LVC623 Amplifier Specifications
APPLICATION
The LVC 623 is a general purpose, medium voltage, high continuous current, linear power amplifier. It works best when driving loads of 1 - 4ohms. The LVC 623 works well with continuous test signals. The LVC 623 has two (2) separate channels that can be operated independently or combined for greater maximum voltage or current. In bridge-mono mode the available output voltage doubles. In parallel-mono mode the amplifier operates with double the output current.

FEATURES
> Output of 13.0 amperes rms, or 26 volts rms, per channel into a 2 ohm load.
> Frequency bandwidth of DC to 20 kHz at full power.
> Option of controlled voltage, or controlled current operation, modes changed via a jumper.
> User-adjustable voltage or current limiting.
> Remote switching to standby mode by contact closure.
> External monitoring of voltage and current output.
> Equipped with circuitry to protect the amplifier from input overloads, improper output connection (including shorts and improper loads), excessive temperature, voltage or current.
> Shipped ready to operate using single-phase, 120-volt AC mains.
> Installs easily into a standard 19 inch rack, or stands alone for bench top operations.
INDICATORS AND CONTROLS
> Front panel LEDs indicate signal presence and output overload.
> A pushbutton power “On/Off” located on the front panel.
> Two gain controls on the front panel for controlled voltage applications.
> Two circuit breaker resets on the back panel.
> A back panel slide switch to lift signal ground from chassis ground.
> A back panel slide switch to choose between 2 channel, bridge mono and parallel mono operation.
OUTPUT POWER
