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. Remark: Voltage refer to –Input (-Vin). 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. Due to requests in market and advances in technology, specifications subject to change without notice. -39- INPUT/OUTPUT & VOLTAGE/CURRENT RATINGS CHART SINGLE OUTPUT MODEL NO.
