8300 SERIES OPERATOR’S MANUAL – SECTION 1
1 Introduction
Congratulations on your purchase of an 8300 se-
ries digital power amplier. 8300 series ampliers
are 200Vp, low-noise, DC-to-50 kHz switch-mode
ampliers. They are fast enough for DC automo-
tive dropout testing and capable of AC voltages
required for ISO 61000 and Aviation testing. Plus,
they have low enough noise and distortion speci-
cations to be the reference power source in power
quality measurements.
1.1 Features
Wide Bandwidth and Flexible
The 8300 series amplier is capable of reproduc-
ing AC, DC and AC+DC waveforms into loads from
a dead short to high impedance. It can be used to
simulate a battery at 13.5 VDC or be an AC source
with a L-N potential of up to 140 VAC. Rated cur-
rent, for a given voltage, is available for all wave-
form types (AC, DC or AC+DC) at frequencies
from DC to 50 kHz. Voltages from 0 to 140 VRMS
are available with no changes in conguration.
Reuses Energy from Reactive Loads
The 8300 series excels when it comes to driv-
ing reactive loads. As frequencies increase, the
eective-impedance of the load becomes a much
larger part of the total load to be driven (especially
with inductive loads like coils).
However, when driving reactive loads, the 8300
series amplier is capable of receiving, reprocess-
ing and returning to the load up to 5X its rated
power. The result is a system capable of up to 50
kVA output while drawing less than 10 kW of AC
mains power!
1.2 Conguration Options
A key to everyday product usability is quick and
easy product (re)configuration. The 8300 series
amplifier provides all key configuration controls on
the back panel of the unit. Configuration options
available include:
• Gain: Fixed or variable gain (0 to 40)
• Current Limit: From 5% to rated limit (to
protect fragile DUTs or where specified in the
Standard)
• DC Control: DC enabled or DC blocked and
DC Servo (for driving transformer-coupled
loads, coils)
• Input: Balanced and/or unbalanced
• Mode: Voltage source or current source
• Output Impedance: Variable from 0 to 1 ohm
(Voltage mode)
• Sense: Correction to voltage drops to the load

WARNING
Figure 2.1 – Cable Lift Rings
2 Amplier Unpacking and
Installation
8300 series ampliers are precision instruments
that can be dangerous if not handled properly. Le-
thal voltages are present in both the AC input sup-
ply and the output of the amplier. For this reason,
safety should be your primary concern when you
setup and operate this amplier.
2.1 Safety First
Throughout this manual special emphasis is
placed on good safety practices. The following
graphics are used to highlight certain topics that
require extra precaution.
2.2 Unpacking
Your amplier will be delivered to the ship-to ad-
dress enclosed in a wooden crate and transported
on a special, shock-absorbing pallet. With the
addition of packaging, the amplier can weigh up
to 700 pounds (318 kg). To avoid serious injury
and/or product damage, use a heavy-duty lift or
other suitable equipment to unpack and move the
product to its place of installation.
To uncrate the product, remove the top and one
side of the crate, then use a lift or other suitable
equipment to glide the amplier from the crate and
o the pallet. Cable lift rings are installed at the
amplier top corners to facilitate product removal
(see Figure 2.1).
The amplier has been tested and inspected for
damage before leaving the factory. Carefully un-
pack and inspect the product for damage. Please
note any damage for future reference and
notify the shipping company immediately if
damage is found. Also, please save the shipping
crate and pallet as evidence of damage and/or for
returning the amplier for repair.
2.3 Check Contents
In addition to the 8300 series amplier, your ship-
ment should include the following:
1. Pagoda top
2. Quick Start Guide
3. 8300 series Operation Manual on USB drive
2.4 8300 Series Placement
8300 series ampliers are mounted on wheels to
allow rolling on a at, smooth surface. To avoid
possible tipping, always push the amplier from
the front and avoid rough or pitted surfaces.
Locate your amplier near a three-phase power
source. Allow enough clearance at the front and

This section details the wiring and startup pro-
cedures for an 8300 series amplier operating in
Controlled-Voltage mode (factory default). Before
connecting the amplier inputs and outputs, make
sure the AC power is disconnected.
3.1 Testing Before Controlled-Current
Operation
IMPORTANT: If your application requires Con-
trolled Current operation, the 8300 series amplier
rst should be wired and tested in Controlled-
Voltage mode to verify that the amplier and input
signal are operating correctly. Once proper opera-
tion is conrmed, refer to the Applications sec-
tion of this manual for instructions on conguring
and operating your amplier in Controlled-Current
mode.
