KEISOKU GIKEN Ene-phant series regenerative DC power supply (bidirectional) 50kW

Space-saving contributes to the ground area

For the 50kW single unit, the width has been reduced by 150mm and the depth by 100mm compared to the previous model, and the installation area ratio has been reduced by approximately 0.31m2. Both the area ratio and the volume ratio contribute to space saving of about 30%, and flexible installation is possible.

Regeneration efficiency of 90% or more, the highest level in the industry

Achieves high efficiency of 90% or more (at rated load). Furthermore, if the rated power is 15% or more, a regenerative efficiency of 80% or more is achieved. Highly efficient regeneration is possible over a wide range of load power.

Expandable up to 5 units of 250 kW! Series-parallel combination enables high voltage and large current

If it is the same model, you can connect up to 2 units in series like batteries (excluding 1500V models) and up to 5 units in parallel connection. Depending on the stage of evaluation and testing, a flexible configuration can be realized using a master/slave unit, from capacity expansion by combining multiple units to individual operation of multiple units.

high speed operation

High-speed current response speed of 10msec or less and seamless power running (drive: power supply) and regeneration (absorption: load) switching are realized. Therefore, there is no overshoot or undershoot of the current, so you can use it safely without giving unexpected stress to the test piece.

Compliant with grid connection regulations

Equipped with system monitoring and protection functions that comply with the grid connection protection device certification test, it has the same monitoring and protection functions as general commercial power conditioners, and can circulate energy safely and without waste. can. Various system monitoring functions can be set to arbitrary values.

Oscilloscope-like operability

Adopts oscilloscope button layout and operability. The function pasted on the button image on the LCD screen is switched, enabling intuitive operation.

Regenerative power noise CISPR Class A compliant

Regenerative power noise complies with Class A. It has low noise so that there is no influence such as operation failure on other devices due to regenerative power noise.

Body protection function

As a protection function of the electronic load device, 8 types of protection circuits are implemented to support safe test operation.

control interface

LAN (Ethernet) and PLC interface are common and standard equipment. Remote control including automation from the host PC is possible.

Emergency stop button

Equipped with an emergency stop button, which is essential in the car electronics industry. During operation, the power line gate is blocked (forcibly opened by the conductor). It is guarded to prevent malfunction, and external control (Di input) is also possible.
