1.0 DESCRIPTION
1.1 FEATURES
The VHR series of industrial grade DC-DC converters provides cost
effective, high reliability solutions for use in defense, avionics and
manufacturing industries. The VHR industrial grade products
leverage decades of VPT's proven heritage in military and
aerospace electronics.
• High Reliability at Low Cost
• 5 Watts Output Power
• Wide Input Voltage Range: 15 to 50 Volts per MIL-STD-704 and
MIL-STD-1275
• High Input Transient Voltage: 80 Volts for 1 sec per
MIL-STD-704A
VPT’s VHR5-2800S series is ideal for non flight-critical solutions in
military, avionics, unmanned systems as well as manufacturing
equipment and controls. A wide input voltage range which
accommodates nominal 28 V inputs, low input and output ripple,
fixed operating frequency and companion EMI filters simplify
system design while ensuring operating success in the most rugged
of environments.
• Input Undervoltage Lockout
• Fixed Frequency
• Output Soft Start
• Current Limit Protection
• Short Circuit Protection
• Magnetic Feedback, no Optoisolators
• Wide Temperature Range, -40 °C to 100 °C
• Internally Conformal Coated
• Standard Six Sided Non-Hermetic Rugged Metal Package
These converters are designed and manufactured in a facility
certified to ISO9001, J-STD-001 and IPC-A-610.
