IT-M3600 Regeneratives Stromversorgungssystem

Das regenerative StromversorgungssystemIT-M3600 integriert zwei Instrumente in einem, nämlich eine bidirektionaleStromversorgung und eine regenerative elektronische Last. Wenn es als Lastverwendet wird, kann seine Energierückgewinnungsfunktion die aufgenommeneGleichstromleistung in Wechselstrom umwandeln und in das Netz zurückführen.Wenn es als Stromversorgung verwendet wird, kann es auch als bidirektionaleGleichstromversorgung mit großer Reichweite eingesetzt werden. Das IT-M3600kombiniert die Vorteile beider Geräte gut miteinander, und seine geringe Größevon nur 1 HE im halben Rack hilft Ihnen zudem, Platz, Zeit und Kosten zusparen. Mit seiner hochpräzisen Ausgabe und Messung eignet sich der IT-M3600für mehrere Testfelder wie z.B. Mehrmodulbatterien,Mehrkanal-Stromversorgungen, Mikro-Inverter und Halbleitergeräte.

One button switch between source and load

IT-M3600 integrates two devices in a small size of 1U Half-rack, which not only be operated as a high performance bidirectional DC power supply; but also be operated as a regenerative e-load. Simulate various load characteristics and feedback power to grid without pollution, multi-functions in one. Users do not need to use software and any terminal equipment to switch operation mode, one button switching can greatly save time and space.

1U Half-rack

IT-M3600 is only 1U Half-rack, but the power output is up to 800W. Besides high power density, it also has high resolution, high accuracy and high stability, etc. The output voltage is up to 600V and the output current is up to 30A. All series containing 12 models with ultra-wide range output design, can be widely used in various Applications.


Seamless switching between source and load

Different from the traditional power supply and load, the switch between positive and negative current, it will have transient jumps and discontinuities. IT-M3600 integrate bidirectional power supply and regenerative load in one unit. When work under source mode, it supports high speed switch between source and sink mode, such seamless switch between positive and negative current is fast, continuous, and seamless, so as to avoid the current or voltage overshoot during the test. This can be widely used to various tests related to storage unit such as battery, battery packaging, battery protection board etc.


High energy regeneration efficiency

IT-M3600 series is regenerative when working in sink under source mode, also regenerative working under load mode. The max regeneration efficiency is up to 90%, which can save the cost for both electricity and cooling system, achieving low noise testing environment.


Battery simulation function

IT-M3600 support to simulate max. 99 cells in series andparallel connection. The users can quickly select battery matrixby setting battery voltage, capacity, resistance, SOC from thefront panel.
ITECH provides optional BSS2000 battery simulation software,users can self-define the battery curve by setting commonparameters, also can set battery initial capacity to verify theDUT characteristics under different battery status. Meanwhile,BSS2000 supports to import matlab battery matrix or CSV. filewith battery charging and discharging curve, so as to simulatereal battery charge and discharge characteristics.


Battery Test Function

IT-M3600 series Regenerative Power System, which integrates power supply and regenerative electronic load into one unit, and adjustableoutput impedance design, can simulate the charging and discharging characteristics of the battery, and perform other testing, too. It can beused not only test the multiple single cells, but also comprehensive test the battery packages. It can also perform the battery setting and dataprocessing in various test conditions and plot the test figure.


Multi-channel independent control,maximum 256 channels

IT-M3600 Series is provided with independent multi-channel design.The channel sequence will be displayed when it combines to be a multi-channel power and electronic load system.The user can control each unit independently by PC software when connecting the communication interface of one unit with PC. Each channel can be operated separately. IT-M3600 Series supports maximum 16*16 channels. One 37U rack case contains 64 channels. The user may test DUT with different power ranges by parallel connection, making tests more flexible and device usage more efficient.


Multiple Protection function

IT-M3600 series have comprehensive protection functions, it can also provide OCP, UCP, OVP, OTP, OPP, UCP and grid fault protection,fault storage function, power-off protection function and sense sensing abnormal protection. With unique foldback protection functiondesigning, it is used to turn off the output as soon as the power supply is switched by CV/ CC for protect the DUT which are sensitive tovoltage overshoot and current overshoot. As it can automatic detect of power grid status, the product will be shut down when the power gridis suddenly disconnected, which can achieve reliable grid connection and islanding protection. The pre-charging function can prevent the DCload current from overshooting. Users can choose the anti-reverse connection module to achieve the anti-reverse protection function andeffectively suppress the battery surge.

Multiple operation modes

IT-M3600 provide CC/CV/CP/CR four basic operation modes based on power system mode.
IT-M3600 also provide CC+CR/CV+CR/CV+CC/CC+CV+CP+CR four compound operation modes based on load mode, which can adapt to thetest requirments of various occasions.


CC&CV priority

IT-M3600 series continue the notion of CC&CV priority, help user to solve several critical problems with long-term testing.It can make the testeasier especially for the applications like hign speed power supply or no overshooting current. when need the testing occasions of voltagehigh speed, users can choose CV priority mode to get fast voltage rising time. Users can also choose CC priority mode to output noovershooting current,it's good for test DUT under CC working condition.This is used in various applications field such as laser test, IC test,charge and discharge test, military and transient simulation of power supply in automative electronics and so on.


Parallel function

IT-M3600 supports paralleling multiple units of same model to achieve higher current and power. Users may parallel units in master-slaveoperation according to different required current values. Up to 16 units can be in parallel.
IT-M3600 can still have the same high-speed measurement capability as single unit after running in parallel with multiple units.
