BVS SERIES UNIVERSAL INPUT GENERAL SPECIFICATIONS AC Input: BVS products automatically adjust to the input voltage as follows: BVS30, 40, 60, 80: wide range input from 90-264 VAC DC Outputs: See Voltage/Current Rating Charts. Output Power: See Voltage/Current Rating Charts. Peak Output Power: See Voltage/Current Rating Charts. Sixty second maximum peak power durations. A 10% duty cycle is not to be exceeded when peak power durations are combined. Brown-Out Voltage: Regulation is maintained with full rated load at 90 VAC Hold-Up Time: 20 msec typical at full rated load and nominal AC input voltage. Hold-up time increases to 40 msec at 50% load. Power-Fail Warning Signal: TTL compatible signal goes low before the main +5V output drops 5%, at full rated load on BVS 80 Typical warning time: BVS 80 : 5 msec where applicable Warning time increases at reduced load levels Efficiency: Measured at full rated load and nominal AC input voltage. 75% ±5% depending on how the load is distributed among the outputs. Regulation Characteristics: See Voltage/Current Rating Charts for individual model ratings. Measurement method: Line: Measured over a 90-132 VAC or 175-264 VAC line change. Load: Measured over a 20% to 100% load change. Multiple output model regulation is subject to the minimum load requirements mentioned below. Minimum Loads: The following minimum loads are required to maintain regulation. Multiple output models are expressed as current on the main output. Multiple output Single output BVS 80 1A 5 Watts BVS 40, 60 0.5A 3 Watts BVS40 board only models: Consult factory for minimum load requirements. Please note that minimum load requirements increase at temperatures over 50°C. Initial Setting Tolerance: Measured at 50% of full rated load on all outputs. Remote Sensing: Optional on selected models only. Output Noise and Ripple: 0.3% RMS, 1% PK-PK maximum on main +5V output. Transient Response: Main +5V output: 500 µsec typical for a 50-100% load change and recovery to within 1% of initial voltage set point. Maximum excursion: 4% from initial voltage set point. Overload Protection: Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition. Delayed-foldback current limiting characteristics assure reliable turn-on into reactive and non-linear loads. Overvoltage Protection: Provided on the main +5V output. Factory set at 6.2V±0.6V. Power-Up Initialization Period: Typical 2.0 sec turn-on delay assures orderly ramp-up and stabilization of all output voltages during power-up. Input Protection: AC input line fuse provided. Internally located. Inrush Current: Internally limited by thermistor. Temperature Rating: Operating: 0°C to +50°C at full rated output power. Derate linearly to 50% of full load from 50°C to 70°C. Storage: -55°C to +85°C. Temperature Coefficient: ±0.03%/°C typical, ±0.05%/°C maximum over entire operating temperature range of 0°C to +70°C. Cooling: Convection cooling is adequate for convection power ratings providing that non-restricted convection air movement is available. When operating in a confined area, forced air cooling is recommended. See voltage/current rating charts for individual model airflow requirements. Vibration: Random vibration from 10Hz to 2KHz, 6.15 grms (3 axis). Shock: Operating: 20G peak acceleration.
