HEC75-SERIES DC/DC converters provide up to 75 watts of output power in an industry standard half-brick package and footprint. These units are specifically designed to meet the power needs of low-voltage silicon. All models feature a wide input range, trimmable output voltage and a 20A current rating (15A for dual output). Remote sense and remote on/off facilities are included as standard, and the converters are comprehensively protected against over-current, over-voltage and over-temperature conditions. The HEC75 converters are especially suited to telecom, networking and industrial application.

Note

1. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used, the +V sense should be connected to its corresponding +OUTPUT and likewise the- sense should be connected to its corresponding –OUTPUT.

2. Measured with a 1uF M/C and a 10uF M/C(for dual outputs) or 1uF M/C and a 10uF T/C(for single outputs).

3. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V models. Power mate suggest: Nippon chemi-con KMF series, 220F/100V, ESR 90m.

4. The negative / positive logic and length are optional ( see table ). The pin voltage is referenced to negative input.

5. Dual output safety approvals pending.

6. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at Tc=40ºC. (Ground fixed and controlled environment)

7. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024.

8. The HEC75 meets level A and level B conducted emissions only with external components connected before the input pin to the converter.

9. Maximum value at nominal input voltage and full load.

10. SingleTypical value at nominal input voltage and full load.

DualThe efficiency test condition: Nominal input voltage and both outputs current are 7.5A.

11. BASEPLATE GROUNDINGBase-plate should be grounded at one of the four screw bolts prior to operation.

12. The converter is provided by basic insulation.
