Low-cost com­pact con­vert­ers with high iso­la­tion

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

MORNSUN has a new LDE/LHE range of AC/DC Con­vert­ers in 3W – 25W.

The se­lec­tion of­fers up­graded tech­no­log­i­cal and process im­prove­ments whilst mak­ing ad­vances in over­all per­for­mance and size along with IEC62368, UL62368 prod­uct com­pli­ance and EN62368 stan­dards ( pend­ing), ), says the man­u­fac­turer.

Prod­uct ad­van­tages are – im­proved per­for­mance with wide op­er­at­ing tem­per­a­ture ranges; the LDE se­ries of­fers - 40 ˚ to 70 ˚ and the LHE se­ries - 40 ˚ to 85 ˚. Cou­pled with 4KVAC iso­la­tion that de­liv­ers im­proved re­li­a­bil­ity and sys­tem safety, whilst EMC: EMI per­for­mance meets CISPR32/EN55032 CLASS B.

Low cost and com­pact size makes the LDE/LHE range with in­te­grated in­ter­nal com­po­nents al­low for a 20 per­cent size re­duc­tion, with greater con­sis­tency, re­li­a­bil­ity and per­for­mance, while fur­ther im­prove­ments make for a lower cost and more com­pet­i­tive de­vice. Due to up­graded au­to­ma­tion tech­nolo­gies the new LDE/LHE range boasts high re­li­a­bil­ity – hav­ing in ex­cess of 300Khrs MTB – and a com­plete suite of pro­tec­tions, out­put short cir­cuit (OSC), out­put over- cur­rent (OCP) and out­put over- volt­age (OVP), which sig­nif­i­cantly re­duces the fail­ure rate of the con­verter it­self and en­hances safety per­for­mance for back- end power mod­ules and the load in ad­verse work­ing con­di­tions.

LDExx-20Bxx range of­fers 3W, 5W, 6W, 10W, 15W and 20W mod­ules and the LHExx-20Bxx range of­fers 5W, 10W, 15W, 20W and 25W de­vices. De­sign Ref­er­ence: t yp­i­cal ap­pli­ca­tion cir­cuit

Ap­pli­ca­tions: Can be widely used in any ap­pli­ca­tion re­quir­ing a re­li­able cost ef­fec­tive power source in­clud­ing LED, street light­ing con­trol, grid power, in­stru­men­ta­tion, in­dus­trial con­trol, com­mu­ni­ca­tion and civil ap­pli­ca­tions.

Fea­tures in­clude Uni­ver­sal In­put: 85 – 264VAC/100 - 370VDC op­er­at­ing tem­per­a­ture range: - 40 ˚ to +70 ˚ ( LDE se­ries), - 40 ˚ to 85 ˚ ( LHE se­ries) high iso­la­tion volt­age 4KVAC low rip­ple and noise: 50mV TYP. Out­put short cir­cuit, over­cur­rent, over- volt­age pro­tec­tion plas­tic case, meets UL94V- 0 EMI per­for­mance meets CISPR32/EN55032 CLASS B Meets IEC62368, UL62368, EN62368 stan­dards ( pend­ing).
