I — INTRODUCTION

The Kepco FAW 150 Watt Series low profile h igh frequen cy switchin g power su pplies emp loy forward conversion and operat e with a 78% efficiency
with either a-c or d-c inpu t. A res istor a nd thyrist or so ft-star t circu it limits s tart- up sur ge. Surf ace m ount te chnol ogy pe rmit s efficient com pon ent l ayout
for minimum mounting space. Six models may be selected for outputs of 5, 12, 15, 24, 28, or 48V. “POWER OK” logic and a green “POWER OK” LED
are provided. A ste el cover ( Model CA 28) is av ailable as an opt ion. Outp ut voltag e may b e adjuste d with a trimmer accessibl e nea r the inpu t-output
terminal strip (R65, see Figure 4, View “A”). W hen the input is cut off, the output is maintained for 15 milliseconds minimum. If the pow er supply shu ts
down, it is then n ecess ary t o wai t 90 seco nd s minim um (120 V a-c inpu t) o r 120 seco nds mini mum (240V a- c in put) be fore reco nnect ing the a-c inp ut
