LRS series 250w AC to DC single output switching power supply

LRS-250 series is a 250W single-output enclosed type power supply with 30mm of low profile design.

Adopting the range 110/220 input selected by a switch, the entire series provides an output voltage line of 5V,12V,15V,24V,36V, and 48V.

Delivering an extremely low no-load power consumption(less than 0.5W), it allows the end system to easily meet the worldwide energy requirement.

LRS-250 series serves as a high-price-to-performance power supply solution for various industrial applications.
