PST21A Datasheet, PDF (5/13 Pages) Power System Technology – AC-DC 1200W Conduction cooled

Remote Senses (+S -S)
Waveforms
This feature enables compensa�on of voltage drop across the connec-
tor contacts and the load lines. Remote Sense, max 0,5V per line com-
pensa�on (If local sense, connect locally S+ to OUT+ and S- to OUT- of
the corresponding output). Senses are not included on Microboard.
output noise - PST21A-5300-48150-550-3V375
Output type
V1, V2
PowerGood & LED
Total drop
< 0.5V
Posi�ve line drop
< 0.25V
Collector isolated optocoupled signal referred to RTN, closed when all
outputs voltages are OK. Led is also available for each output.
Auxiliary bias voltage (+5VAUX)
Auxiliary supply limited to 1mA. Referred to RTN
Paralleling signal (PR)
Parallel only iden�cal outputs (voltage and power). Outputs in parallel
will current share when their corresponding PR are connected together.
When outputs are coming from different boards, RTN have to be con-
nected together.
