Notes:
1. Start up time is measured at nominal input and with a constant resistive load.
2. Cross regulation is measured with the output being tested at 50% load. The second output is
varied from 10% to 100% load.
3. When measuring output ripple, it is recommended that an external ceramic capacitor (approx
1 µF to 10 µF) be placed from the +VOUT to the -VOUT pins.
4. Transient recovery is measured to within a 1% error band for a load step change of 25%.
5. Short circuit protection is provided by a “hiccup mode” circuit.
6. Isolation capacitance for 24 VDC output models is 2,000 pF. Isolation capacitance is measured
from input to output at 100 kHz/0.1V.
7. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The
maximum control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off
pin is left open, the unit operates. If it is grounded, the unit will shut off.
8. These units should not be operated with a load under 10% of full load. Operation at no-load will
not damage the unit, but they may not meet all specifications.
9. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.
10. It is recommended that a fuse be used on the input of a power supply for protection. See the
Model Selection table above for the correct rating.
Derating Curve
External Trim
External Trim Notes:
On single output units, an external resistor can be used to adjust the converter
output up/down by about 10%. The connection is shown in the diagram at left. The
required resistor value is calculated by the formulas:
Trim UP = RTRIM = A $-R2 - R3
R2 A
Trim Down = RTRIM = A $-R1 - R3
R1 A
Where A =
VREF
$ R1
VTRIM - VREF
Where A = VTRIM VREF $ R2
VREF
Where RTRIM = The value of the external trim resistor
VTRIM = The amount of voltage adjustment required
The value of R1, R2, R3 and VREF are given in the table below.

Notes:
1. All units are rated for EN 55022 (CE/RE) class A without external components.
They will meet class B with the addition of the MDCFM-0x (or a similar discrete
filter circuit). Contact the factory for more information.
2. To meet the requirements of EN 61000-4-4 (±2 kV), external components are
needed. This can be done discretely, or with the addition of the MDCFM-0x.
Contact the factory for more information.
3. To meet the requirements of EN 61000-4-5 (±2 kV), external components are
needed. This can be done discretely, or with the addition of the MDCFM-0x.
Contact the factory for more information.
