1 PRESENTATION
The Quanser AMPAQ is a high-bandwidth, linear current amplifier. There two AMPAQ models: the two-channel
AMPAQ-L2, shown in Figure 1.1a, and the four-channel AMPAQ-L4, shown in Figure 1.1b. The AMPAQ L2/L4 has
the following features:
• Power amplifier capable of supplying up to 2.5 A.
• Current sensing capability.
• 10 kHz bandwidth in current mode.
• Emergency stop capability.

2 COMPONENTS
The components on the front and back panels of the AMPAQ are depicted in Figure 2.1. Each component on
the AMPAQ has an identification number that corresponds to a short description given in Table 2.1. The pin out
information for the RCA and CPC connectors are shown in Figure 2.2.
ID Name Description Electrical
range
1System Power LED Indicates whether the AMPAQ L2/L4 is powered on.
2E-Stop 6-pin mini-DIN
connector
The Emergency Stop Switch connects to the E-Stop
socket. If the E-Stop is not connected, the AMPAQ L2/L4
is enabled by default. If the E-Stop is connected, then the
state of the amplifier depends on the E-Stop.
3Enabled LED The light corresponding to each linear current amplifier
channel turns on whenever that amplifier is enabled.
4Amplifier Command RCA
connector
Use this channel to apply the analog voltage command to
be amplified from the data acquisition device.
±10 V
5Current Sense RCA con-
nector
Use this channel to measure the current output of the am-
plifier channel.
±10 V
6To Load CPC connector Connects the amplifier output to the DC motors in the plant.
This signal is the control command to motors which has
been amplifier by the unit. The Table 2.2 outlines the pin
description for this connector.

Table 3.1: AMPAQ L2/L4 specifications
Caution: Precaution must be taken during the connection of this equipment to the AC outlet to make sure
the grounding (earthing) is in place and the ground wire is not disconnected.
Caution: Avoid covering the fan during operation to prevent premature thermal shutdown of the amplifier.
Caution: Do not position the equipment so that it is difficult to operate the on/off switch.
Caution: The AMPAQ L2/L4 devices are made to be used with Quanser designed experiment kits that have
particular actuators. Use caution if the AMPAQ L2/L4 is being used with your own actuator. Any
load to be used with the AMPAQ L2/L4 should have a minimum inductance of 0.1 mH.
AMPAQ L2/L4 User Manual v 1.1

Caution: Do not use the cables provided with the AMPAQ L2/L4 to wire it to experiments that use a different
amplifier module, such as the Quanser Rotary (SRV02) or Linear (IP02) products, as this will result
in burning the motors. The AMPAQ L2/L4 can be used with such experiments only if plant specific
cables are available.
4 FUSE INSTALLATION
The AMPAQ L2/L4 has a single 3AG, 250V, 5A fuse that protect the amplifier from overcurrent through the main
power connector.
Caution: Make sure the power to the amplifier is disconnected before changing the fuse!
Follow this procedure to install or replace the fuses in the AMPAQ:
1. The fuse holder is located at the rear of the unit, as shown in Figure 2.1.
2. Make sure the amplifier power cable is disconnected.
3. Remove the fuse holder. To do this, push and twist the knob counter-clockwise (CCW) and pull the fuse holder
out as illustrated in Figure 4.1.
Figure 4.1: Remove fuse holders
4. As shown in Figure 4.2, remove the old fuse from the holder and insert the new one.
Figure 4.2: Replacing fuse in the fuse holder
5. Install the fuse holders back into the amplifier. Push the fuse holder back into panel and twist the knob clock-
wise until secure.
Caution: Installing the wrong fuse rating may result in damage to your amplifier.
6. Connect the power cable to the back of the amplifier.

5 CABLE NOMENCLATURE
Table 5.1 provides a description of the standard cables used with the AMPAQ L2/L4.
Cable Type Description
(a) Motor cable
5-pin-DIN to CPC
male cable
This cable connects the amplifier to the load.
To apply the amplified signal to the actuator,
connect this from the To Load socket on the
AMPAQ L2/L4 to the system actuator.
(b) 2xRCA to 2xRCA cable
2xRCA to 2xRCA
cable
This cable is used to connect the amplifier to
the data acquisition (DAQ) device. To apply
the reference signal to the amplifier, connect
an analog output channel on the DAQ device
to the Amplifier Command socket on the AM-
PAQ L2/L4. To measure the current in the
load, connect an analog input channel on the
DAQ device to the Current Sense socket on
the AMPAQ L2/L4.
(c) Emergency Stop Switch
Emergency Stop
Switch (E-Stop)
Enables/disables the amplifier. Connect this
cable to the AMPAQ E-Stop connecctor. The
amplifier is deactivated when the knob is in
the pressed DOWN position. It is enabled
when the knob is in the upright, released posi-
tion. If the E-Stop cable is not connected, the
amplifier is always enabled.

6 TROUBLESHOOTING
Follow the steps given below based on your issue with the AMPAQ L2/L4.
Amplifier does not power up.
• Make sure the power cable is firmly connected to the power connector on the back of the amplifier
• Verify that the fuse is not burnt. If the fuse is burnt, see Section 4 for furst rating and replacement information.
Motor/load is not being driven.
• Verify that the fuse is not burnt. If the fuse is burnt, see Section 4 for furst rating and replacement information.
• If the AMPAQ L2/L4 is being used with a Quanser system, verify that all the connections illustrated in the User
Manual for that Quanser product have been made correctly.
• If the Emergency stop switch is connected to the amplifier, make sure the red button is in the upper position to
enable the amplifier. The amplifier cannot be enabled when the button is in the lower position. The Enabled
LED on each channel should be lit. Twist to release the red button into the enabled position.
