For Power Device and Inverter Testing

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

Features and Benefits

  • One of the world's smallest size in its class of 1200 V 15 kW
  • Ultra low profile and space-saving design with 2U (3.5-inch/89 mm), 3U (5.24-inch/133 mm) height
  • Well suited for solar cell characteristic evaluation and power conditioner (Solar inverter) evaluation. The REH is also ideal for testing inverters and electrical components used in hybrid and electric cars.
  • 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.

Main Applications

  • Power Device
  • Inverter
  • Power Conditioner (Solar inverter)
  • Solar Cell

Options

-LF: Floating ground (withstanding voltage of 50 Vdc)

Used when measuring minimal current in load. All equipments that connect to Remote Control Connector (TB1) must be on floating ground in case this feature is intended to use.

(Cannot be used for the purpose of floating REH series.)

-LGob: Optical Interface Board

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

Insulation control is made with optical communication. As a perfect insulation is made by optical fiber it is able to forestall miss operation as a transient phenomenon caused by a surge, dielectric thunder or external noise, etc.

Optical Interface Board
(B) CO-opt cable
As of models with -LGob option, a two meter cable is provided in each model. If you need a long cable, please consult with our sales staff.
Select the optional optical interface board (-LGob) when using this DC power supply under the following conditions.
  • Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
  • Using with high voltage floating (more than 250 V).
  • Installation distance of 2 meters or more between the DC power supply and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).
If you use plural REHs in optical communication, please use them according to the following ways.
  • Connecting all REHs which has optical I/F board serially
  • Connecting all REHs serially: The first TB is optical I/F board type, and all REH after the 2nd are standard I/F board type

-LLc: Low-capacity capacitor for solar cell

-LOcp: Overcurrent protection

Output is cut off at a set value. (One-turn volume on front panel)

-LPfc*: Power factor correction circuit

[Available for greater than 6.4 kW models. Height for models greater than 10 kW is 6.97" (177 mm) instead of 5.24" (133 mm)]

-L(115V): 115 Vac ± 10% input, Input current: 20 A typ. (for 1.1 kW model)

-L(220V): 220 Vac ± 10% input, Input current: 9.9 A typ. (for 1.1 kW model)

-L(400V)*: 400 Vac input coming soon

-L(3m)/-L(5m)/-L(7m): Changing the length of high voltage output shielded cable

Please choose the length of an electrical cable in 3, 5, or 7 meters. Please contact nearby sales office if you want a length of more than 7 meters.

* These options cannot be chosen together.

How to Order

When ordering, add Option No. to Model No. in alphabetical order followed by the input voltage and the cable length.
