Description:
The AFH programmable AC Power Source provides cost effective instrument grade AC Power. The isolated AC output can be controlled manually using the front panel operator keypad, or remotely via GPIB/IEEE.448, RS232C or APG (Analog Programming)ⁱ⁾ for fully automated computer controlled applications.

All models incorporate PWM technology for efficient power delivery, and DSP or 16 Bit methodology to provide precise high speed measurement of output.

The AFH is provided with front panel display(s), built-in self diagnostics and protection including Overvoltage, Undervoltage, Overcurrent, Over Power, Short Circuit, Overtermperature and Fan Failure.

The 375VA and 800VA models are Rack Mount Ready and can be ordered with enclosure for table top applications. The 1,500VA • 3,000VA models

are table top ready, and can be ordered with optional Rack Mount Kit. The 6,000VA and 9,000VA models are provided in a rack enclosures with caster wheels.
