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.
