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 8.0 amperes rms, or 16 volts rms, per channel into a 2 ohm load.
> Frequency bandwidth of DC to 20 kHz at full power, DC to 100kHz at reduced power.
> Controlled Voltage or Controlled Current operation
> User-adjustable voltage or current limiting.
> Remote force to standby mode by contact closure.
> External buffered monitoring of voltage and current output.
> Protection provided against, input overloads, improper output connection (including shorts and improper loads), excessive temperature, voltage or current, and under voltage conditions.
> Shipped ready to operate using single-phase, 120-volt, 20Amp or 230V, 10Amp AC mains.
> Installs easily into a standard 19 inch rack, or stands alone for bench top operations.

OPTIONS - User Configurable
> Variable voltage and current limiting
> DC Coupled (DC Enabled) or AC Coupled (DC Blocked)
>Controlled Voltage or Controlled Current Operation
> In Voltage mode - Fixed gain (20, 44.5, 79.5) or Variable (0 - 20, 0 - 44.5, 0 - 79.5)
> In Current mode - Fixed Trans-conductance (20) or Variable (0 - 20)
> Channel configuration - two independent channels, two channels paralleled to Mono, two channels bridged to Mono

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 choose between 2 channel, bridge mono and parallel mono operation.
