test switchings and instead is based on values obtained during the daily operating routine of reactive load compensation.

Common Features on - CA, - CB, - CC, and - CM models

► 4-quadrant measurement of reactive and constant supervision of inductive/capacitive load

► measurement and supervision of each step of kvar output during switching process

► adjustment of current transformer ratio for control purposes is not required.

(On BLR-CM, input of the CT ratio is required for the indication of values measured).

► adjustment of target cos phi in the range 0.70 (lag) - 1 - 0.90 (lead)

► adjustable switching time

► manual switching may be selected

► no-volt release with power interruption greater than 35 ms.

► 90 second lockout time following power failure and subsequent power restoration.

► optical (LED) indication of each individual stage

► failure alarm if target cos j is not achieved (after completion of 75 switching cycles)

► failure alarm if relay detects there is a risk of overloading capacitors due to excessive

harmonic current

► adjustable switching time delay

► plug in terminal blocks

The BLR-CX Power Factor Controller

The BLR-CX controller has incorporated all of the features of the - CA, - CB and - CC models plus added new capabilities to make this new unit an even greater value than its predecessors! There only two options offered for the BLR-CX controller as all other items are now standard: the options are the addition of a temperature controlled fan relay and the second PF target (option - L) and a measurement option (option - M) that provides a display of the electrical system parameters - full descriptions for options are included below and in a PDF instruction manual available on request.

BLR-CX Standard Features

► 4-quadrant measurement of reactive and constant supervision of inductive / capacitive load

► measurement and supervision of each step of kvar output during switching process

► adjustment of transformer ratios for control purposes is not required on standard models.

(On BLR-CX-xx-M or -L-M input of the CT & PT ratios are required for indication of values measured).

► adjustment of target cos phi in the range of 0.70 (lag) to 1.0 to 0.90 (lead)

► adjustable switching time from 5 to 1200 seconds

► manual switching may be selected whenever required

► no-volt release with power interruption greater than 35 ms.

► 90 second lockout time following power failure and subsequent power restoration.

► optical (LED) indication of each individual stage

► display of measured power factor

► failure alarm if target cos j is not achieved (after completion of 75 switching cycles)

► instrument may be connected in either a three phase system or a single phase

► available in 4, 6, 8 or 12 step models

► asymmetrical switching time delays are user programmable

► automatic alarm indication of failed steps

► automatic and “1111” (first in, last out - last in, first out) switching programs are user selectable

The upper photograph shows the front of BLR-CX or BLR-CX-L. In addition to the standard features listed above, the “L” option provides a rear mounted temperature sensor and internal measuring circuits + output relay that may be used to control a fan when a preset temperature has been sensed. The preset temperature set points are 30° C, 35° C, 40° C & 45° C. Fan control option “L” is a simple and inexpensive way to monitor and control the cabinet temperature allowing any heated capacitors to cool down to their correct operating levels. The “L” option also includes a second power factor target that is typically used for night tariff operation.
