The LI24 is a new range of slim power supplies from Mornsun. They feature an AC input range of between 85 and 264 V a.c. and DC input range of 120 to 370 V d.c., with output voltages of 5 V d.c. at 4 A, 12 V d.c. at 2 A and 24 V d.c. at 1 A. The 22,5 mm wide modules have input/output isolation of 3 kV with ripple voltage of 50 mV. These devices feature short circuit protection and are suitable for operating temperatures of -10°C to +70°C.
Also newly launched is a family of DIN rail models designated the PWB/VRB and WRB/URB series. These are offered with output power of 3, 6, 10, 15, 20, 30 and 40 W. Input voltages of 12 V d.c. (9–18 V), 24 V d.c. (18–36 V) and 48 V d.c (36–72 V) with outputs of 5 V, 12 V and 24 V d.c. are offered. These modules feature low ripple and noise and boast MTBFs of 100 000 hours.
