Seamless Switching Between Source and Sink

Traditional power supply and load have short transitions and inconsistencies in the middle of positive and negative current switching. The IT-M3400 integrates bidirectional power supply and regenerative e-load in one, which is capable of achieving high-speed and seamless switching between source and sink. A fast and seamless transfer between source and sink effectively avoids voltage or current overshoot. The IT-M3400 is widely used in batteries, battery packaging, battery protection boards and other energy storage equipment testing.

CC & CV Priority

IT-M3400 continues to support CC / CV priority function, help customers solve a variety of severe problems in long-term testing. For test that require high-speed voltage, users can select the CV priority mode to obtain a faster voltage climb speed; or choose CC priority mode, output current without overshoot, used to test DUT with constant current operating characteristics. This function is widely used in power supply transient simulation and characterization test applications, such as lasers, integrated circuits, charge and discharge, automotive electronics.

Modular Design, Flexible Combination

The flexible modular design makes it simple for IT-M3400 to stack directly, no need to purchase any accessories. The user may use IT-E154 optional rack mount kit to install one unit or more units into 19” rack case.

Multi-Channel Independent Control, Maximum 256 Channels

IT-M3400 provides flexible multi-channel function, the users can build-up multi-channel source-sink system, each unit will show the channel number on the front panel. PC only need to connect with one unit to control and program all the units independently by GUI software. IT-M3400 support maximum 16*16 channels, each 37U rack can integrate 64 units which is 64 channels. It supports parallel connection for high power testing demands, to provide high flexibility and functionality for users.

High Energy Regeneration Efficiency

IT-M3400 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.

~6307 kWh can be deducted from your electricity and cooling bill using 1pc IT-M3400 (800W) for 1 year.

Battery Simulation Function

battery matrix. The user can set the battery by choosing ITECH optional professional BSS2000 battery simulation software, by setting common battery parameters to quickly establish the battery characteristic curve, they can also set the initial capacity of the battery, to verify the characteristics of the product in different states of the battery.
