K841 (150-375 KVAR)
K841B (375-1875 KVAR)

Avtron inductive/reactive load banks (KVAR) are typically used in combination with resistive load banks (KW) to test a generator or power source at 0.8 power factor (lagging). The reactive load bank should be sized at 75% of the resistive load bank KW rating to achieve a 0.8 power factor. The resistive and reactive load banks are connected and operated in parallel.

Models such as the K841 and K841B range from 50 - 1500 KVAR. They are designed for indoor or outdoor permanent installations and come complete with remote operator control panels (19" rack mount or NEMA enclosed).

Avtron inductive/reactive load banks feature non-saturating single phase and three phase iron core load reactors.

Note: Other models with different KVAR and Voltage ratings are available on special order.

Control Power: Typical power required for control circuit operation is 120VAC, 1phase, 60 Hz. If 120VAC, 1phase, 60Hz is not available, a variety of single phase control transformers can be provided as an option.

Blower Power: Blower power is typically provided by an outside source. Selected load banks are available with blower power derived from the power source under test.

Metering: A variety of analog and digital metering packages are available for various models for display of volts, amps, frequency, KW, KVAR, power factor, KVA, including data logging and acquisition software (consult the factory.)

Skid Mounted Resistive/Reactive Load Banks

Standard Models

LPS (1500-2000KW; 1125-1500KVAR)

The Avtron LPS Load Bank System provides an economical and convenient means for high capacity resistive and reactive load testing of AC power systems. Many specifications and local codes demand that such testing be performed at less than unity power factor, typically 0.8 p.f. To achieve a 0.8 power factor, the LPS combines resistive load (KW) with reactive load (KVAR). This combination provides a true test of the actual generator or UPS nameplate rating (KVA) and simulates a "real world" load. The Avtron LPS System is integrated on a rugged structural skid with provisions for overhead, four point lifting.

LCV (3000/4000/5000 KW; 2250/3000/3750 KVAR )
K980

The Avtron LCV load bank is designed to provide high capacity resistive and reactive loading of AC power systems such as diesel generator sets, turbines, or Uninterruptible Power Supplies (UPS). Many specifications and local codes demand that such testing by performed at less than unity power factor, typically 0.8 p.f. lagging. To achieve a 0.8 power factor, the LCV combines resistive load (KW) with reactive load (KVAR). This combination provides a true test of the actual generator or UPS nameplate rating (KVA) and simulates a "real world" load.

The load bank consists of a rugged ISO style 20 foot container housing the resistive and reactive components, blowers, associated controls and interconnections. The unit has a load capacity ratings of 3750-6250 KVA at 480 VAC, 3 phase, 60 Hz. (Other voltages and frequencies are available - consult factory.) The unit is PLC controlled with a convenient hand-held remote controller. Laptop computer control with data logging is also available as an option.

Model: LCV *	Capacity	Minimum Load Step Resolution	Load	Blower	Approx. Size	Approx. Weight (lbs.)
	3750KVA	25KW 18.75KVAR	480VAC; 3phase	460VAC; 3phase; 60Hz	239"L, 96"W, 108"H	28,600
