※ Product Characteristic

Adopt switch mains with no power transformer technology, so input compatible with AC or DCfunction,and the input voltage range is wide. With elaborate design, small volume, light weight,high efficiency, use the advanced switching power supply control technology and components toensure the stability & reliability of the long-term operation at full capacity. It have the functionthat can directly connect masterless modular parallel current or masterless modular current-sharing(MMCS) control technique.


※ Voltage Stabilization & Constant Current

The power supply output voltage value (when the output current < output voltage of output constant current value ) and constant current value (when the output voltage < output current of output voltage value) can be continuously adjusted in the scope of their respective maximum. Adjustable constantcurrent output value bring convenience to many applications,  suach as debugging applications, rurn down the constant current value can effectively protect the load equipment.


※ Protection Function

Have perfect protection function. Built-in temperature-controlled cooling fan, so heat dissipation are effective; and the service life of fan are effectively extended. Overheating automatic shutdown protection; output over voltage, over current and short circuit protection. Soft start when stepup time delay, to avoid  instantaneous impact.


※ Environmental Conditions

Storage Temperature:(-20~50)℃;       Working Temperature:(-5~45)℃;

Relative Humidity :90%(40±2℃);       Atmospheric Pressure:(70~106)kPa;


※ Operating Principle 

AC or DC input voltage through "trap" circuit to the " rectifier filter” circuit, get high DC voltage (about 300 v). "Power Conversion" invert high DC voltage into 35 KHZ high frequency AC current;through the transformation of high-frequency transformer to get the desired output voltage, then through the high- frequency rectifier filter to get output voltage. Control circuit sample on the output voltage and output current. After closed loop feedback, the Pulse Width Modulation (PWM) signal control the “power conversion” circuit, so the output voltage or current are keep stable.


"Auxiliary Power Supply (APS)" is composed of switch power supply. Due to the Industrial Frequency Transformer is completely cancel, therefore the AC and DC input are compatible. Output voltage stabilization and constant current sample from the output side, and therefore high stability and reliability are available.

"Protection Circuit" provide temperature-controlled fans, output over-voltage over-current, overheating protection, short circuit protection, etc.
