AE Techron 7224 Overview
Single-phase, 2U, industrial amplifier
- Field-selectable controlled-voltage or controlled-current operation
- Can be switched between rail supply modes and voltages to optimize for various load impedances
- Protection circuits guard against over/under voltage, over current, over temperature, and circulating ground currents
The AE Techron 7224 amplifier is a 900-VA, DC-enabled unit that provides exceptional versatility and value. It features a DC to 400 kHz small-signal bandwidth and offers a wide range of field-configurable options. In continuous operation, a 7224 can provide 900 watts RMS of output power. If more current or power is needed, up to four amplifiers can be combined in series or parallel and operate as a single system.
The 7224 can be configured by the user for highvoltage/low-current, medium voltage and current, or low-voltage/high-current applications. It provides very low noise and fast slew rates, and can safely drive a wide range of resistive, inductive loads.
The 7224 is typically used to simulate ripple, noise, drop-outs, surges and ground as required by a variety of EMC standards for DC powered electronics like FMC1278, DO-160, and MIL STD 461. It can also be used as a gradient amplifier for very small bore, high-gain MRI and NMR systems.

Installation
The 7224 amplifiers are packaged in a rugged powder-coated aluminum chassis. This chassis is 2U (rack units) tall, and has rack “ears” on each side of the front panel for mounting to a standard EIA (Electronic Industries Association) rack. Use standard rack mounting hardware to mount the amplifier. Use nylon washers if you wish to protect the powder-coat finish on the front of the amplifier.
Optionally, the amplifier can be placed on a bench top; please keep in mind that the protective powder-coating can be scratched when placed on other equipment or on a bench top, especially when there is dirt present. To protect the finish, a set of rubber feet is included in the toolkit that can be installed on the bottom of the amplifier.
Allow ample space on the sides and especially the back of the amplifier for heated air to escape. The amplifier should be mounted in a rack that is adequately ventilated and not sealed. Likewise, the front of the amplifier should be unobstructed to allow cool air to enter the amplifier.
Connecting the Load
Before connecting the amplifier, make sure the AC power cord is unplugged.
This section describes output wiring to the load when using the default amplifier configuration: Single (or Master) amplifier operated in Controlled Voltage mode. The 7224 amplifier also can be field-adjusted for operation in Controlled Current mode or for operation as a Slave amplifier in a multi-amplifier system. These alternate configu - rations may require special output wiring and/or additional components.
If your application requires Controlled Current and/ or Slave operation, change the default settings on the main board before connecting the amplifier.
Connection to the output of the amplifier is to a 3-position terminal strip with #8 screws. Wires terminated with #8 ring terminals, tinned wires up to 10GA in size, or bus bars with 0.18 in. (4.6 mm) holes are recommended when connecting to the output terminals. Connect the load across the terminals marked “OUTPUT” (positive) and “COM” (negative/ground). The third terminal, “CHAS- SIS GROUND” can be connected to an external ground point such as the rack chassis.
Connecting the Load
Always use the appropriate wire size and insula- tion for the maximum current and voltage expected at the output. Never connect the output of the amplifier to any other model amplifier, power sup- ply, signal source, or other inappropriate load; fire can result.
NOTE: The 7224 amplifier comes with a factory-in- stalled 2.7-ohm, 2W, 5%, metal-oxide resistor con- necting the terminals marked “COM and “CHAS- SIS GROUND” (see Figure 2.3) . This resistor should NOT be removed. WARNING: Removing this resistor can cause dangerous output and/ or damage to the load.
