R4GE/R3GE series is no longer available as we have stopped production and sales of this model in September 2021. Meanwhile, we support. R4G/R4GN series is available as the successor model, and more information on the series can be found here.

R4G/R4GN series

Realized Ultra-low Noise with Linear Regulator System

R4GE series are linear regulator systems with high accuracy and ultra-low noise DC power supplies so that enabled setting and reading out more fine output with a 4 digits indicator and a high-resolution D/A and A/D converter adapted newly. Not only Overvoltage protection but also Overcurrent protection is included as standard equipment. They are applicable to a wide range from experiments to automation lines.

Features and Benefits

Voltage and/or Current displayed 4 digits indicator (R4GE): Voltage or Current is indicated with 4 digits despite its compact size. It has been possible to control output in the more detailed units as [0.1 mA] and [1 mV] than ever.

Standard Equipment of Various Function: Overvoltage Protection, Overcurrent Protection, and Key Lock is included as standard equipment.

Ultra low Ripple and High Speed Response: High-Speed Response with ultra-low ripple and low noise by the linear regulator system.

Silent Naturally-cooling System (108 W Model and Smaller): Operation sound is silent as no cooling fan. It is the best fit for usage that its operation sound hinders measuring like a test of a fan motor. And it is the safety design so as not to expose the heatsink from the case.

Operations

Examples of Applied Operation

R4GE and R3GE series can be enhanced in its output voltage or current by hooking the same type of units in series or parallel.

Series Operation

Sum total of output voltage is 250 V.

Accordingly, ones of exceeding 250 V its output voltage can not operate in series. Output current is one of the smallest power supply.

Parallel Operation

Make all setting voltage the same value. Output current is sum total of one of each unit. Then, make OVP level of all power supplies the maximum to prevent damage.

Split Operation

+ and - output are possible.
