GT-AD series adjustable stabilized voltage constant current DC switching power supply / Adjustable DC power supply adopts the switching power supply technology of without Industrial Frequency transformer, so DC voltage regulator has the input function of AC/DC compatibility and wide input voltage range; DC voltage regulator adopts the advanced switching power supply control technology, components and aborative design, the DC voltage regulator has small volume, light weight, high efficiency, which ensures the stability and reliability of long-term full-load operation. DC voltage stabilizer has the perfect protection function. Build-in temperature control radiator fan, which not only effectively radiates but also effectively prolongs the lifetime of fan; Over-temperature automatic switch-off protection, output over-voltage, over-current and short-circuit protection. Soft starting when switch-on delays. DC voltage regulator and DC voltage stabilizer can avoid output voltage overshoot when switch-on. The DC voltage regulator/ DC voltage stabilizer is widely applied to electric power DC screen system, engineering control, communication, scientific research, charge of storage battery etc.
