AV-HLZA1 TEST LOAD / ADAPTER

 

 

An AV-HLZA1 test load / adapter is provided with the AVOZ-E3-B. When shipped from 

the factory, it is configured with five 2W resistors in parallel installed between the OUT 

and GROUND lines, for a total effective resistance of 1Ω (10W). Please note that it is 

not capable of dissipating the maximum average power that the AVOZ-E3-B can deliver

(100 W).

The user may use the provided resistance as-is, or disconnect one end to allow a diode

load to be added in series with it, or remove the resistors entirely and connect to a 

different load as needed.

The AV-HLZA1 test load / adapter may be plugged directly into the rear-panel OUT 

connector, or it may be plugged into the end of the AV-HLZ1-100 cable. Both
