| H HiTRON 02/16/2004 ON-BOARD DC-DC CONVERTER QUARTER-BRICK BASE PLATE POWER MODULES INDUSTRIAL GRADE 48-110 WATTS SINGLE OUTPUT HDH80-24B OR 48B-S SERIES FEATURES: SINGLE OUTPUT WIDE 2:1 INPUT RANGE 1500VDC ISOLATION STANDARD QUARTER-BRICK PACKAGE HIGH-EFFICIENCY POWER MODULE UNDER-VOLTAGE LOCKOUT DESIGNED TO MEET INTERNATIONAL SAFETY STANDARDS SPECIFICATION INPUT SPECIFICATION Input Range: Wide 2:1 Input DC Range 36-72Vdc or 18-36Vdc. Input Voltage: Nominal 48Vdc or 24Vdc. Input Current: Typical 2.35A full load and 0.1A no-load @ 48Vdc nominal input. Typical 4.14A full load and 0.05A no-load @ 48Vdc nominal input. Input Fuse: Use external fuse. Soft-Start: Installed. Inrush Current: Peak 2.38A @ 48Vdc & 4.3A @ 24Vdc. Input Filter: Pi-Network for EMI suppression. Under-Voltage Protection (UVP): Lock-out activated at 34-35.5Vdc input @48Vdc nominal input. 17.5-17.8Vdc input @24Vdc nominal input. Input OVP: 74-76Vdc @ 48Vdc nominal input. 37-38Vdc @24Vdc nominal input. Input Reflected Ripple Current: 8.0mA pk-pk @48 Vdc. Isolation Voltage: 1,500Vdc input-output. Remote On/Off: TTL/CMOS-Compatible input control. Positive Logic version for Standard set up: ON(Enable)=Open(or 2.5-5.0Vdc above-Vin) OFF(Disable)=Short(or 0-0.8Vdc above-Vin) Negative Logic version option available by adding a "N" suffix to the end of Model #. Remark: Voltage refer to -Input (-Vin). OUTPUT SPECIFICATION Output Voltage: See Ratings Chart. Output Current: See Ratings Chart. Output Wattage: 48-110W typical continuous. Line Regulation: 0.1% typical. Load Regulation: Various with output voltage. 0.5% typical. Noise & Ripple: 1% rms typical. OVP: Built-in (latch). Adjustability: Factory set. Maybe externally trimmed with fixed resistor or trim pot. Overload Protection (OLP): Fully protected against output overload and short circuit. OLP set at about 125-150% rating output wattage. Consult the factory for OLP setting. GENERAL SPECIFICATION Efficiency: 88-90% typical, various with input & output. Switching Frequency: Fixed frequency 330K Hz. Circuit Topology: 330K Hz. Forward Circuit. Transient Response: Peak transient 150mV and recovers within 2mS after 25% load-change. Safety Standard: IEC60950 Class II. Case: Aluminum base plate with metal standoffs. Power Density: 29-66 Watts / Cubic inch typical. Industrial Grade. Operating Temperature: -40 to +100C (base plate) Power derating details please refer to the Derating Chart. Storage Temperature: -55 to +125 C. Temperature Coefficient: 0.02%/C. Humidity: Up to 95% RH, Non-Condensing. Cooling: At least 100LFM moving air is recommended for full load > +25C room temperature in a confined area. Air flow vs. Power derating details, please refer to the Derating Chart. NOTE: (1) All measurements are at nominal input, full load, and +25C unless otherwise spec. (2) Line Regulation measured from High to Low Lines at full load. (3) Load Regulation measured from Full-Load (F-L) to Half-Load(H-L)at nominal input. (4) Correct fuse size by calculating the max. DC current drain at low Line input & adding 20-25% for desired fuse size. Due to requests in market and advances in technology, specifications subject to -35 change without notice.
