Mar­ket’s widest XP Power prod­uct range

DEMM Engineering & Manufacturing - - PRODUCT WATCH - DE­TAILS, WWW.RS-ON­LINE.COM

RS COM­PO­NENTS says its new XP Power QSB Se­ries of DC- DC con­vert­ers means the global multi- chan­nel dis­trib­u­tor now has the broad­est range of power sup­plies from XP Power on the mar­ket. De­signed for ap­pli­ca­tions in­clud­ing sig­nal pro­cess­ing, tele­coms, net­work­ing and in­dus­trial sys­tems, the new QSB Se­ries de­liv­ers a sta­bilised out­put at a range of stan­dard volt­ages be­tween 3.3 V and 48 V, at power lev­els of 75 W to 600 W, says RS.

The QSB Se­ries ac­cepts a wide range of in­put volt­ages, typ­i­cally pro­vided from a bat­tery. In­put ranges for most mod­els are 2:1 or 4:1, in­clud­ing 18– 36 or 9– 36 VDC (24 V nom­i­nal) and 36–75 or 18–75 VDC (48 V nom­i­nal). How­ever, the 150 W QSB15048W mod­els of­fer a wider 8:1 in­put range, ac­cept­ing any­thing from 9 V to 75 V.

Power con­ver­sion ef­fi­ciency is high: typ­i­cally be­tween 86 per­cent and 93 per­cent de­pend­ing on model. High power den­si­ties of up to 123.0 W/ in3 are achieved. Mod­ules can be con­nected in par­al­lel for higher power re­quire­ments.

All QSB Se­ries power con­vert­ers pro­vide 1500 VDC iso­la­tion, with iso­la­tion re­sis­tance of 107 Ω or 109 Ω and iso­la­tion ca­pac­i­tance rang­ing from 100 pF to 4000 pF. All pro­vide re­mote on/off func­tions, and all ex­cept QSB15048W mod­els in­clude re­mote sense, com­pen­sat­ing up to 10 per­cent of nom­i­nal out­put volt­age.

QSB con­vert­ers are avail­able in base­plate cooled pack­ages with in­dus­try stan­dard foot­prints — in­clud­ing half brick and full brick for­mats. They can op­er­ate over a wide tem­per­a­ture range from – 40°C to +100°C. Over-volt­age, over- cur­rent and over-tem­per­a­ture pro­tec­tion are pro­vided.

Each unit car­ries a three-year war­ranty.
