The LVC623HF is a special extended frequency version of the LVC623 linear power amplifier. The LVC623HF will safely drive a wide range of loads from less than 1 ohm to an open circuit. The LVC623HF amplifier works well with continuous or pulse test signals.

The LVC623HF has two (2) separate channels than 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 ampers RMS or 16 volts RMS per channel into 2ohm load
> Frequency bandwidth of DC - 20kHz at full power, DC - 250kHz at reduced voltage
> Controlled Voltage operation
> 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 AC mains
> Installs easily into a standard 19-inch rack or stands alone for bench-top operation

OPTIONS – Factory installed
> DC Coupled (DC enabled) or AC coupled (DC Blocked)
> Fixed voltage gain (20, 44.5, 79.5) or Variable (0 – 20, 0-44.5, 0 – 79.5)

OPTIONS – User Configurable
> Channel configuration – two independent channels, two channels paralleled to Mono, two channels bridged to Mono
