AE Techron 8102 Power Supply Amplifier Single Channel DC Coupled

Description

The AE Techron 8102 power supply amplifier features an advanced switch-mode design that results in low noise and distortion, and high power density. It is configured as a single-channel, DC-coupled, controlled voltage amplifier ideal for reactive loads. The 8102 can provide up to 16 Arms or 235 Vrms continuous output. It offers a continuous, full-power frequency bandwidth of DC to 5 kHz.

The 8102 also features an integrated switching power supply that reduces weight and allows the unit to fit a standard 2U rack space. The 8102 operates from single-phase, 120-volt AC mains (230 VAC versions available).

The 8102 amplifier is built and tested to the most stringent quality standards for long life and outstanding performance. The AE Techron brand is known throughout the world for its robust precision amplifiers as well as its product service and support.

Features

  • Up to 16 Arms and 235 Vrms continuous output
  • Full-power frequency bandwidth of DC – 5 kHz
  • Compact design; only 2U of rack space and 27 lbs
  • Switching power supply for reduced weight.
  • Installs easily into a standard 19-inch rack or stands alone for bench top operation
  • Built-in protection circuitry safely provides for sustained high-power output, with protection against input overloads, improper output connection (including shorts and improper loads), and excessive temperature, voltage or current.
  • Operates from single-phase, 120-volt AC mains, (230 VAC version available)

Front Panel Controls and Indicators

Fault Indicator

Red LEDs, flash when the amplifier output has stopped operating. Usually this means that the amplifier must be serviced

Thermal Indicator

Red LEDs, illuminate when the amplifier has shut down, or is very near shutting down, due to thermal stress or overload

Ready Indicator

Green LEDs, illuminate when the amplifier is initialized and ready to produce output

Input Signal Indicator

Green LEDs, illuminate when the amplifier’s input signal is above –40 dBu (8mVrms)

Output Signal Indicator, -20 dB

Green LEDs, illuminate when the amplifier’s output signal is within 20 dB of clipping

Output Signal Indicator, –10 dB

Green LEDs, illuminate when the amplifier’s output signal is within 10 dB of clipping

Clip Indicator

Red LEDs, illuminate when the amplifier’s output signal reaches the onset of audible clipping. The Clip Indicators also will illuminate during Thermal Level Control (TLC) limiting or when the input compressor/limiter is protecting the amplifier from input overload

Cooling Vents

Front-to-rear forced airflow

Power Indicator

Blue LED indicates AC power has been applied and is within the safe operating range of the power supply. The LED will flash when the AC line voltage is approximately 15% above or 25% below the nominal rated value

Data Indicator

Feature not implemented

Bridge Indicator

Illuminates when the amplifier is receiving AC power

Power Switch

Push-on / push-off switch

Back Panel Controls and Connectors

Power Cord Connector

Standard 15 amp IEC inlet. A circuit breaker located near the IEC power inlet protects the amplifier from excessive AC current draw

Reset Switch

Resets the circuit breaker that protects the power supply

Ventilation Grille

Air flow is front to back. Do not block the ventilation grilles

Input Panel

8100 Series Input Card includes two balanced 3-pin removable barrier connectors for signal input. The “Y” Input Switch can be used to daisy-chain the input signal to another amplifier. When this switch is set to ON, CH-1 input and CH-2 input are paralleled, reducing input impedance by 50%. Either CH-1 input or CH-2 input can be used when the “Y” Input switch is set to ON

Input Attenuator

One 21-position detented rotary attenuator, ranging from –100 dB to 0 dB gain

Output Connectors

One two-pole touch-proof terminal strip. Accepts up to 10 AWG terminal forks

Output Cover (not shown)

This covers the output connectors, protecting users from the connectors’ potentially high voltage. This cover is required for Class 2 wiring installations

Physical Characteristics

Required AC Mains (+15%, -25%)

120V/60Hz (230V/50Hz version available)

Height

3.5 inches (8.9 cm)

14.25 inches (36.2 cm)

Net Weight

27.0 lbs. (12.3 kgs)

Shipping Weight

32.0 lbs. (14.5 kgs)

Protection

Fault

The amplifier will light the Fault LED if the amplifier output stage stops operating. If this happens, contact AE TECHRON for servicing information

Low-Pass Filters

Gaussian-approximation ultrasonic filters prevent ultrasonic feedback and HF burnout of transducers. This type of filter preserves transient response better than a Butterworth filter

AC Under/Over Voltage Protection

If the AC line voltage drops below 25% or rises above 10% of the nominal operating voltage of the amplifier, the amplifier’s blue Power LED flashes. The LED will stop flashing and return to solid ON when the AC line voltage returns to safe operating levels

Circuit Breaker

A circuit breaker located near the IEC power inlet protects the amplifier from excessive AC current draw

Inrush Limiting

A soft-start circuit in the power supply minimizes the amplifier’s current draw during power-on
