Specifications:
The SE-1500 series is a 1500W single output power supply with various models including SE-1500-5, SE-1500-12, SE-1500-15, SE-1500-24, SE-1500-27, and SE-1500-48. It operates with a DC voltage of 5V to 48V and a rated current range from 31.3A to 300A. The power supply features an output voltage adjustment range of 3.3V to 5.5V and a line and load regulation of 2.0% and 0.5% respectively. The setup and rise time is 150ms, with a hold-up time of 26ms at full load.

Input Specifications:
The input voltage range is 180 to 264VAC or 254 to 370VDC, with a frequency range of 47 to 63Hz. The typical efficiency is 81%, and the inrush current is 17.5A at 230VAC. Leakage current is less than 3.5mA at 240VAC.

Protection Features:
The power supply includes protections for overload (105-125% rated output power), over voltage, and over temperature. It shuts down output voltage and requires re-powering to recover. The over temperature protection automatically recovers after cooling down.

Safety and Standards:
The SE-1500 series complies with UL60950-1 safety standards and has a safety withstand voltage of 3KVAC between input and output. Isolation resistance is 100M Ohms at 500VDC.

Environmental Conditions:
Operating temperature ranges from -20 to +70°C, with a working humidity of 20 to 90% RH non-condensing. Storage conditions are -40 to +85°C and 10 to 95% RH.

Mechanical and Additional Features:
The dimensions are 278 x 177.8 x 63.5mm, and it weighs 3.3Kg. The power supply includes a built-in DC ball bearing fan for cooling, a DC OK signal output, remote ON-OFF control, and a remote sense function. It is UL/CUL approved and comes with a 2-year warranty.

Functionality:
The DC_OK signal is a TTL level signal indicating the power supply status. The remote control function allows turning the PSU on and off via electrical or dry contact. The remote sense function minimizes noise pick-up by connecting sensing lines to the load terminals.
