The Avtron Model LPH150S Load Bank is a portable, selfcontained AC resistive model designed for indoor use.
The Avtron LPH150S Load Bank gives users the freedom of a high capacity load in a compact 
package. The LPH150S is ideal for routine testing and maintenance of AC power sources such 
as stand-by emergency generators and UPS systems. This load bank provides a full 150 KW at 
480 VAC or 240 VAC, 3 Phase, 60 Hz.
This versatile load bank weighs approx. 220 lbs. [99 kg] and is approx. half the weight and size 
of traditional load banks of similar capacity. The load bank features horizontal air discharge to 
provide a low profile design. Quick-connect load terminals and simple operation allow the load 
bank to be set up and operated by a single technician, saving valuable time in the field.
The load bank controls and cooling fans are powered by any standard 120 VAC, single phase 
wall outlet with detachable line cord provided. An integral control panel includes the necessary 
controls and status indicators. 
The entire control of the LPH150S is via the Intelligent Hand-Held Terminal (IHT). The IHT  
provides all control and metering functions along with network capability to control multiple 
load banks.
