Mechanical Notes:

Notes:

1. When measuring output ripple, it is recommended that an external 3.3 µF ceramic capacitor be placed from the

2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%.

3. Operation at no-load will not damage these units.

4. An external 220 µF/100V capacitor connected across the input pins is required to meet EN61000-4-4 and

EN61000-4-5.

5. Dual output units may be connected to provide a 10, 24 or 30 VDC output. To do this, connect the load across the

6. 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 recommended

that a low ESR (ESR <1.0

at 100 kHz) capacitor be mounted close to the converter. For

12V input units a 3.3 µF is recommended; and for 24V & 48V units a 2.2 µF.

7. It is recommended that a fuse be used on the input of a power supply for protection. See

the table above for the correct rating.
