-25- H HiTRON PCB-MOUNT DC-DC CONVERTER ENCAPSULATED MODULES INDUSTRIAL GRADE 25 WATTS DUAL OUTPUT HDM25-D SERIES FEATURES: DUAL OUTPUT 2:1 INPUT RANGE 25W ISOLATED OUTPUT SIX-SIDED METAL SHIELD GENERAL SPECIFICATION Efficiency: 77-85% typical, various with input. Switching Frequency: Fixed frequency 450K Hz. Circuit Topology: 450K Hz. Forward Circuit. Transient Response: Max. excursion 140mV, Recovery time <200 µSec. @ 25% step load change. Case: Black coated copper with non-conductive metal base. Power Density: 10.0 Watts. / Cubic inch. MTBF: 1,000,000 hours to Mil. Std. 217, 25°C. Operating Temperature: Industrial Grade -25°C to +85°C range. 0°C to+70°C @ full load without derating. From+70°C derating linearly to half load @ +85°C. (Refer to the Derating Chart for commercial grade.) Temperature: -40°C to +105°C for industrial grade. Temperature Coefficient: ± 0.03% /°C. Humidity: Up to 95%RH, Non-condensing. Cooling: Convection cooling up to+70°C @full load. At least 100LFM moving air is recommended for full load >+71°Cin a confined area. Industrial Grade for 12B/24B/48B input. Commercial Grade only for 5B input. NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise specified. (2) Line Regulation measured from High to Low Lines at full load. (3) Load Regulation measured from Full Load to 1/2 Full Load at nominal input. (4) Correct fuse size by calculating the max. DC current drains at low Line input & Load and then adding 20-25% for the desired fuse size. OUTPUT SPECIFICATION Output Voltage: See Ratings Chart. Output Current: See Ratings Chart. Voltage Accuracy: Main O/P ±2.0 % typical. Line Regulation: ± 0.06% typical. Load Regulation: VO1 ±0.60 %, VO2 ±0.5% typical. Noise & Ripple: 1.0% typical. OVP: Built-in on main output VO1. Adjustability: VO1 O/P may optionally be external trimmed ±3.0% with a fixed resistors or trim-pot. Short Circuit Protection: Power fold back, and self-recovering. 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. SPECIFICATION INPUT SPECIFICATION Input Range: 2:1 DC input range: Input Voltage: Nominal 5/12/24/48Vdc. Input Current: Various with input range and load. Input Fuse: Use external fuse. Input Filter: Pi-Network. Input Reflect Ripple Current: 45mA typical. Isolation Resistor: 1,000 Mega Ohms. Isolation Voltage: 1,500Vdc. EMI: Six-sided metal shielding. 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). Due to requests in market and advances in technology, specifications subject to change without notice.
