Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
Notes
1. On dual output models the maximum combined output power is 70 watts.
A maximum of 95% (66.5 W) is available from any single output.
2. On triple output models the maximum combined output power is 60 watts.
A maximum of 50 watts is available from a single output.
3. Balanced loads
4. Regulation effect on the negative dual output during the defined conditions.
5. Regulation effect on both dual outputs during the defined conditions.
