Unique to the DVAB series are independent dual control loops which provide tight regulation and zero cross regulation error while maintaining high efficiency. Operating at a nominal fixed frequency of 325 kHz, per stage, these regulated, isolated units utilize a high speed magnetic feedback design and well controlled undervoltage lockout circuitry to eliminate slow start-up problems. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL- PRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 FEATURES • High Reliability • Very Low Output Noise • Wide Input Voltage Range: 15 to 50 Volts per MIL-STD-704 • Dual Outputs with Zero Cross Regulation Error • Up to 15 Watts Output Power • High Input Transient Voltage: 80 Volts for 1 sec per MIL-STD-704A • Fault Tolerant Magnetic Feedback Circuit • NO Use of Optoisolators • Undervoltage Lockout • Short Circuit Protection • Current Limit Protection • Precision Projection Welded Hermetic Package • High Power Density • Custom Versions Available • Additional Environmental Screening Available • Meets MIL-STD-461 Revisions C, D, E and F EMC Requirements When Used With VPT’s EMI Filters • Flanged and Non-flanged Versions Available. • MIL-PRF-38534 Element Evaluated Components Figure 1 – DVAB2800D / DVAB2800DF DC-DC Converter ( Exact marking may differ from that shown) |
