The DELTA DTA4848R0 T/C is a precision power supply inverter engineered for industrial power conversion applications requiring reliable DC voltage regulation across wide input ranges. This VFD power supply delivers exceptional stability and efficiency for critical systems where precise voltage control and minimal ripple are essential. With a robust operating temperature range of -40°C to 85°C and precise output voltage regulation from 0.990V to 1.010V at full load, the DTA4848R0 T/C ensures consistent performance in harsh industrial environments while maintaining compatibility with a broad range of DC input voltages from 36V to 75V.
The DTA4848R0 T/C maintains exceptional output voltage stability across varying loads and temperatures. At full load (Io.max) and 25°C ambient temperature, the output voltage ranges from 0.990V to 1.010V DC, ensuring precise regulation within a 0.1% tolerance. This tight control is critical for sensitive electronic systems requiring stable power supplies, particularly in applications where voltage fluctuations could disrupt operation.
This power supply exhibits rapid transient response capabilities, with a positive step change in output current from 50% to 75% of maximum current generating only 350-500 mV voltage change. Similarly, negative step changes produce minimal voltage fluctuations (-500 to -350 mV). The 0.1A/µs current slew rate ensures smooth transitions during load changes, making it suitable for applications with dynamic power demands.
The DTA4848R0 T/C features optimized input power consumption across different operating conditions. At 48V input, the no-load current is 80-110-140 mA, while the off-converter input current is as low as 10-18-26 mA. These low power consumption characteristics minimize energy waste during idle periods and ensure efficient operation in power-sensitive industrial systems.
Engineered for extreme environmental conditions, the DTA4848R0 T/C operates reliably in ambient temperatures ranging from -40°C to 85°C. This wide temperature range ensures consistent performance in both cold and hot industrial environments, such as outdoor installations or high-temperature manufacturing facilities. The storage temperature range extends to -55°C to 125°C, supporting deployment in extreme conditions.
The DELTADTA4848R0 T/C is an industrial Power Supply. Selection should be based on the documented characteristics and the requirements of the intended application.
