Our “CV-S” series constant Voltage mode power sources are stable and easy-to-use power sources designed with linear circuitry.

1. Basic Version

Our standard basic “CV-S” models offer a 0-130 V rms. (0-260 V and 0-65 V output voltage ranges are available at request) and frequency range of 30 Hz to 20K Hz at the above output ranges. They have a built-in oscillator and equipped with both “Local” and “Remote” control methods. In “Local” mode, the user can use the 10-turn locking pot and push-wheel switch to control the amplitude and the output frequency. In “Remote” mode, the user can use a 0-10V DC control volts to control the output amplitude.

2. RS232 and GPIB Controlled Versions

In the “Remote” mode, we offer “RS232” and “GPIB” control methods to replace the “0-10V DC” control method if specified. (Please add “/RS232” or “/GPIB” at the end of the part number when ordered.)

3. Closed-loop Feedback and External Synchronization Functions

In both “Local” and “Remote” modes, our constant voltage sources have been equipped with Closed-loop Feedback function and External Synchronization functions.

4. “CV-A” Version

In some applications, the users just require constant voltage mode power amplifiers instead of power sources. (The users will provide the input signal from their own function generators.) We call such a version as and “CV-A” version. They are simple and easy to use power amplifiers, with 10-turn locking pot on front panel as an alternative amplitude control method. All the other controls, including output amplitude, frequency, phase and so on will be on the external signal generator. As a result, the “CV-A” version is cheaper than the “CV-S” version.

The output waveform of our constant voltage sources is defaulted as sine wave. Square wave output is available at request.

Constant voltage sources and amplifiers provide a steady output voltage independent from the load and input power line with variations. Our customers use our constant sources and amplifiers to generate magnetic fields and test, qualify products such as lighting products, transformers, meters, and so on.
