and visibility. These facilities include: voltage input; current limit input, current
limit indicator and display, compensation mode, gain setting, output range,
current limitation, system stop and output and sense connectors.
For convenience, voltage and current control and monitoring interfaces have
been duplicated. BNC connectors are provided for general purpose connec-
tion to signal generators and an integrated control D-type connector for direct
connection to the Teseq NSG 5000 series. The output terminals are duplicated
with 6 mm socket type connectors for push-in termination as supplied with the
Teseq Automotive test systems.
Power dissipation is always a consideration with amplifiers. To avoid excessive
heat the PA 5840 range includes a range selection switch on the front panel
to enable the amplifier to deliver more power continuously when simulating a
12 V system the low voltage range is selected which can provide a reduction
in power dissipation which allows continuous operation for longer under high
load conditions.
The amplifier inputs are over voltage protected and outputs short circuit pro-
tected. Overtemperature protection is monitored on the internal heat sink and
transformer.
There are three selectable ranges for compensation / bandwidth for the
PA 5840. Bandwidths are high, allowing fast slew rates as required by numerous
standards.
The current limit is programmable from 10 to 100% of the output current capa-
bility.
