nOTES: TRIPLE OUTPUT MODELS

1. guaranteed by design, not tested.

2. Up to the maximum specified auxiliary output current/power is available from either auxiliary output provided the total auxiliary output current/

power does not exceed the total current/power specified .

3. To maintain tight regulation over the full input voltage range a minimum load of 2% of full load should be used on all outputs.

4. To maintain the cross regulation specification, one of the auxiliaries must always provide a minimum of 20% of the total auxiliary power used.

negative Vout cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power - full load).

5. Cross regulation is measured under the following conditions:

6. Converters meet MIL-STD-461 specification revisions for conducted emissions C-CE03 and D-/E-/F-CE-102. The actual value of input ripple

current is much less, the limit in the characteristic table is based on measurement resolution.

7. Efficiency measured with all outputs at full load.

8. Maximum power dissipation when all outputs are shorted simultaneously.

10. Transition time >10 µs.

11. Half load to/from full load.

12. Measured from release of inhibit or input voltage step.

Electrical Characteristics: -55°C to +125°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.
