ePower is specially designed for harsh environment, can work under the temperature of -40 ℃~+85 ℃, with protection rating up to IP65. ePower is reliable for application and installation under harsh environment. ePower’s IO which has function of open circuit and short circuit diagnosis can be flexibly configured according to customers’ requirements. ePower can be used either as power module or IO module. Compared with relay control, ePower is a highly integrated power management module. Also it has a far more lifespan than traditional relay. Each port has protection function themselves, such as open circuit and short circuit protection. Total current output can reach up to 90 A at the same time.
