Notes:
1. The specified maximum capacitive load is for each output.
2. Load regulation is measured over a range of 15% I
OUT
to 100% I
OUT
.
3. When measuring output ripple & noise, it is recommended that an external capacitor (0.47
µF
typ.) be placed from the
+V
OUT
to the -V
OUT
pins for single output units and from each output to common for dual output models. To further reduce
output ripple, a 3.3
µF
is recommended.
4. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%.
5. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance
may affect the stability of the converter. In applications where the converter output loading is high and input power is
supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recom-
mended that a low ESR (ESR <1.0 at 100 kHz) capacitor be mounted close to the converter. For 12V input units a
10
µF
is recommended; for 12V input units, a 4.7
µF;
and for 24V units a 2.2
µF.
6. Operation at no-load will not damage the unit, but they may not meet all specifications.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection tables for
the correct rating.

IGBT Applications
Notes:
The
MHI1000x-xxB
series is a good
choice for applications involving high
speed switching, such as driving IGBTs.
They are designed to withstand the
extra stress caused by the high voltage
switching transients present in IGBT
drive circuits.
All of the
MHIxxx
series have isolation
levels that range from 5.2 to 8 kV. Many
of these have reinforced insulation. The
high isolation levels (and the correspond-
ingly low capacitive coupling rates) allow
them to be safely used in applications
with highly dynamic switched AC or DC.
