Product Category : Power Factor Meters
Neutronics Manufacturing Company offers Microcontroller Automatic Power Factor Control Relay. Neutronics Manufacturing Company manufactures varied instruments used in the industrial process control industries. The Microcontroller Automatic Power Factor Control Relay is specially designed to control the power factor of an installation by giving signals to switch capacitors on and of in a FIFO/FILO manner accordingly and reliably.
Salient features of Microcontroller Automatic Power Factor Control Relay are:
Field Proven Design.
Compact DIN Standard flush mounting 96 x 96 mm width with 70 mm depth.
Low cost efficient A P F C Relay.
Built in all Factory Set Parameter.
Built in Digital Timer for fast operation to ensure capacitor safety.
Available in 4, 6, 8 Stages
FIFO / Binary sequence available on request
Auto detection for low current and external wrong connection indication
Digital P F meter for a accurate measurement
Built in low current cut off at 1%
The Microcontroller Automatic Power Factor Control Relay is used to compensate the Power Factor of Major on / off loads such as compressor, Utility supply transformer and work as a regular power factor control relay. It is available for three phases as well as for single phase application. The single phase relay is used for unbalance load where as three - single phase systems are used in star connections. The relay is available in FIFO/ Binary sequence. Unless &otherwise specified, FIFO sequence is supplied. The controller is factory programmed & designed to provide the best possible Power Factor under system conditions.

| Low Current |
Factory set at 1 % Display reads t.01 when the Current is too low. |
| Wrong |
Three voltage wires and two wires from the CT on the main incomer connect the APFCR in the Electrical system. The APPFCR switches off all Stages and displays reads t.02 to warn the Operator. This condition persittill correct connections are made. |
| Connections |
Reads t.02 to warn the Operator. This condition persittill correct connections are made. |
| Meter |
Three digit Digital Meter: Range : 0.000 lag-1.000-0.000 lead. |
| Limits |
The capacitor are switch on sequentially wheneve rthe power factor Drop to or below 0.99 lag.The capacitors are switch off sequencially when the power factor goes above 0.99 lead. |
| Timing |
Timing between the stages on or off is 6-8 seconds. A capacitor once switch off is not allowed on for 60 seconds to allow it to discharge fully. |
