Output
1.
When measuring output ripple, it is recommended that an external
0.47 F ceramic capacitor be placed from the +Vout pin to the -Vout
pin for single output units and from each output to common for dual
output units. For noise sensitive applications, the use of 3.9 F
capacitors will reduce the output ripple.
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. However, they may
not meet all specications.
5.
Dual output units may be connected to provide a 10 VDC, 24 VDC
or 30 VDC output. To do this, connect the load across the positive
(+Vout) and negative (-Vout) outputs and
oat the output common.
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 Equivalent Series Resis-
tance (ESR <1.0 at 100 kHz) capacitor be mounted close to the
converter. A 10.0 F is recommended for 24V input models; a 4.7 F
for 48V units.
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.

Remote ON/OFF Notes:
1. Maximum sink current at the on/off pin (pin 6) during a logic
low is 100 A.
2. Maximum allowable leakage current of a switch connected to the
on/off terminal (Pin 6) at logic high (2.5V to 100V) is 50 A.
