FOR POWER DEVICE AND INVERTER TESTING

REH is a high-power and high-voltage power supply designed with the accumulated know-how by Matsusada Precision, a leading manufacturer of high-voltage programmable power supplies.
The REH’s compact design makes it ideal for production lines, and test bench.

MAIN APPLICATIONS

FEATURES AND BENEFITS

  • One of the world's smallest sizes in its class of 1200 V 15 kW
  • Ultra low profile and space-saving design with 2U (3.5 inches (89 mm)), 3U (5.2 inches (133 mm)) height
  • Well suited for solar cell characteristic evaluation and solar inverter evaluation.
    The REH is also ideal for testing inverters and electrical components used in electric vehicles.
  • Extensive safety design from high voltage experience and technology.
  • More than 30 kW output is possible by using our CO-MS series digital controller to combine REH power supply.

Options

-LF

Floating ground (withstanding voltage of 50 Vdc)
Used when measuring minimal current in the load. All equipment that connects to the Remote Control Connector (TB1) must be on the floating ground in case this feature is intended to be used.
(Cannot be used for the purpose of floating REH series.)

-LGob

Optical Interface port
This option changes the standard interfaces to a built-in optical interface port. By combining this option with an adapter for optical connection (sold separately), communication between the control device and the power supply can be controlled in an isolated state. Be sure to select this option when using the product in the following environments.

  • -LGob: Optical interface port + optical cable 2 meters
  • -LGob(Fc5): Optical interface port + optical cable 5 meters
  • -LGob(Fc10): Optical interface port + optical cable 10 meters
  • -LGob(Fc20): Optical interface port + optical cable 20 meters
  • -LGob(Fc40): Optical interface port + optical cable 40 meters

Select the optional optical interface board (-LGob) when using this DC power supply under the following conditions.

  • Noisy environments such as factories (example: when motors or coils are used near loads or power sources).
  • If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
  • When there is a possibility of arcing or output short-circuit.

The optical communication adapter at the control side should be purchased separately.For details, click here.
