Harmonic filter power factor compensator (PFC)
400 V, 100 - 500 kvar | ERAF series
Enerlux
ERAF series is composed of:
* Metal CABINET equipped with cooling fins, made of
sturdy pressed sheet metal treated with a phosphating
process to protect against corrosion and then painted
with epoxy powders, colour RAL 7035.
* Main three-pole fast-tripping DISCONNECTING
SWITCH interlocked with the door.
* Sets of three FUSES type NH00 curve gG with a high
breaking capacity, sized to protect the capacitor banks.
Three-pole contactors, sized for connecting the single
batteries. Their peculiarity lies in the fact that the insertion contactors of the limiting resistors close in advance
of the main contactors to limit the current peak at the
insertion of the residual currents. The coils are 110Vac
50Hz (other voltages on request).
* Dielectrically oversized CAPACITORS of the "dry" type
PRT.
* Internal connecting CABLES are flameproof type
N07VK.
* Copper BARS size 30x5 mm
* ELECTRONIC REGULATOR for automatic battery
connection and cosφ control.
* Forced VENTILATION SYSTEM made with special,
thermostat-operated fans installed on the top of the
cabinet.
* Blocking REACTORS made with a core of top-grade
magnetic plate with low-loss oriented grain.
Tuning frequency: 189Hz(p=7%);
on request: 134Hz(p=14%) -210Hz(p=5.67%).
Harmonic distortion in current permitted in continuous
operation: 30%In at 250 Hz and 15% In at 350Hz.
Linearity: 2In.
Max harmonic distortion in voltage permitted in
network (THD%)=5%.
