General Specifications Datasheet PDF AC Input:
BVS products automatically adjust to the input voltage as follows: BVS30, 40, 60 and 80: wide range input from 90-264 VAC
DC Outputs:
See Voltage/Current Rating Charts.(Standard Models)
Output Power:
See Voltage/Current Rating Charts.(Standard Models)
Peak Output Power:
See Voltage/Current Rating Charts.(Standard Models)
Sixty second maximum peak power duration’s. A 10% duty cycle is not to be exceeded when peak power duration’s 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
|   | 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 those 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 sec 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.
Safety Agency Certifications:
- UL 1950 without D3 deviation, file #E181899
- CSA C22.2 No. 950, UL file #E181899
- CE Marked
