MRH SERIES

15 WATT

Notes

1. Maximum combined output power is 15 watts for both dual and triple models.

Dual output models: The maximum specification is the total output current/power.

Up to 80% of that total is available from either output provided the positive output maintains a minimum of 20% of the total power used.

Triple output models: The maximum combined power of the auxiliaries is 6 watts, of which 100% is available from either output.

2. Load regulation is not guaranteed below minimum load.

4. Indefinite short circuit protection is not guaranteed above 85°C case.

Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, unless otherwise specified.
