PRTM series

High Power DC Power Supply

  • Max Voltage: 1500V
  • Max Current: 4080A
  • Max Power: 120kW
  • Space saving

High power up to 120kW in a slim rack

PRTM series, a high capacity DC power supply comes with PRT series models in one rack, offering at least three times the output range more than the previous ones.

The DC power supply employs a total current display and also provides elaborated protections as standard equipment. Accordingly, it provides strong supports especially for customers' research and development requiring large current and high power.

PRTM series, Only 19.3-inch wide

Refer to PRT series as for base model details. PRT series

Features and Benefits

  • Wide voltage output function is provided. PRTM series is available with voltage/current outputs three times wider than the previous models within the rated output power range.
  • CV/CC priority setting function enables the overshoot suppression by setting the voltage/current rise sequence when the output is turned ON.
  • Internal resistance variation function enables simple simulation of rechargeable batteries, photovoltaic cells, fuel cells, etc.
  • Switching function of sink current/sink current prevention provides application support for maintaining voltage as well as requiring high-speed response. Models with maximum output voltage 500 V or less
  • Low-noise switching system is best suited for research and development activities.

Main Applications

Electric Vehicles (EV), Hybrid Vehicles (HEV) and Automotive Equipment
Evaluation testing of inverters, compressors, DC/DC converters, DC motors, relays, harnesses, etc.
EV connect to PRTM series
Secondary Batteries
Charge/discharge testing of secondary batteries such as lithium-ion, nickel-metal hydride and lead-acid batteries
Photovoltaic Cells
Evaluation testing of power conditioners, junction boxes, etc.
Various types of electrolysis and electrolytic synthesis such as hydrogen generation

The series is also applied for evaluation testing of electrical parts and electrical products such as fuses, connectors and lamps.

* These options cannot be selected simultaneously.

-LBr: Protective breaker

One protective breaker is installed for each rack.

-LBr option is not available for PRTM80V3570A105kW and PRTM80V4080A120kW.

-LCa: CAN interface board* Coming soon

Output control and operation status monitoring of these devices can be performed using CAN communications.

-LCk: CC-Link interface board* Coming soon

Controlled by CC-Link from a CC-Link master device such as a PLC. Compatible with CC-Link ver1.10, and operates as a CC-Link device station. Two stations are occupied per unit, and a maximum of 32 units can be controlled.

(Please refer to materials of the CC-Link Partner Association for detailed specifications of CC-Link.)

-LEb: Eye bolts

Four eyebolts mounted to the top side allow you to move the product using cranes.

-LGob: Optical Interface Board *

  • -LGob: Optical Interface Board + optical cable 2 m

  • -LGob(Fc10): Optical Interface Board + optical cable 10 m
  • -LGob(Fc20): Optical Interface Board + optical cable 20 m
  • -LGob(Fc40): Optical Interface Board + optical cable 40 m

Isolation control is performed by optical communication. As complete isolation is performed by means of optical fiber, this enables advance prevention of erroneous operation comprising transient phenomena resulting from surges, inductive lightning, external noise, etc.

Please purchase a control-side optical communications adapter separately.
As for USB – optical converter adapter, USB – OPT by Matsusada Precision is compatible.


The option is available for PRT500V/100A and PRT850V/53A.
Rated input for three phase 380 Vac to 440 Vac
