Finally, we are almost there. Our first product – a joint development result of cooperation between IACS and RTOS.BE – is about to be commercialized. The Energy2Switch is a DC switch board with 2 channels rated up to 50V and 40A. Continuous power is limited at 1500W per channel, which boils down to 40A @ 37.5V e.g. It is capable of PWM at 100Hz (and for certain applications even 250Hz) up to the maximum specified amperage and voltage: If a duty cycle of 100% would deliver 40A, a duty cycle of 50% will deliver an average of about 20A. Of course, the higher the PWM frequency, the higher the switch losses and the higher the heat generation in the on-board mosfets.

It can be used for general prototyping, dimming of DC lamps and lights, DC heater control, simple motor control, battery charging, and anything you can think off to control higher DC power devices. We use it for energy harvester prototyping.

One connects the board channel inputs to 3V (or 5V) outputs of the microcontroller of your choice in order to control (switch or PWM) the individual channels. It is – for example – compatible with Arduino (5V) and most ARM MCUs (3V). The board itself needs at least 12V DC to reliably switch or PWM the high loads.

IACS is compiling the complete datasheet.
