Analog interface The PCR-M Series is a small-size AC power supply with the ease of a variable auto transformer or an automatic voltage regulator (AVR) and the usefulness of a multifunctional AC power supply. As the PWM inverter method is adopted for the power unit, the PCR-M Series is much smaller and lighter than the predecessors while enabling high-quality and highly-efficient (about 70%) operation. This power supply comes with measurement functions, memory function, protection functions and various communication interface options, and it is even possible to provide DC power. When you incorporate an optional analog interface board (EXO4-PCR-M), the PCR-M Series can also be used as a booster for arbitrary signal generator. You can control the PCR-M Series through the standard RS-232C interface, the optional GPIB interface, or the optional USB interface. And by using the control software (Easy Controller for PCR-M) which comes with the PCR-M Series, you can easily set the parameters of the PCR-M Series and log the output measured values.
