Control low noise DC power supply

  • Max Voltage: 18V to 650V
  • Max Current: 0.1mA to 5mA
  • Max Power: 36W to 108W
  • Great operability

RG series is no longer available as we stopped the production and sales of this model in August 2020. Meanwhile, we support. The R4G series is available as the successor model and more information on the series can be found here.

R4G series

Superior operability and sophisticated design

The RG series is a high-performance linear DC power supply designed for precise and stable operation. The RGE series is a cost-effective version that maintains the same operability and performance as the RG series, with simplified functions optimized for basic experiments.
A wide lineup of 13 models, ranging from 18 V to 650 V, allows you to select the ideal model for your requirements. Compact and lightweight, these power supplies are suitable for research and development, burn-in testing, system integration, and educational applications.

Functions

function01
function02

The RG series is renowned for its user-centric design that ensures intuitive operation. Every detail, including the visibility of the meter, the layout of the terminals, and the feel of the output control knob, has been engineered for usability.
The output control is tuned for a natural response—neither too sensitive nor too slow—allowing for precise and stress-free adjustments.

Remote Control Connector J2 (RG series only)

*These functions are not available on the RGE series.

Remote sensing

Compensates for voltage drops caused by contact resistance or the resistance (R) of the output wire, ensuring stable voltage at the load point (up to a maximum of 0.5 V compensation).

Remote sensing

* Common external control and output are still connected even when the AC power supply is turned off. Please be careful when using external control.
