Two phase switching power supply is an electrical power source which is used to produce power for demanding loads in high efficiency and in adjustable voltage and current values. Two phase switch- made power supplies are produced for current range from 5 to 14 A. When more power is required, switching power supplies can be paralleled. Special features of two phase switch-made power supplies : - High efficiency -Low loss power - power boost by parallel connection - Short circuit protection: 1) Manual reset: In case of short-circuit or overload, the output current is interrupted. In order to restart the output it is necessary to switch-off the input circuit for about 1 minute. 2) Hiccup mode: In case of short-circuit or overloading, the output current is interrupted. The device tries again to re-establish output voltage and normal condition about every 2 second till the problem is cleared. 3)Continuous output mode: In case of short –circuit or overload, the output current is kept at high values with near zero voltage. In case of short circuit the current can reaches up to 3 times the rated current at 60ºc. This protection mode is used to meet the requirements of demanding loads such as motors, solenoid valves, lamps, PLC with highly capacitive input circuits and other loads with marked transient overload behavior.
