Analog To PWM - PWM157

Analog To PWM - PWM157

The PWM157 is an analog to pulse width modulator that is factory configured for a wide range of voltage (100mV to 100Vdc) current (1mA to 1Adc) signals.

The output frequency is factory set between 10Hz and 3kHz. As the input signal rises the output pulse width will change from the minimum specified to the maximum on time total period.

The unit can be factory set for reverse action if required. Final calibration is trimmed using the front accessible ZERO and SPAN 15-turn trim adjustments.

The output pulse amplitude is adjustable via the 15-turn reference front potentiometer, which allows exact pulse voltage levels to be set.

Output is indicated by an LED which provides clear indication of module function and PWM percentage.

Power supply variations from 240Vac down to 8Vdc all providing isolation of 2kVrms/2.5kVdc
