should be connected to Vi– to enable the output (active low
logic, fail safe).
IMX15 and IMY15 models with -9 (not for new designs) have a
limited temperature range. Standard models with suffix -8 are
rated up to TA = 85 °C; see table Temperature specifications.

Option R
pin i left open-circuit:
Magnetic feedback from the output for closer regulation of the
output voltage Vo1 of double output units (standard for single
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
If the inhibit function is not used, the inhibit pin should be
connected to Vi–.
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

Accessories
Supports are available for chassis mounting (CMBIMX15,
HZZ00626) and DIN-rail mounting (DMBIMX15, HZZ00625).
They exhibit the connectors and allow for placing different
external components. For details see our Mounting Supports
