DiscontinuedR4GE/R3GE series

Compact & High Resolution DC Power Supply

  • Max Voltage: 6V to 650V
  • Max Current: 0.1A to 10A
  • Max Power: 12W to 180W
  • High Speed Response

TK series is no longer available as we have stopped the production and sales 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 Series Regulator System

R4GE series are series regulator system 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 convertor adapted newly. Not only Overvoltage protection but also Overcurrent protection is included as standard equipment. They are applicable to wide range from experiment to automation line.

Features and Benefits

Voltage and/or Current displayed 4 digits indicator (R4GE)
Voltage or Current is indicated with 4 digits despite of its compact size. It has been possible to control output in more detailed unit as [0.1 mA] and [1 mV] than ever.
Standard Equipment of Various Function
Overvoltage Protection, Overcurrent Protection and Key Lock are included as standard equipment.
Ultra low Ripple and High Speed Response
High Speed Response with ultra-low ripple and low noise by the series regulator system.
Silent Naturally-cooling System (108 W Model and Smaller)
Operation sound is silent as no cooling fan. It is best fit for usage that its operation sound hinders measuring like as test of fan motor. And it is the safety design so as not to expose the heatsink from the case.

Applications

  • Various Research and Development
  • As the Power Supply for System
  • For Aging
  • School Training Aid

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.

Series Operation

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.

Parallel Operation

Split Operation

+ and - output are possible.
