| * SINGLE OUTPUT UP TO 15A * INDUSTRY STANDARD FOOTPRINT * ADJUSTABLE OUTPUT VOLTAGE * NO MINIMUM LOAD * UNDER-VOLTAGE LOCKOUT * HIGH EFFICIENCY UP TO 91% * COMPACT 2.40 X 2.28 X 0.50 INCH PACKAGE * FIXED SWITCHING FREQUENCY * HALT TESTED HEC50-S single output DC/DC converters provide up to 50 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 15A current rating. 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 HEC50 converters are especially suited to telecom, networking and industrial application.

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 T/C. 3. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models. Power mate suggest: Nippon chemi-con KMF series, 220 F/100V, ESR 90m . 4. The negative/ positive logic and pin length are optional ( see table ). The pin voltage is referenced to negative input. 5. 24V input models safety approval pending. 6. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024. 7. The HEC50 meets level A and level B conducted emissions only with external components connected before the input pin to the converter. 8. Maximum value at nominal input voltage and full load. 9. Typical value at nominal input voltage and full load. 10. BASEPLATE GROUNDINGBase-plate should be grounded at one of the four screw bolts prior to operation. 11. The converter is provided by basic insulation. ( Note 10 ) 1. EXTERNAL OUTPUT TRIMMING Output can be externally trimmed by using the method shown below.
