1 / 2 page -39- H HiTRON ON-BOARD DC-DC CONVERTER HALF-BRICK BASE PLATE POWER MODULES INDUSTRIAL GRADE 165-200 WATTS SINGLE & DUAL OUTPUT HDH165-24B OR 48B-S & D SERIES FEATURES: SINGLE OUTPUT WIDE 2:1 INPUT RANGE 1500VDC ISOLATION STANDARD HALF-BRICK PACKAGE HIGH-EFFICIENCY POWER MODULE UNDER-VOLTAGE LOCKOUT DESIGNED TO MEET INTERNATIONAL SAFETY STANDARDS GENERAL SPECIFICATION Efficiency: 87.5-89% typical, various with input & output. Switching Frequency: Fixed frequency 330K Hz. Circuit Topology: 330K Hz. Forward Circuit. Transient Response: Peak transient <220mV and recovers Within 1mS after 25% load-change. Safety Standard: IEC60950 Class I. Case: Aluminum base plate with metal standoffs. Power Density: 60 Watts / Cubic inch typical. Operating Temperature: -40 to +100°C (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 > +10°C in a confined area. Air flow vs. power desrating details please refer to the Derating Chart. Industrial Grade. NOTE: (1) All measurements are at nominal input, full load, and +25°C 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. SPECIFICATION INPUT SPECIFICATION Input Range: Wide 2:1 Input DC Range 36-72Vdc or 18-36 Vdc. Input Voltage: Nominal 48Vdc or 24Vdc. Input Current: Typical 7.84A full load and 0.2A no-load @ 24Vdc nominal input. Typ.3.92A full load and 0.1A no-load @ 48Vdc nominal input. Input Fuse: Use external fuse. Soft-Start: Installed. Inrush Current: 4A @ 48Vdc. 8A @ 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 Reflected Ripple Current: 20mA 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: 165-200Watt continuous typical. Line Regulation: Various with input & output voltages. ± 0.1% typical. Load Regulation: Various with output voltages. ±0.5% typical. Noise & Ripple: 1% rms typical. OVP: Built-in (latch). Adjustability: Maybe externally trimmed with fixed resistor or trim pot. Overload Protection (OLP): Fully protected against overload and short circuit. OLP set at typical 130% rating output wattage load. Consult the factory for special OLP setting. Due to requests in market and advances in technology, specifications subject to change without notice. |
