• Manufacturer Part Number: 40IMX15-03-8RG
• Manufacturer: POWER ONE

Option -9 versus -8
IMX15 and IMY15 models with -9 (not for new designs) have a
limited temperature range. As a standard, these models with
suffix -8 are rated up to T
specifications).
The -8 models will provide the output power in the derating
curve specified in the fig. below with free air convection
cooling.

Maximum allowed output power versus ambient temperature.
Option R
Magnetic feedback from the output for closer regulation of the
output voltage V
output units and -0503- models). It enables the adjustment of
the output voltages via the R-input (pin 17) on the secondary
side by an external resistor or an external voltage source. This
function is described in Auxiliary Functions.
Furthermore, the output 1 is accurately regulated like the
single output models. The Trim input (pin 3) is not connected.

Option i: Inhibit
Excludes the shut-down function.
The output(s) of the converter may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied to the inhibit
pin. No output voltage overshoot will occur, when the converter
is turned on. If the inhibit function is not required, the inhibit pin
should be connected to Vi – to enable the output (active low
logic, fail safe).

If the inhibit function is not used, the inhibit pin should be
