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 +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 > +25°C 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 +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. Due to requests in market and advances in technology, specifications subject-35 to -change without notice.
