8302 OPERATOR’S MANUAL – SECTION 6

20

To begin testing, input a square wave with a fre

-

quency of 100 Hz to 1 kHz, or a squared pulse at a 
low level (typically 0.25 to 2.0 volts). A limited-rise-
time, repetitive pulse of low duty cycle is preferred. 

Observe the output current through a current 
monitor or current probe. Look for clean transition 
edges. The presence of ringing or rounding on the 

transition edges indicates compensation problems. 
(See 

Figure 6.5

.)

If a change in compensation is necessary, please 

contact 

AE Techron Technical Support

 for as-

sistance. 

DO NOT

 operate your amplifier in Con

-

trolled Current mode without proper compensation.

6.3  Driving Reactive Loads

Like all switching amplifiers, 8302 amplifiers are 
able to reuse the energy returned from reactive 
loads. Unlike purely resistive loads, loads with 
some reactance (either capacitive or inductive) will 
store energy during part of a cycle, and then re

-

lease some of this energy back later. This energy 
is transferred back to the load through the ampli

-

fier’s power supply.  This allow the amplifier to 
deliver continuous apparent power that is up to five 
times the rated power of the amplifier when driving 

reactive loads.

8302 Multi-amp Systems

The 8302 amplifier may be used with one other 
8302 amplifier in either a Parallel or a Push/Pull 
(Series) configuration. The Parallel configuration 
will approximately double the continuous current 
output to 120 Arms, while the Push/Pull configura

-

tion will approximately double the voltage avail

-

able from a single 8302 amplifier to 280 Vrms (see 

Figure 6.6

).

While it is possible to operate a multi-amp system 
in either Controlled Voltage or Controlled Current 
modes of operation, multi-amp operation in Con

Tech Support 

for assistance with configuring a 

multi-amp system for Controlled Current operation.

For routine, Controlled-Voltage applications, 
Parallel and Push/Pull amplifier systems can be 
configured using standard 8302 amplifiers and the 
following accessory available from AE Techron:

8000 Series Multiamp Kit (part # 69-8005462).
