Emotron U1T-220/400-DC/LT Brand Introduction Emotron U1T-220/400-DC/LT is U1T series DC input variable frequency drive developed by Emotron for heavy-duty motor speed regulation applications. It specializes in converting 220VDC input into 400V three-phase AC output to drive asynchronous motors, serving as compact metal enclosed inverter assembly for renewable energy, DC bus power supply and rugged industrial motor control loops.

DC Input Variable Frequency Drive is the core unit of Emotron U1T-220/400-DC/LT. DC Input Variable Frequency Drive adopts robust metal cabinet housing, 220VDC power input, three-phase 400VAC motor output, low temperature (LT) version for cold ambient environments. DC Input Variable Frequency Drive supports adjustable output frequency, built-in motor overload, overvoltage, undervoltage and short-circuit protection functions, equipped with local keypad and display for parameter setup and fault diagnosis. It uses advanced PWM modulation to deliver stable torque output even under fluctuating DC supply.

Emotron U1T-220/400-DC/LT provides stable Drive for workshop field DC powered motor speed control. Drive supports continuous heavy load operation and wide DC input fluctuation tolerance. Drive features high starting torque and vector control performance for fan, pump and conveyor loads. Drive adopts reinforced low-temperature hardware design to guarantee reliable startup and running in low ambient temperature sites.

Emotron U1T-220/400-DC/LT features reliable Transmission for DC power source and three-phase induction motor devices. Transmission communicates via DC power cable and three-phase motor power wiring. Transmission is fully compatible with Emotron motor control and industrial automation systems. Transmission converts DC power into variable frequency AC power to regulate motor rotation speed and realize energy saving and process closed-loop control.

Emotron U1T-220/400-DC/LT is widely used in solar and battery power driven equipment, off-grid pumping systems, mobile machinery, marine auxiliary drives and legacy DC bus motor control system renovation. With mature Emotron heavy-duty drive technology, this inverter works within extended low temperature range and has strong anti-vibration and EMC anti-interference performance. It provides full lifecycle technical support including wiring, parameter commissioning and after-sales maintenance, serving global users as a trusted U1T series 220VDC input 400V output low-temperature VFD solution.
