Notes:

at 100% load.The second auxiliary output is varied from 25% to 100%

load.

2. When measuring output ripple, it is recommended that an external

ceramic capacitor (approx 4.7 - 10 µF) be placed from each output to

common.

3. Transient recovery is measured to within a 1% error band for a load step

change of 25%.

4. Short circuit protection is provided by a “hiccup mode” circuit.

5. If the on/off pin is left open, the unit operates. If it is grounded, the unit

will shut off. THe control circuit is referenced to the minus (-) input.

6. 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.

7. These units should not be operated over +85°C. Exceeding +85°C may

damage the unit.

8. It is recommended that a fuse be used on the input of a power supply

for protection. It is recommended that a slow blow fuse rated at 6,000

mA be used with the 24V input models and a 3,000 ma fuse be used

with 48V input models.
